This survey research based study sought determinants of biogas technology adoption in rural areas of Pakistan. Stratified random sampling technique was employed to select respondents because the population was unknown and heterogeneous in nature. Total 240 respondents (150 biogas users and 120 potential users) were selected and face to face interviewed using a structured, validated and pre-tested questionnaire. Along with descriptive analysis of data logistics regression model was applied to investigate the determinants of biogas adoption. Findings affirmed significant role of socio-economic characteristics of respondents in the adoption of biogas technology. Empirical findings reported a significant impact of education, the income of households and the number of animals on the adoption of biogas technology. This implies that unit increase in education, income and number of animals will escalate the adoption of biogas technology. Tackling energy crisis, economic benefits, and production of slurry for soil fertility, health gains and environment-friendly nature of biogas were perceived reasons of biogas adoption among the biogas users. Non-government organizations and neighbours were leading motivational factors behind adoption as revealed by users. However, role of electronic media, print media and government institutionsin promoting biogas was reported dismal. This study urge that biogas is valuable alternative source of energy to combat energy crisis. In this way, provision of subsidies, interest free loans and technical backstopping could invoke potential users to adopt biogas technology.

Full textAbstract:
Biogas is a renewable energy source consisting mainly of methane, carbon dioxide, and other impurities. A purification process is required to remove the impurities (biogas upgrading and purification) to meet the requirements as an energy source for vehicles. Removal of CO2 from the biogas stream, which accounts for about 40% of the impurities, is necessary to produce biogas (mainly methane) for use in vehicles. Chemical absorption of CO2 using a rotating packed bed was considered due to its high CO2 absorption efficiency and small column size. Aspen Plus and Visual Fortran software were used to develop the model, and monoethanolamine (MEA) was used as the absorbent. The developed model was validated with experimental data, where the relative error is less than 10%. The process analysis performed shows: (a) biogas purity increases with rotation speed. (b) An increase in lean solvent concentration leads to an increase in CO2 capture efficiency and biomethane purity. (c) An increase in biogas throughput leads to an increase in biogas purity. The study may be useful for the design and operation of intensified CO2 capture from biogas streams for vehicle applications.

Full textAbstract:
While energy-related sectors remain significant contributors to greenhouse gas (GHG) emissions, biogas production from waste through anaerobic digestion (AD) helps to increase renewable energy production. The biogas production players focus efforts on optimising the AD process to maximise the methane content in biogas, improving known technologies for biogas production and applying newly invented ones: H2 addition technology, high-pressure anaerobic digestion technology, bioelectrochemical technology, the addition of additives, and others. Though increased methane concentration in biogas gives benefits, biogas upgrading still needs to reach a much higher methane concentration to replace natural gas. There are many biogas upgrading technologies, but almost any has methane slip. This research conducted a life cycle assessment (LCA) on membrane-based biogas upgrading technology, evaluating biomethane production from biogas with variable methane concentrations. The results showed that the increase in methane concentration in the biogas slightly increases the specific electricity consumption for biogas treatment, but heightens methane slip with off-gas in the biogas upgrading unit. However, the LCA analysis showed a positive environmental impact for treating biogas with increasing methane concentrations. This way, the LCA analysis gave a broader comprehension of the environmental impact of biogas upgrading technology on GHG emissions and offered valuable insights into the environmental implications of biomethane production.

To combat climate change, the Chinese government has implemented a package of policies to support the development of the biogas power generation industry. However, the promotion of biogas power generation technology in China is relatively slow. Therefore, it is of practical significance to study the promotion of biogas power generation technology against the background of policy support. In order to study the effect of policy on the promotion of biogas power generation technology, a system dynamics model is constructed in this paper. The results show that under the feed-in tariff subsidy policy, biogas power generation technology can be well promoted because it has good economic and environmental effects. In addition, if the biogas power generation technology is considered to participate in carbon emission trading, the carbon price also has a positive impact on the promotion of biogas power generation technology because it increases the perceived economic value of biogas power generation projects. Finally, this study can also provide reference value for the promotion of biogas power generation technology in other areas.

Full textAbstract:
Globally, biogas technology has been touted by academics, international organizations, United Nations, and pressure groups, among others, as an effective tool for protecting the planet against degradation. As such, stakeholders in the biogas technology sector have made some policy recommendations toward that goal. These include a global campaign in support of energy for sustainable development, climate financing by the international community, all countries adopting appropriate national strategies, innovative financial mechanisms, and encouraging private-sector participation in achieving the goal. Clearly, for countries to promote accessibility and create favorable perceptions on the adoption of biogas technology requires institutional involvement and collaboration. That is, institutions need to participate and contribute in terms of ideas and expertise as well as work together to ensure the dissemination and uptake of biogas technology in Ghana. This study is aimed at assessing the level of institutional involvement and collaboration and barriers to biogas technology dissemination in Ghana. A qualitative method was employed, and data were collected from 101 respondents through interviewing. The results indicated that the involvement of government and financial institutions in disseminating biogas technology was low, while biogas service providers showed moderate involvement. With regard to collaboration, it was revealed that institutions moderately collaborate in awareness creation but had low collaborations for promotion, monitoring, and evaluation. Furthermore, the lack of a national biogas policy, low government commitment towards biogas technology, and low financial support were key barriers to effective institutional involvement and collaboration in disseminating biogas technology in Ghana. It is recommended that the government shows a high commitment by providing the needed resources for dissemination activities and task the Ghana Energy Commission to formulate a national biogas policy to facilitate dissemination and adoption. Finally, a national biogas steering committee composed of all relevant stakeholders, including the Finance Minister or a representative from the Finance Ministry would create a good platform to help champion the dissemination of biogas technology in Ghana.

Abstract. Hydrogen sulfide in biogas is one of the most obstructive factors on utilization of biogas as fuel gas. At present, a domestic desulfurizing process of biogas in wide-spead use is the ferric oxide process. But this process has its disadvantages: the high cost and difficult regeneration of the desulfurizer, the secondery pollution the process caused. As a new technique, the bio-desulfurization of biogas has drawn more and more attention recently. This dissertation, with the experience of engineering abroad bio-desulfurization, is focused on providing a clue or a reference for the research and application of this technique in the future.

Full textAbstract:
The potential of biogas to decarbonize society depends partially on the success of small-scale systems. Two specific locations where biogas units can be implemented are considered in this study: small farms and small isolated populations. The access to energy sources, either traditional or renewable for these is often restricted and typically costly. Clean raw biogas can be the energy source to satisfy power generation, cooking, and heating needs. Upgrading widens the options to transport fuel and energy storage helping positively in the unlinking between production and demand. Water upgrading has three essential and exclusive benefits that make it a highly feasible solution for these isolated locations or small agricultural units. It is in general available in these places; it has a very low environmental impact if leakage or malfunctioning of the system, and has no toxicity per se. To aid the development of the biogas industry focused on small-scale systems a fast, easy to use, low cost, customizable tool is needed to help the design process of the high-pressure water upgrading units. The present study covers the development of such a tool. In the present report, the basis of the model to solve the mass balance of the system and to calculate the dimensions of the scrubber are described. The scrubber model is an implementation of the NTU-HTU model proposed by Billet and Schultes in two major publications (Billet, 1995) and (Billet & Schultes, 1999). The strategies used to solve the set of closed loop equations, and iterations are presented in a block diagram fashion. The tool was developed in visual basic for applications using Excel as the hosting application. The results of the tool are compared against those obtained from the same model ran in Aspen Plus. To perform such a comparison, 540 cases were used. The cases are the result of running three nominal raw biogas flows, using three different packing materials, varying the raw biogas and water flows, varying pressure, temperature, and height of the scrubber, and varying the pressure of the flash tank. Three sensitivity analyses are performed to check the influence of some variables in the model. One is designed to check the influence of the exponent choice for dimensionless numbers in the calculation of the volumetric mass transfer coefficient as an example of the various points where the Billet model is adjusted to follow the behavior of packed columns. Another analysis consists of comparing the results of height using different packing materials to see how the six packing constants affect the results of the calculations. The third analysis is performed to check the influence of the methane absorption model where three different approaches were used. The results show that the tool behaves coherently, and a validation step can be implemented via real experimental tests comparison. The tool has several points where adjustments can be made, like the mentioned exponents for the dimensionless numbers, or the constants used in the interfacial area calculation and the correction of the 𝐶𝑆 and 𝐶𝐹𝑙 packing constants when inversion point has been reached. The implementation of high-pressure water scrubbing together with a flash tank can achieve slip values as low as 0.25% or even lower. The lower the slip, the higher the energy needed to upgrade is. Thus, there is a trade-off between slip and internal energy demand.<br>Potentialen hos biogas för att minska samhällets kolberoende är delvis beroende avframgången för småskaliga system. I denna studie betraktas två specifika platser där biogasenheter kan användas: små lantbruk och små isolerade byar. Tillgången till energikällor, såväl traditionella som förnybara, är ofta begränsad och är vanligtvis dyr för dessa platser. Renad biogas kan bli enenergikällan för att tillgodose kraftproduktion, matlagning och uppvärmning. Biogasuppgradering breddar användningsalternativen till användning som drivmedel och till energilagring, vilket bidrar på ett positivt sätt till koppla isär energiproduktion och energiförbrukning. En vattenskrubber har tre viktiga och unika fördelar som gör den en väldig användbar lösning för dessa isolerade platser eller för små jordbruksenheter. Vanligtvis är vatten tillgängligt på dessa platser, det har en synnerligen låg miljöpåverkan om det blir läckor eller funktionsfel i systemet och det är icke-giftigt. För att stödja utvecklingen av biogasindustrin med inriktning på småskaliga system behövs ett snabbt, lättanvänt, billigt och anpassningsbart verktyg för att genomföra design en högtrycks vattenskrubber. Den här studien omfattar utvecklingen av ett sådant verktyg. I föreliggande rapport beskrivs grunden för modellen för att lösa systemets massbalans och att beräkna och dimensionera skrubbern. Skrubber-modellen innehåller en implementering av NTU-HTU-modellen som Billet och Schultes föreslagit i två stora publikationer (Billet, 1995) och (Billet & Schultes, 1999). De strategier som används för att lösa uppsättningen av slutna loop-ekvationer och iterationer presenteras i ett blockdiagram. Verktyget har utvecklats i VBA (Visual Basic for Applications) och använder Excel som programvarumiljö. Resultaten som erhålls med det utvecklade verktyget jämförs med de som erhålls från samma modell i Aspen Plus. För att utföra en sådan jämförelse användes 540 testfall. Fallen är resultatet av modelleringen av tre nominella biogasflöden, där tre olika typer av fyllmaterial/fyllkroppar används. För varje testfall varieras rå biogas, vattenflöde, tryck, temperatur och höjd av vattenskrubbern, samt trycket i flash-tanken. Tre känslighetsanalyser utförs för att kontrollera påverkan av vissa variabler i modellen. Den första är utförmad för att kontrollera exponeringsvalets inverkan på dimensionslösa tal vid beräkningen av den volymetriska massöverföringskoefficienten, som ett exempel av flera punkter där Billets modell är justerad för att följa vattenskrubbers beteendet. Den andra analysen består av att jämfora skrubberns beräknade höjd när olika fyllmaterial används för att evaluera hur påverkar de sex fyllmaterial konstanterna resultaten av beräkningar. Och den tredje analysen utförs för att kontrollera påverkan av metans absorptionsmodell när tre olika metoder användes. Resultaten visar att verktyget uppträds på ett koherent sätt och ett valideringssteg kan baserat på detta genomföras med verkliga experimentella jämförelser. Verktyget har flera delar där justeringar kan göras, som t.ex. exponenterna för dimensionslösa tal och konstanterna som används i interfaceberäkningarna, samt korrigeringen av 𝐶𝑆 och 𝐶𝐹𝑙 konstanter när punkten av inversion har uppnåtts. Implementeringen av högtrycks vattenskrubbers tillsammans med en flash-tank kan medföra en slipp (förklaras senare i rapporten) så låg som 0,25% eller ännu lägre. Ju lägre slipp är desto högre är energin som behövs för att uppgradera biogasen. Det finns således en avvägning mellan slipp och intern energiförbrukning

<p>From an environmental- and health perspective, biogas and other biomass-based fuels have several advantages; nevertheless the majority of motorists fill their cars with petroleum-based fuels. This thesis is designed to explore the profile of biogas in relation to its perceptions. It is a study concerning the communication between the biogas producing company Svensk Biogas and their biogas users and non biogas users. To obtain a thorough understanding of the profile and perceptions of biogas a qualitative approach was considered appropriate. Biogas users and non-users were interviewed at gasoline stations, while Svensk Biogas was interviewed as a group.</p><p>The three interview segments were analyzed and compared in order to identify patterns, similarities and differences. Based on research data the thesis concludes that the profiling arguments of biogas correlates to that biogas is the most environmentally friendly fuel, the least expensive fuel, and locally produced. Furthermore, the company profile of Svensk Biogas is equal to sustainable alternative, locally produced, trustworthy, environmentally friendly and climate smart [klimatsmart]. Given the arguments of the company profile, environmental values seem to be the core communicating value. Profiling Svensk Biogas happens through events and by using communication material such as company logotype.</p><p>Motorists have an overall positive perception of biogas. Biogas users states environmental benefits as the key argument behind their commitment. Non-users are positive toward biogas although expressing a lack of knowledge confusing biogas with ethanol and bio-fuels in general. According to motorists the negative perceptions, in addition to the prerequisites of biogas, are connected to insufficient infrastructure of biogas filling stations, a short range of the biogas tank, a high investment cost of a biogas car, a biogas price increase, scarcity of cars, and information (lack of information and misleading information).</p><p>The overall perception of Svensk Biogas among biogas users is positive. Biogas users express a negative perception concerning the Svensk Biogas filling stations and also wish for a lower biogas price. Non-users express modest perceptions of the company. This research also concludes that perceptions of the biogas producer are correlated to the perceptions of biogas. Furthermore, biogas producer, users and non-users wish to be directed by political decisions, guiding them toward environmentally friendly fuel alternatives.</p>

Full textAbstract:
Biogas is of growing interest in Sweden, and a public inquiry suggested the government to set a goal of producing 10 TWh biogas in 2030 although only 2 TWh biogas was produced in Sweden in 2018 (Regeringskansliet, 2019) (Klackenberg, 2019). To achieve this optimistic goal and to meet the increased demand of biogas, new biogas production facilities needs to be built. The purpose of this report is to investigate the economic feasibility for the development of a biogas recovery process adjoined to an incineration facility in Sweden. The report first gives an overview of the largest incineration facilities in Sweden. The largest quantity of food waste was estimated in Gothenburg to be 56´744 WRQ SeU \eaU. For the economic feasibility, a conceptual facility was constructed with 169´000 ton residual waste per year of which 45´000 ton was food waste. A biogas process model was built in Excel where the biogas potential was calculated using characteristics for food waste. The annual production of liquid biogas was estimated to 43´970 MWK. The economic evaluation was based on the conceptual facility. In the baseline scenario the incomes for the process was the value of liquid biogas, 25,6 MSEK per year, a Gate-fee synergy of 5 MSEK per year and a Tax deduction synergy of 1 MSEK per year. The investment cost was estimated to 211,6 MSEK and the Operation & Maintenance cost was estimated to 6,3 MSEK per year. This resulted in an NPV of 69,5 MSEK and an IRR of 10,3% for the project, indicating a profitable investment. Three different scenarios were considered, apart from the baseline scenario, where the first excluded all synergies with the incineration facility, which generated an NPV of 2,3 MSEK. The second scenario only considered the minimal gate-fee synergy which gave an NPV of 37,8 MSEK. Finally, the third scenario where all synergies were included, and an additional investment grant was introduced gave the project an NPV of 111,8 MSEK. A sensitivity analysis was also conducted which showed that the input of food waste treated, weighted average cost of capital and potential grants had the biggest impact on the financial results. None of the results from the sensitivity analysis showed a negative NPV.<br>Intresset för biogas växer i Sverige och i en statlig utredning föreslogs regeringen att sätta upp ett mål att producera 10 TWh biogas 2030 (Regeringskansliet, 2019). Detta kan jämföras med 2018 då endast 2 TWh producerades (Klackenberg, 2019). För att uppnå detta optimistiska mål och för att möta den ökade efterfrågan på biogas behöver nya produktionsanläggningar byggas. Syftet med denna rapport är att undersöka de ekonomiska möjligheterna för utvecklingen av en biogasanläggning angränsad till en förbränningsanläggning i Sverige. Rapporten ger först en översikt över de största förbränningsanläggningarna som behandlar hushållsavfall i Sverige. Det uppskattades att den största mängden matavfall som går till förbränning i Sverige är i Göteborg där 56´744 ton matavfall förbränns per år. För att bestämma de ekonomiska förutsättningarna konstruerades en konceptuell anläggning som behandlar 169´000 ton restavfall per år varav 45 000 ton består av matavfall. En biogasprocess modellerades i Excel där den potentiella biogasen beräknades baserat på matavfallets karaktäristik. Slutligen uppskattades den årliga produktionen av flytande biogas till 43´970 MWh. Den ekonomiska utvärderingen baserades på den konceptuella anläggningen. I grund-scenariot bestod inkomsterna för av den flytande biogasen som motsvarade 25,6 MSEK per år, en ´gatefee´-synergi på 5 MSEK per år och en ´skatteavdrags´-synergi motsvarande 1 MSEK per år. Investeringskostnaden uppskattades till 211,6 MSEK och Operation & Maintenancekostnaderna uppskattades till 6,3 MSEK. Detta gav projektet ett nettonuvärde på 69,5 MSEK och en internränta på 10,3% vilket indikerar en lönsam investering. Vidare undersöktes även tre olika scenarier, utöver grund-scenariot, där det första utesluter alla synergier vilket gav ett nettonuvärde på 2,3 MSEK. Det andra scenariot beaktade endast den minimala ´gate-fee´-synergin vilket gav ett nettonuvärde på 37,8 MSEK. Det tredje scenariot inkluderade alla synergier samt ett investeringsbidrag vilket resulterade i ett nettonuvärde på 111,8 MSEK. En känslighetsanalys genomfördes också som visade att tillförseln av behandlat matavfall, kapitalkostnaden och potentiella investeringsbidrag hade den största påverkan på de finansiella resultaten. Inget av resultaten från känslighetsanalysen visade ett negativt nettonuvärde.

Anaerobic digestion of farm waste has the potential to revolutionize the agricultural sector. There are four principal objectives of this report. Summarize anaerobic technology and biological function and how they affect the potential of farm scale anaerobic digest in a literary study. Economically evaluate farm scale scenarios where biogas is considered for upgrading, heating and electricity with an internal rate of return method. Simulate farm scale scenarios in the computer software Aspen Plus. In these scenarios biogas is utilised for upgrading, heating, electricity and compared to active anaerobic digesters. Investigate how polyurethane and retention of biomass effects an anaerobic digester through design of experiments. The economic evaluation was done by using the internal rate of return. The results indicate that all scenarios are warranted in different situations but that in the given scenario a CHP unit is the most profitable. Aspen simulations show great promise as a tool for evaluation of different digester systems. It could be used both for economical evaluations and in planning stages. The effects of polyurethane and retention of biomass was shown to effect the methane concentration in the test reactors with up to 15 percentage points and the biogas production with 32 percent. These two models were developed in Modde 10. Thru the literary study the importance for anaerobic digestion technologies to be adapted to conditions were they are to be deployed for them to be profitable were evident. The immense benefits of biogas production on the environment indicates the biogas production will play a part in the conversion to a sustainable energy system.

Dependence on oil imported from foreign countries affect the National Energy securitiesand Energy security of global economies has become one of the most challenging problemthat needs to be resolved as the fossil sources are fast diminishing and irreplaceable. Thealarming energy demand and consumption rate of the present global status is currentlyexponentially exceeding the rate of local supply sources, becoming an issue of concern. Alook beyond the fossils is crucial for long tern economic growth and energy security asthere are numerous uncertainties about the fossil supplies coupled with the greaterenvironmental risks encountered during exploitation. Thus the new concept for treatingethanol distillery waste anaerobically to produce Biogas- a clean renewable alternativeenergy with many applications projects sustainable and more realistic option.The research project focuses on Comparison of the Potentials and Efficacy of AnaerobicDigestion of Stillage (Wheat Stillage and Lignocellulose Stillage) from Ethanol Distilleryplants for Biogas Production. It also investigates better alternative temperature dependentStillage Anaerobic Digestion that will enhance a higher Biogas yield.Anaerobic digestions were performed in triplicate batch systems, during both mesophilic(35 °C) and thermophilic (55 °C) conditions at a period of 50-days. The reactors contained2.73g of Wheat Stillage and 5.2g of Lignocellulose Stillage samples, respectively,corresponding to 2% VS in each reactor. The inoculum was taken from either a mesophilicBiogas Plant (Gässlosa., Borås), or from a thermophilic Biogas Plant (Sobacken, Borås). AGas Chromatographic method (GC) was employed for determination of the obtained biogascomposition.The theoretical CH4 Potential for Wheat Stillage and Lignocellulose Stillage is 0.473m3CH4/kg VS and 0.407 m3CH4/kg VS, respectively. The results obtained from this studyindicated, however, that the Wheat Stillage performed better under thermophilic conditionswith a peak of 575ml CH4 / 0.5g VS; while the Lignocellulosic Stillage gave the bestperformance under mesophilic conditions leading to a methane production of 436ml CH4/0.5g VS after 4 weeks of digestion period.<br>Uppsatsnivå: D

Full textAbstract:
This master thesis investigated the availability of raw materials for biogas production in the city of Medellín, Colombia. By first studying the development of biogas and its use as a vehicle fuel in the city of Linköping, Sweden, a comparison was made in order to focus on high-yield substrates. The objective was to calculate potential production given the amounts and types of substrates found locally and comparing it with the estimated demand of a local bus fleet that is planned to run on natural gas. The assessment of the raw materials was made in situ. The planned sources were visited in order to get information that would be later on analyzed for estimating its production potential. These sources were originally a municipal wastewater treatment plant, two slaughterhouses and two biodiesel plants. The wastewater treatment plant is already producing biogas, resulting from the treatment of sludge in anaerobic digesters. Nevertheless, calculations showed that current production is around 54% that of theoretical potential. Regarding the slaughterhouse, several important flows were detected, although some of them would not be currently available for biogas production, as they already have a defined use. The case for biodiesel production in the city was not very successful, as the two plants that were planned to be analyzed, have not started operations yet. However, some assumptions were made and some figures were calculated for further conclusions and analyses. During the visit, some other interesting sources were detected and were included in this report, such as another wastewater treatment plant, two fruits and vegetables markets, two landfills and biodiesel production in other areas. Several interesting points were discussed and analyzed through a comparison of the two cities. Drivers, barriers, actors, raw materials and production capacity were summarized and compared, resulting on reflections and conclusions. The results were also interesting, showing that the biogas potential at the two wastewater treatment plants would be enough to fuel the system and that if the other sources were to be used, excess biogas would be available for other uses, e.g. private cars or injection into the natural gas grid.<br>Det här examensarbetet undersöker tillgången på råvaror för biogasproduktion i Medellín, Colombia. Genom att först studera utvecklingen av biogas och dess användning som bilbränsle i Linköping, Sverige, gjordes en jämförelse för att fokusera på hög substrat avkastning. Syftet var att beräkna möjlig produktion utifrån de mängder och typer av substrat som går att finna lokalt, och därefter jämföra detta med ett bussbolags uppskattade efterfrågan av naturgas. Värdering av råvaror gjordes in situ. De planerade källorna besöktes för att få information som senare kan analyseras för att värdera dess produktionsmöjlighet. Källorna var ursprungligen ett avloppsreningsverk, två slakterier och två biodiesel produktionsverk. Avloppsreningsverket producerar redan biogas, med vattenrengöring på anaeroba slam digestorer. Trots detta visade beräkningar att nuvarande produktion utgjorde ungefär 54% av den teoretiska möjligheten. I fråga om slakteriet, upptäcktes flera viktiga flöden, även om några inte skulle vara tillgängliga för biogasproduktion, då de redan användes för något annat. Studien om biodiesel produktionen i staden var inte lyckad, eftersom de två produktionsanläggningarna som skulle analyseras, ännu inte startat sina verksamheter. Dock var några antaganden gjorda och några siffror beräknade för ytterligare slutsatser och analyser. Under besöken upptäcktes några andra intressanta källor, så som andra avloppsreningsverket, två frukt- och grönsaksmarknader, två soptippar samt biodiesel produktion i andra områden. Flera intressanta punkter har diskuterats och analyserats genom jämförelsen mellan de två städerna. Förare, hinder, aktörer, råvaror och produktionskapacitet sammanfattades och jämfördes, vilket resulterat i reflektioner och slutsatser. Resultatet var också intressant, då det visar att potentialen för biometan på de två reningsverken skulle vara tillräcklig för att driva systemet, samt om andra källor användes skulle det finnas överskott på biometan för annan användning, t.ex. personbilar eller injektioner i naturgasnätet.

Full textAbstract:
I detta examensarbete studerades metanpotentialen för brunalger och rödalger som hämtades vid två olika tillfällen. Förutsättningarna för att tång och alger ska kunna användas som substrat för biogasproduktion samt vilken miljönytta som kan uppnås undersöktes också. Satsvisa försök har gjorts i laboratoriemiljö genom att ta reda på metanpotentialen för de olika substraten. Biogasproduktion skedde i en syrefri rötningsprocess som innebar ett komplext förlopp där olika mikroorganismer sönderdelade substratet i flera steg för att slutligen bilda biogas samt en rötrest. Ympen som användes i försöket kom från en biogasanläggning och bestod av en blandning av naturgödsel och organiska restprodukter från slakterier och annan industri. Substratblandningar mellan tång och rötrest undersöktes genom satsvis teströtning i 15 flaskor under mesofila förhållanden, 37 °C. Gasmätningar utfördes kontinuerligt under försökets gång. Metanhalter analyserades med en gaskromatograf. Testerna avslutades efter 17 dagar eftersom produktionen för samtliga flaskor då hade upphört. Resultatet visar att samrötning av rödalger som hämtades i oktober med ymp genererade en högre metanpotential än andra substrat. Den högsta metangaspotentialen var 159 l/kg VS. Rödalger som inhämtades i januari genererade lägst metangaspotentialen, cirka 60 l/kg VS. Att samla upp tång och alger från stränder innebär många fördelar. Exempelvis att ta bort lukt, att öka rekreationsvärdet, att förbättra vattenkvaliteten, att minska övergödningen samt att stränderna blir mer badvänliga. Genom att framställa biogas från tång ökar dessutom produktionen av förnybar energi. Energin från biogas uppvisar mycket hög klimatprestanda och bidrar till en minskning av utsläpp av växthusgas.

Full textAbstract:
Despite a positive contribution to economic – social development, the growth of piggeries has caused heavily environmental pollution. Currently, treated wastewater of pig farms unfortunately does not meet the national discharge standards yet. This paper presents some research results on the removing COD, nitrogen and phosphorus in piggery wastewater after anaerobic (biogas) process at pilot scale by the combined system using Phragmites australis, Cyperus alternifolius, Vetiveria zizanioides and Eichhornia crassipes. The experimental results showed that the wastewater loading rate of 47.35 l/m2.day with initial concentrations of 203.24 mg COD/l, 111.94 mgTN/l and 13.61 mgTP/l gave removal efficiency of 71.66 %, 79.26 % and 69.65 %, respectively. Thus, the removed quantity of total nitrogen (TN) and total phosphorus (TP) was of 4201.35 mg TN/m2.day và 448.76mg TP/m2.day. The obtained results indicated that the flow wetland system, using Phragmites australis, Cyperus alternifolius, Vetiveria zizanioides and Eichhornia crassipes has a rather high COD, TN and TP removal efficiency with simple operation so that it could be feasible if applied for treating pig wastewater. However, the system should be functioned longer for taking data and for evaluating its stability.<br>Mặc dù có những đóng góp tích cực cho sự phát triển kinh tế - xã hội, việc phát triển chăn nuôi lợn đã gây ô nhiễm môi trường nghiêm trọng. Hiện nay, nước thải chăn nuôi lợn từ các cơ sở chăn nuôi sau xử lý vẫn chưa đáp ứng được các tiêu chuẩn thải của quốc gia và tiêu chuẩn ngành. Bài báo này trình bày kết quả nghiên cứu về khả năng loại bỏ COD, nitơ (N) và phôtpho (P) trong nước thải
chăn nuôi lợn đã qua xử lý bằng hầm biogas của hệ thống phối hợp cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây ở qui mô pilot. Kết quả thực nghiệm ở tải lượng 47,35 l/m2.ngày, với COD, tổng nitơ (TN) và tổng phôtpho (TP) đầu vào trung bình là 203,24 mg/l, 111,94 mg/l và 13,61 mg/l, tương ứng, thì hiệu suất xử lý lần lượt là 71,66 %; 79,26 % và 69,65 %. Như vậy lượng TN và TP loại bỏ là 4201,35 mgN/m2.ngày và 448,76 mgP/m2.ngày. Kết quả nhận được cho thấy hệ thống sử dụng cây Sậy, Thủy Trúc, cỏ Vetiver và Bèo Tây có hiệu quả loại bỏ COD, TN và TP khá cao trong khi vận hành đơn giản nên có triển vọng áp dụng trong điều kiện thực tế để xử lý nước thải chăn nuôi lợn. Tuy nhiên để đánh giá tính ổn định, hệ thống cần được hoạt động với thời gian lâu dài hơn.

Full textAbstract:
Biogas is a renewable resource which comes from numerous sources, such as biomass, manure, sewage, municipal waste, green waste and energy crops. It is a variable mixture of CH4, CO2, N2 and other gases. Ni-YSZ cermet is commonly used as the anode of a solid oxide fuel cell (SOFC) because it has excellent electrochemical performance and is cost effective. It can utilize not only hydrogen fuel, but also a clean synthesized biogas mixture of varying CH4 and CO2 concentrations with steam (H2O) and air (O2). However, trace impurities, such as H2S, Cl2, and F2 in biogas may cause degradation of cell performance. In this work, Ni-CeO2 coated Ni-YSZ anode-supported cells were exposed to two different compositions of synthesized biogases (biogas) with 100 ppm Cl2 under a constant current load at 850°C. The electrochemical performance was evaluated periodically using standard electrochemical methods. 20 ppm H2S impurity was also added to the fuel stream during the Cl2 impurity testing and its effect was noted. Post-mortem analyses of the SOFC anode were performed using XRD, SEM and XPS. The results show that Cl2 did not cause any electrochemical degradation of the cell during the 200 h test. However, after adding 20 ppm H2S, the cell started to degrade and eventually lost all its performance. The experimental data showed that 100 ppm Cl2 impurity in the fuel gas can postpone the degradation caused by addition of the H2S impurity.

Full textAbstract:
Biogas solutions in the Nordics is undergoing rapid developments and the demand for biogas is ever increasing because of the Russian war on Ukraine and the transition to fossil free industry and transportation. Furthermore, with the introduction of several multi-national companies into the biogas sector in the Nordics and with more and more biomethane being traded across national borders, it becomes increasingly important to view biogas solutions in the Nordics as a whole and to go beyond the confines of each individual nation. Since the transition and the current energy crisis require a quick response, understanding what could be done with current technologies and established substrates is important to guide decision-making in the short-term. This study aims to do just that by presenting the current biogas potential for the Nordics, including Denmark, Finland, Iceland, Norway, and Sweden. The potential was estimated for eight categories: food waste, manure, food industry waste, sludge from wastewater treatment, landscaping waste, straw, agricultural residues, and crops with negligible indirect land use effects (such as ley crops and intermediary crops). Two categories were excluded due to a lack of appropriate estimation procedures and time to develop such procedures, and these were marine substrates and forest industry waste. Furthermore, several categories are somewhat incomplete due to lack of data on the availability of substrates and their biogas characteristics. These include, for example, crops grown on Ecological focus areas, excess ley silage, damaged crops, and certain types of food industries. The specifics of each category is further detailed in Section 2 of the report. In the report, the biogas potential includes the biomethane potential, the nutrient potential, and the carbon dioxide production potential, capturing all outputs of a biogas plant. The results of the potential study show that the current biomethane potential for the Nordics is about 39 TWh (140 PJ) per year when considering the included biomass categories in the short-term perspective. In relation to current production, realizing this potential would mean a roughly fourfold increase in yearly production, meaning that a significant unexploited potential remains. On the nutrient side, the biogas system in the Nordics would, given the realization of the estimated potential, be of roughly the same size as current mineral fertilizer use (about 75 percent for nitrogen and 160 percent for phosphorous). While this represents the management of a significant portion of nutrients used in agriculture, the potential to replace or reduce mineral fertilizer use through biogas expansion remains unexplored in this study since a significant portion of nutrients come from biomass that is already used as fertilizer (e.g., manure). Finally, on the carbon dioxide side, about 4.2 million tonnes of carbon dioxide would be produced, which could be either captured and stored or captured and utilized, thereby further increasing the positive environmental effects associated with biogas solutions. In conclusion, there remains a large unexploited biogas potential in the Nordics, even when only considering current technologies and established feedstock that could be realized in the short-term (the theoretical potential is much larger since many substrate categories are excluded and the potential is limited to established technologies). Such a realization would bring large increases to biomethane production but would also mean that a significant amount of nutrients would be recirculated through the biogas system. This means that the biogas system has a key role to play in increasing both the food and energy security in the Nordic countries, in addition to its many positive environmental effects.

Full textAbstract:
arbon dioxide (CO₂) has a negative impact on the climate, but it also has several practical areas of use. Many industrial processes emit CO₂ in high concentrations, which could be captured to mitigate emissions while also creating valuable products. One example of such a process is biogas upgrading – a process separating renewable gases, where methane is taken care of for use as vehicle fuel or industrial energy carrier, while CO₂ is released into the atmosphere. The aim of this project has been to chart alternatives and technologies for taking care of green CO₂ from biogas upgrading, so-called carbon capture and utilization (CCU), and to investigate the conditions for applying these in a Swedish context. The work has been guided by the following research questions: * How large is the current and future potential for CCU from biogas production? * What are the possible areas of use for CO₂ from biogas production? * What factors influence the choice of areas of use for CO₂ from biogas production? * How large is the environmental benefit of CCU from biogas production? To answer these questions, calculations of potentials, a multi-criteria assessment and a life cycle assessment were carried out, based on the Swedish biogas production. A reference group comprising representatives for large Swedish companies within biogas production and biogas upgrading technology was used to enable coproduction and networking between the research group and the business sector. The production of CO₂ from biogas was estimated to 160,000 ton/year in 2020, with potential to increase to 540,000 – 840,000 ton/year in a few years and 790,000 – 1,230,000 ton/year in a longer perspective, as a consequence of an expected increase in the Swedish biogas production. A large share of the CO₂ is however produced at relatively small upgrading facilities, which could limit the feasibility for CCU due to high costs for investment and operation. Adding hydrogen to transform all the CO₂ into methane could potentially increase the methane production from biogas from 2 to 3 TWh/year in a short-term perspective and from 11 to 17 TWh/year in a long-term perspective, given sufficient access to hydrogen. Other ways of utilizing CO₂ from biogas include production of biomass or chemicals, concrete curing, pH control of process water and use as a refrigerant. The choice of CCU options can be influenced by environmental, technical, economic and policy-related aspects. From the biogas producers’ perspective, methanation is the option that is the most compatible with the existing production system and business model, while other solutions usually involve another actor taking care of the CO₂. Hydrogen is required for methanation as well as for production of chemicals. Another limiting factor are the high purity requirements on all CO₂ that is distributed and sold on the market. The geographical distribution of the production plants can also be a challenge. Several CCU options can improve the environmental performance of biogas by replacing fossil-based products. The potential climate impact is the lowest if the CO₂ is methanized with renewable hydrogen or mineralized in concrete, but other forms of environmental impact can also be reduced by applying these or other CCU options. For comparison, permanent storage of CO₂ in geological formations (carbon capture and storage, CCS) only reduces the climate impact, while it increases other forms of environmental impact. Furthermore, permanently storing biogenic CO₂ can make it difficult to reduce the use of fossil CO₂ and transition to a more sustainable society. The need for carbon in many essential processes and products suggests that biogenic CO₂ should be utilized and not stored.

Full textAbstract:
Addressing environmental challenges while improving social and economic conditions calls for innovative solutions. One of those challenges is the management of organic waste, which if left untreated can lead to water pollution, greenhouse gas emissions, and soil degradation. Brazil produces substantial amounts of organic waste due to its sizeable population and extensive agricultural production. As one of the largest economies in the Global South, the development of innovative solutions to organic waste management in Brazil can potentially pave the way for their adoption in other countries within the Global South. Biogas systems are solutions for organic waste treatment that simultaneously make use of the energy content, reduce gas emissions, and facilitate nutrient recycling. Nevertheless, their multifaceted nature also entails numerous barriers to their widespread implementation. Thus, this report explores the barriers to the development of biogas systems in Brazil and possible strategies to overcome these.Diverse data collection methods were used in the study. A literature review helped identified overall barriers to biogas systems development. This was followed by a field study in Brazil, involving visits to biogas facilities and interviews with stakeholders. The results were combined to understand the impact of the identified barriers across sectors. Finally, a workshop with Brazilian and Swedish stakeholders helped validate the findings and explore possible strategies to overcome barriers to biogas systems development.In the report barriers across eight categories are discussed, namely technological, economic, market, regulatory, cultural, environmental, network, and biomethane barriers. Technological barriers include lack of specialized knowledge, which leads to challenges in operation and maintenance of biogas reactors. Another type of technological barrier is limited access to infrastructure such as gas pipelines and sewage networks, which leads to technical challenges regarding both substrate supply and gas handling. High initial investments and funding accessibility are the most prominent economic barriers. Market barriers include competition with cheaper waste treatment solutions, lack of structured markets for biogas, and limited access to markets. The absence of a national biogas-specific policy, spatial diversity in state-level regulations; together with few and isolated incentives for biogas production are the major regulatory barriers. Cultural barriers include limited knowledge among society and substrate holders about biogas benefits, resistance to waste segregation practices, and sectoral structures hindering collaboration across the biogas value chain. Although environmental aspects of biogas systems are usually drivers to the implementation of biogas facilities, concerns such as gas leaks, odors, and soil contamination risks associated with poor facility design and performance are environmental barriers. Network barriers stem from limited platforms for discussion and interaction among actors, ultimately delaying the establishment of a unified national agenda for biogas development. Due to its characteristics, the production, distribution, and utilization of biomethane face additional challenges across various barrier categories, with major obstacles including uncertainties in grid injection contracts and infrastructure, as well as the expectation that biomethane prices should match those of natural gas.To overcome some of the barriers presented above, the study explored two strategies that could be pursued by actors interested in biogas systems development in Brazil. First, biogas cooperatives are proposed as one solution, allowing resource pooling for technology investment and enhanced biogas production. Second, dedicated biogas producers could play a crucial role,viparticularly in addressing financing challenges and ensuring efficient operation. Dedicated biogas producers could improve the technical efficiency and environmental performance of biogas facilities. Options for biogas utilization include electricity generation and biomethane production, with the latter offering tax benefits and reduced transportation costs when producers can use the biomethane for transportation themselves.The report highlights barriers across various dimensions and addresses strategies to overcome these barriers, such as biogas cooperatives and dedicated biogas producers. Future research could focus on testing these strategies in the Brazilian context through case studies, pilot projects, and collaborative initiatives to refine interventions and accelerate the adoption of biogas technologies.

Full textAbstract:
The project “Global dissemination of the Nordic model for biogas solutions”, referred to as IP4, aimed to create a decision-making guide for companies, municipalities, and researchers interested in internationalization of biogas solutions and create a platform for dialogue and sharing experiences. The project was operationalized through workshops, presentations by companies and researchers, focusing on the adaptability and sustainability of the Nordic Biogas Model (NBM) in international contexts. Three themes have been in focus and learning outcomes are summarized under each theme.Theme1: Conditions for successful adaptation of NBM Successful adaptation of the NBM internationally depends on context-specific factors, shaped by the local needs and socioeconomic conditions of the target country. The adaptation process is typically stepwise and gradual, with progress occurring incrementally in areas like policy, regulation, and technological advancement. It is also a reciprocal process, where mutual learning between providers and adopters is critical, supported by early-stage assessments to determine adopter readiness and key preconditions.Theme2: Sustainability implications of adapting NBM The NBM presents significant sustainability benefits through multi-valorisation, enabling value creation from biogas production, nutrient recycling, and system synergies such as industrial and urban symbiosis. However, the realization of these benefits depends on the local context, including effective policies and regulatory incentives (e.g., policies that discourage landfilling, or promote waste valorisation).Theme3: Lessons from international adaptation of NBM International experiences on adaptation of biogas solutions highlight that systems that fit and confirm to existing practices (e.g., landfilling organic waste with gas capture), offer some benefits with minimal changes in the sociotechnical system. In contrast, more systemic adaptations that are closer to NBM, provide broader and more lasting benefits that take time and requires structural adjustments.In summary, considering Themes 1–3, the successful adoption of the NBM in international markets requires a strategic and context-specific approach. It is crucial to clearly communicate the diverse sustainability benefits of the NBM early in the process, preventing a narrow focus on short-term gains. Also, technology providers need to adopt a systematic approach for assessing risks and opportunities at the early stages, considering the context-specific and diverse nature of international markets. Both adopters and providers should recognize that adapting the NBM involves navigating a complex landscape with coordination among stakeholders across sectors, each with its own regulations and market conditions. Thus, it is a gradual and time-consuming process.

Full textAbstract:
Since 2011, the influx of sargassum in the Caribbean and West Africa has posed significant socio-economic challenges. Despite these negative impacts, there is a growing effort to turn sargassum into an opportunity. This has led to the creation of innovative products and services made from sargassum, which are now being marketed both regionally and internationally. The "Sargassum Uses Guide" is the most comprehensive resource on the topic, providing an overview of current and potential uses, along with a directory of innovators and researchers. However, it does not assess the effectiveness of these solutions or provide a global outlook. This report offers a detailed update on the current landscape of sargassum innovation and governance. It introduces the "Sargometer," a proposed tool to help entrepreneurs evaluate the sustainability and effectiveness of different solutions. The study highlights case studies of leading innovators and their products, while also incorporating community perspectives on various technological solutions. The report concludes with considerations for the future development of the sargassum industry. Technological solutions for managing sargassum influxes in the Caribbean and Latin America primarily include machinery for onshore and in-water harvesting, as well as various by-products like compost, liquid extracts, bioplastics, biogas, construction materials, clothing, and cosmetics. Some products, such as biostimulants, biofertilizers, and compost, show high potential for short-term commercialization. To maximize the use of sargassum, the study suggests a biorefinery approach. As the industry grows, it is crucial to develop governance structures, including quality and regulatory frameworks, to ensure market success. Policies should also support sustainable sargassum businesses, such as duty-free concessions and free zones for equipment and property acquisition. With the right technology and supportive environment, even small enterprises can thrive internationally.
