Abstract:

Thailand, electricity production form biogas has been interested for replacement nuclear and fossil power plants. Current status of electricity production from biogas is 155 MWe, and more potential of current capacity is 380 MWe. Additional, energy crops have a potential for another source of biogas. For this study, electricity production to 1000 MW was determined. Napier grass was considered, high growth rate and high production yield. Napier grass 190,000 acre can produce 1000 MW electricity. And economic analysis of electricity production 1 MW was studied, these results show that biogas for electricity 1MW power plant project is not economic under current condition in Thailand.

Abstract:

Electricity is a pre-requisite for technological progress and economy growth. Thailand has been facing an electric energy crisis in inadequate electricity generation capacity compared with the demand. It is essential to replace the conventional energy (e.g. fossil fuels) and electricity import with renewable energy resources, particularly biogas that can be play a major role to meet the electricity demand. This paper explores the current state of biogas energy potential from livestock manures in Nakhonratchasima, Thailand. The results show a potential of electricity produced from animal manures of cattle, buffalo, swine and poultry. The total annual recoverable rates of livestock manures and biogas yield in Nakhonratchasima Province are 431.334 Mtonne of dry matter and 119,631 Mm3, respectively. In energy terms, the annual amount of the recoverable biogas resources is equivalent to 2,691.691 PJ or 748 TWh. This total amount of available biogas energy potential can meet anticipated electricity demand. Therefore, the assessment of biogas energy resources will make a significant utilization of energy management in the future.

Abstract:

Despite consisting of residual material in some processes, solid waste still presents huge potential for recycling, reuse, and energy use, either through thermochemistry or biochemistry. Municipal Solid Waste (MSW) can be energetically exploited by converting landfill gas (LFG) to electrical energy. In addition, animal manure can also undergo biodigestion, generating biogas that can also be harnessed energetically. Achieving economic viability is difficult when evaluating Thermal Power Plants (TPP) using biogas, especially in cases of smaller cities (in the case of LFG) or when animal populations (biodigestion) are smaller. This study presents three scenarios for electricity generation using biogas in a case study of a small city located in Itanhandu (MG), Brazil. This study sought to evaluate the benefits of using two sources for biogas production, these being LFG and the anaerobic digestion of henhouse manure. In the first scenario, a project generating electricity using LFG was analyzed. In the second scenario, energy was generated via biogas coming from manure collected at henhouses. The third scenario considered electricity generation from both sources. The results demonstrate that TPPs based only in LFG are not economically viable, while the other two scenarios present positive results as to their economic viability, showing that the biogas volume coming from manure collected at henhouses is sufficient for electricity generation at the TPP with landfill gas. This result could be beneficial both as a solution for Solid Waste Management (MSW) as well as providing an additional energy generation solution near to the city.

Abstract:

Due to the damage to the environment and climate caused by the generation of electricity in power plants burning fossil fuels, installations generating it from renewable energy sources are constructed. Spatial development plans for communes should consider their location. In Poland, generation of electricity in photovoltaic cells, wind farms and agricultural biogas plants has the greatest development potential. Due to the nuisance to people and the environment, wind turbines and agricultural biogas plants must be located far from residential buildings. Such conditions exist in sparsely populated rural areas. The observed development of single-family housing in rural areas is the result of the search for cheap construction sites and no local spatial development plans in most areas of rural communes. Dispersed housing construction restricts the construction of wind farms and agricultural biogas plants and thus poses a threat to renewable sources of wind and biogas energy produced in agricultural biogas plants. The situation may be changed by the requirement to include in spatial development plans the needs related to the construction of installations generating electricity from renewable energy sources and the construction of micro and small biogas plants directly at the sites where waste is generated.

Abstract:

Combined heat and power production from biogas is now playing an important role in energy and resource utilization as well as pollution control in waste water treatment. This research used biogas from the Bali Sewage Treatment Plant in New Taipei City, Taiwan, as a major source of fuel for the electricity generation. A micro gas turbine electricity generator, Capstone CR-30, which possesses a maximum rated power load (PWL) of 30 kW, was equipped to convert biogas into electricity. The biogas is mainly composed of CH4 (56.1 ± 8.0 vol.%), CO2 (25.5 ± 9.8 vol.%), H2 (0.5 vol.%), and H2S (0.99 ± 0.07 ppmv). During the test operation period of the generator, it was found that the thermal efficiency increases from 19.8% to 23.4% kWhe/kWhth, while the electricity generation efficiency (ηEB) also rises from 0.93 to 1.09 kWhe/m3 biogas as the PWL increases from 10 kW to 30 kW. The results indicated that the generator has a better performance with higher PWL. At PWL = 30 kW, the average adjusted concentrations of CO and NOx (adjusted to 15 vol.% O2) emitted from the generator are 86 ppmv and 17 ppmv, respectively. Both are much lower than the emission standards of stationary sources in Taiwan of 2000 ppmv and 150 ppmv, respectively. Thus, PWL of 30 kW was selected in cooperation with biogas inflow = 0.412 m3/min and air/fuel ratio (i.e., air/biogas ratio) = 76.0 vol./vol. for the long-term regular operation. At the above setting conditions for long-term operation, the generator continuously consumed the biogas and provided stable electricity generation at a rate of 19.64 kWhe/h for a 2-year running period. Moreover, the greenhouse gas can be cut off with a rate of 10.78 kg CO2e/h when using biogas as fuel for electricity generation. Overall, this research proves that the application of a micro gas turbine electricity generator not only has promising performance for using biogas but also gives a significant reduction of greenhouse gas emission, which fits the concepts of the circular economy and environmental protection.

Abstract:

This paper presented a biogas-solar hybrid system and investigated the feasibility of using biogas to increase the enthalpy of parabolic trough collectors steam so as to increase the cycle efficiency and power production. High temperature anaerobic digestion (AD) was adopted to produce biogas by using corn straw, manure and sewage. Biogas fraction and energy-to-electricity efficiency were used to evaluate the biogas contribution to the electricity generation and the energy utilization efficiency based on off-design performance analysis respectively. A comprehensive levelized electricity cost (LEC) and life cycle assessment (LCA) for the hybrid system power production were performed. The simulation calculation results show that biogas utilization plays an important role in the decrease in systemic LEC and greenhouse gas emissions. Improvement is achieved in both of generation cost and greenhouse emissions for biogas-solar hybrid plant compared to solar-only plant.

Abstract:

The paper analyzes the energy potential of autonomous power supply based on renewable energy sources in a livestock farm. Based on calculations of the amount of farm waste that act as raw materials for a biogas power plant, the amount of electricity that can be produced from biogas has been determined. The value of electricity generation was also determined when a biogas plant and solar panels are used together in order to fully cover the need for electricity. It has been established that the use of renewable energy sources for autonomous power supply has significant potential for growth, in particular, the generation of electricity by a biogas power plant is calculated according to the minimum indicators for a cattle farm, provides 57% of the required electricity, in addition, there is also thermal energy, which is used for heating farms. The combined operation of the biogas plant and solar panels installed on the roof of the farm allows to cover the need for electricity with a reduction factor of 2.6 solar panels generation. The use of biogas obtained from the waste of a cattle farm and together with solar panels makes it possible to cover the need for electricity with a significant reserve. For a typical farm of 100 cattle, this stock is about 80%. The use of which is possible with the use of energy storage devices and the formation of a biogas reserve. It has been established that the electrical power of a biogas plant, which works in conjunction with solar panels, should be at least the average value of the power consumption to provide autonomous power supply to consumers of the livestock farm, especially in the winter months when solar insolation is minimal.

Abstract:

Demand-oriented power generation by power plants is becoming increasingly important due to the rising share of intermittent power sources in the energy system. Biogas plants can contribute to electricity grid stability through flexible power generation. This work involved conducting an economic and global warming potential (GWP) assessment of power generation with biogas plants that focused on the Austrian biogas sector. Twelve biogas plant configurations with electric rated outputs ranging from 150–750 kW and different input material compositions were investigated. The results from the economic assessment reveal that the required additional payment (premium) to make power generation economically viable ranges from 158.1–217.3 € MWh−1. Further, the GWP of biogas plant setups was analyzed using life cycle assessment. The results range from −0.42 to 0.06 t CO2 eq. MWh−1 and show that the 150 kW plant configurations yield the best outcome regarding GWP. Electricity from biogas in all scenarios outperformed the compared conventional electricity sources within the GWP. Greenhouse gas (GHG) mitigation costs were calculated by relating the needed premium to the CO2 eq. saving potential and range from 149.5–674.1 € (t CO2 eq.)−1.

Abstract:

The limitations of conventional energy resources have encouraged worldwide research on various types of energy in electricity generation. Fuel cell-based electricity generation creates a huge potential in the energy industry. This paper aimed to study the potential of biogas in Malaysia to be fed into the direct biogas solid oxide fuel cell (DB-SOFC) system. The data obtained from the Malaysian Palm Oil Board (MPOB), Energy Commission (ST) and Department of Statistics Malaysia were used in this study. The analysis showed that in 2019, Malaysia had the potential to generate biogas of about 877.53 million m3/year. The characterisations of the DB-SOFC system with a capacity of 200 kW from Bloom Energy were applied in this study. The result indicated that Malaysia’s potential to generate about 2006.9 MW of electricity from biogas solid oxide fuel cells was approximately 6% of the total electricity capacity in the country. When compared with the conventional biogas’ combined production of heat and power (CHP), the DB-SOFC gave 76.95% more performance in electricity generation. Therefore, this study finding provides a positive impact on the biomass industry in Malaysia. Extensive research and development (R&D) are needed in order to penetrate this fuel cell system into Malaysia’s energy industry landscape.

Abstract:

This work assessed the energy potential and alternative usages of biogas and sludge generated in upflow anaerobic sludge blanket reactors at the Laboreaux sewage treatment plant (STP), Brazil. Two scenarios were considered: (i) priority use of biogas for the thermal drying of dehydrated sludge and the use of the excess biogas for electricity generation in an ICE (internal combustion engine); and (ii) priority use of biogas for electricity generation and the use of the heat of the engine exhaust gases for the thermal drying of the sludge. Scenario 1 showed that the electricity generated is able to supply 22.2% of the STP power demand, but the thermal drying process enables a greater reduction or even elimination of the final volume of sludge to be disposed. In Scenario 2, the electricity generated is able to supply 57.6% of the STP power demand; however, the heat in the exhaust gases is not enough to dry the total amount of dehydrated sludge.

Abstract:

Biogas, a renewable energy source, is generated from biomass under anaerobic treatment. Anaerobic treatment of biomass occurs within a vessel – also known as a digester – that is fully sealed off from air and usually has naturally occurring bacteria to allow digestion and the production of biogas. The objective of this study was to investigate the potential of generating electrical energy from digester carbon waste sources. A GIZ/WEC model was utilized together with other WWTPa-based parameters to calculate the potential electricity that could be generated daily in two plants (Vlakplaats and Waterval), and the size of combined heat and power (CHP) suitable for the WWTPs was also identified. In terms of gaseous composition, four components were found in the biogas with CH4 and CO2 being the main constituents, having concentrations between 30%-38% and 62%-70% for CO2 and CH4, respectively. The electricity generated was on average 3 861 kWeh/day for the Vlakplaats plant and 21 777 kWeh/day for Waterval. Overall, the generation of electricity through the use of biogas is achievable, primarily when the amount of biogas produced on a daily basis reaches or exceeds the estimated biogas usage. The results obtained from this analysis showed estimate efficacy and consistency in the amount of electricity that can be generated.

Abstract:

Small-scale electrical power generation (<100 kW) from biogas plants to provide off-grid electricity is of growing interest. Currently, gas engines are used to meet this demand. Alternatively, more efficient small-scale solid oxide fuel cells (SOFCs) can be used to enhance electricity generation from small-scale biogas plants. Most electricity generators require a constant gas supply and high gas quality in terms of absence of impurities like H2S. Therefore, to efficiently use the biogas from existing decentralized anaerobic digesters for electricity production, higher quality and stable biogas flow must be guaranteed. The installation of a biogas upgrading and buffer system could be considered; however, the cost implication could be high at a small scale as compared to locally available alternatives such as co-digestion and improved digester operation. Therefore, this study initially describes relevant literature related to feedstock pre-treatment, co-digestion and user operational practices of small-scale digesters, which theoretically could lead to major improvements of anaerobic digestion process efficiency. The theoretical preamble is then coupled to the results of a field study, which demonstrated that many locally available resources and user practices constitute frugal innovations with potential to improve biogas quality and digester performance in off-grid settings.

Abstract:

Biogas represents a promising source for the production of clean energy. The objective of this paper was to quantify the potential for the reduction of emissions to the environment during the production of electricity from biogas in comparison with environmental effects of the production of the same amount of electricity from fossil resources (coal from Kolubara basin and natural gas). Basis for comparison of environmental impacts in this work was the annual production of electricity in biogas plants of the total capacity of 80 MW. This study has shown that the annual production of electricity from biogas power plants of 80 MW results in: substitution of up to 840 kt of coal from Kolubara basin and 123.2 million m3 of natural gas; reduction in emissions of greenhouse gases in the range of 491.16 kt - 604.97 kt CO2-eq, depending on the energy efficiency of the process of electricity production from biogas; reduction in emissions of greenhouse gases up to 92.37 kt CO2-eq compared to the use of natural gas for electricity generation.

Abstract:

This work evaluates the biogas production potential of the Ceibales landfill for feeding a power plant in the southern region of Ecuador. Biogas production is estimated through mathematical models that consider energy generation and technologies available to supply electricity plants. Characteristic landfill data are accounted for to analyze and develop these mathematical models. Once the generation capability of each source is identified, a decision can be made on the most suitable electricity generation technology. A local model (Ecuadorian model) is applied to calculate the potential of biogas and is compared with other models commonly used for evaluating this type of project. This type of renewable energy is attractive because it produces electricity from waste; however, it is not an attractive option unless its application is encouraged, as hydro has been encouraged through the investment of taxpayer resources. Technologies require a boost to become profitable, and even more so if they compete with traditional technologies.

Abstract:

The focus of this is to make available clean energy, where there is a need for electricity production or energy infrastructure. An anaerobic digester contains an oxygen free environment that allows microorganisms to break down the organic material to harvest biogas (methane). Once the biogas is formed it can be used for different applications to aid the developing world. There are already millions of biogas plants in operation throughout the world. In Germany and other industrialized countries, power generation is the main purpose of biogas plants; conversion of biogas to electricity has become a standard technology. Biomass can become a reliable and renewable local energy source to replace conventional fossil fuels in local industries and to reduce reliance on overloaded electricity grids. The concept presented is to use manure from farms to produce methane gas using anaerobic digestion.

Biogas power generation is renewable energy made from biological materials. Biogas power production is technology which helps in development of sustainable energy supply systems. This paper develops Genetic Algorithm optimization model for Biogas electrical power generation of Ilora in Oyo, Oyo state. The production is done using co-digestion system of pig dung and Poultry dung under the process of anaerobic digestion. The pig dung and poultry dung were mixed 50:50%. MATLAB and VISUAL BASIC Software was used to carry out simulations to develop optimized Genetic Algorithm model for Biogas power production with aims to improving electricity accessibility and durability of the community. The results of the research reveal the Empirical Biogas power production without and with Genetic Algorithm optimization. The Result showed that biogas electrical power generated without and with Genetic Algorithm Optimization were 5KW and 11.18KW respectively. The biogas power generation was increased by 6.18KW, which is 38.2% increase after Genetic Algorithm optimization. The results show the application of the Genetic Algorithm optimization model which can be used to improving Biogas power generation when amount of methane gas produced from the animal dung varies with speed of thermal rotating shaft.

We incorporate risk into simulation models representing dairy farms in Texas and demonstrate the profitability of new anaerobic digester installation. Based on this market, results indicate projects that have low investment costs, receive grant support for construction, utilize coproducts, or have some combination of these factors have higher net present value at the end of the study period; however, even with generous grant support and high electricity prices, projects with average investment costs remain unprofitable.

Abstract:

The population increase and the food demand increase the fight against climate change. Porcine production in Europe continues to increase, and Spain is the leading country in pig production. Manure management has a significant environmental impact that requires anaerobic digestion technologies for its mitigation. This technology helps produce biogas, a fuel that will reduce CO2 emissions. This study defines a distributed biogas generation model, determining the expected incomes from the development of this technology in small manure generation facilities (digestible organic waste). The development of this technology will contribute to reduce the demand for fossil energy and increase revenues by 22.7% regarding the expected revenues from the use of biogas for electricity generation.

Abstract:

The future of Australia’s electricity industry has resulted in significant debate about the mix of electricity generating technologies. The Finkel Review and ensuing National Electricity Guarantee policy discussion have revealed divisions between key stakeholders over the future generating mix between renewable and fossil fuel power generation options. A portfolio of technologies will be required, including the need for gas-fired power generation with and without carbon capture and storage (CCS), to provide dispatchable synchronous electricity. Gas Vision 2050 has stated that CCS, along with biogas and hydrogen, will be one of the three transformational technologies affecting the gas industry going forward. Through the use of a techno-economic model, the costs for a hypothetical new-build gas-fired power plant in the Hunter Valley with and without CCS were estimated. The model is cross referenced with other authoritative publications including the CO2CRC Australian Power Generation Technology Report. The model considers the base-case scenario and sensitivity analysis of key cost drivers such as the domestic gas price and labour. The results of the model will enable key energy and gas industry stakeholders to make informed decisions about the vital role of gas as a power generation technology in Australia to deliver dispatchable synchronous electricity in a carbon constrained environment.

Abstract:

Brazilian cattle raising needs greater automation as a way to improve productivity and at the same time new ways to meet the growing energy demand. Thus, an alternative is to use renewable sources of electric energy such as biogas. This work proposes a methodology for economic evaluation of the externality denominated emissions, originating from the generation of electric energy through the burning of biogas from residues of Brazilian livestock. Thus, an equation was proposed and applied to obtain the value of this externality as a percentage of the value of electric energy, where greater results indicate greater potential for this externality. The results showed that the emissions, assessed as an externality and quantified on the basis of carbon credits can account for up to 69.4% of the electricity price, but if quantified in relation to the social impact of carbon, the externality in reference exceeds the value of electricity, reaching 408.4%. As a result, it is clear that the use of biogas for power generation in livestock can present other valuable products in addition to electricity and, consequently, can add value to livestock activity.

Abstract:

One hectare of coconut land (156 palms ha-1) planted with gliricidia (2250 trees ha-1 into double rows in avenues of coconut), available natural pasture and outside supplied paddy straw coupled with six buffaloes were mixed into a farming model to examine total productivity and potential of green energy production by wood and biogas. Six buffaloes were maintained in a shed and the manure was collected for biogas generation. Biogas was purified from H2S and the bio fuel was used to run a 0.75 hp engine. Wood of gliricidia was used to energize a 3.5 kW gassifire-engine system for generating electricity. Productivity of gliricidia in the 3rd year was 4.5 kg wood (at 20% moisture) and 3.5 kg of fresh foliage per tree/year. Each buffalo produced an average of 622 liters of milk at the first lactation (for a period of 10 months) and value of a calf was Rs. 41244.00 at the age of 17 months. Soils of the model were enriched by adding the effluent of biogas digester. The soil fertility (N, P, K, Mg, moisture holding capacity) improved significantly over soils sampled outside the model. The effluent of biogas was more fertile than dried buffalo dung. As a result, nut yield of coconut palms increased from 30 to 60 nuts palm-1 year-1 over a period of two years. In green energy production, the dung of six buffaloes passed through a 0.5 kW biogas-engine system generator produced 2 kwh of electricity per day which if generated by diesel driven generator would require 0.9 liters of diesel. The annual generation of electricity from the biogas amounted to 700 kwh. On the other hand, gliricidia wood of one hectare of coconut land was sufficient to energize 3.5 kW gassifire – engine – generator set for 1600 hours/year and this was equivalent to 5000 kwh of electricity (kWh). Thus, one hectare of coconut/gliricidia/natural pasture/paddy straw with six buffaloes was able to produce green energy equivalent to 5700 units of electricity (kWh) or 2,565 liters of diesel, in addition to farm income derived from coconut, buffalo milk and other benefits of buffalo farming. The total return (coconut, selling of calves, buffalo milk and bio fertilizer) added up to Rs. 704,070 ha-1 year-1. The feasibility of this model for adoption by small farmers of the coconut triangle in Sri Lanka is presented on the basis of this study.

Abstract:

Biogas is considered as a gaseous tributary of the anaerobic digestion of agro-industrial waste, a boiler, it can be burned in combustion engines to generate electricity and heat through cogeneration. Biodigesters responsible for producing energy with a content of 1 m3 of biogas (60% CH4 and 40% CO2) equivalent to 6 kWh / m3. It undergoes a purification its composition will depend not only on the technology used for the process but also on the treated substrate. Its methane composition varies between 50 and 70% and present between 30 and 40% CO2 and less than 5% hydrogen (H2) and other gases. The calorific value of biogas is associated with the composition of the methane it has. Biogas is a very versatile source of energy, it can be transformed into thermal energy through the use of process eliminating hydrogen sulfide and other contaminants from the membranes, it can be used as fuel, purifying and adding the necessary additives, it can be transformed into biomethane, a compound with characteristics very similar to natural gas. Biogas can be used as an electricity generator or as a heat producer if both sources of energy are generated, we speak of a cogeneration process, the electricity produced by generation can be injected into the electricity grid or consumed by the industry that generates the waste.

Abstract:

Wastewater treatment plants use energy intensive processes for removing pollutants, consuming large amounts of electricity and emitting greenhouse gases. The possibility of zeroing carbon emissions due to energy use in these plants has been investigated in the current work with reference to the municipal treatment plant of Chania on the island of Crete, Greece. The sewage treatment plant processes 19,400 M3 daily consuming 0.543 KWh per M3 or 3840 MWh annually. The use of locally available renewable energies has been proposed for electricity generation combined with co-generation of heat and power from the biogas already produced in the plant with sludge digestion. Installation of solar-PV systems and wind turbines in the plant could generate electricity, each equal to 25 % of the annual electricity consumption in the plant. Additionally, biogas use can cover all the heating needs in the plant and can generate electricity corresponding at 20% of the total annual grid electricity use. Creation of a tree plantation, irrigated by the treated effluent, of 118.4 hectares, has been proposed which could annually offset carbon emissions due to the remaining grid electricity use. Creation of the tree plantation will create additional benefits, due to existing land desertification in Crete, additionally to carbon sequestration. The size of the required solar-PV and wind turbine systems has been estimated at 640 KWp and 391 KW and their cost at 0.832 mil € and 0.430 mil € correspondingly. Current work indicates that the combined use of solar energy, wind energy, biogas and carbon sequestration with tree plantations could zero carbon emissions in the municipal sewage treatment plant of Chania, Crete.

AbstractThe Renewable-Energy-Source-Act (EEG) promotes German biogas production in order to substitute fossil fuels, protect the environment and prevent climate change. In this paper we quantitatively analyse the EEG-reform in 2008. Results imply that the reform contributes to an expansion of biogas electricity generation and thus to substitution of fossil fuels. However, subsidies, land and transport emissions per unit of electricity produced increase. An alternative analysis shows that an EEG with tariffs independent from plant-types would provide the highest subsidy-efficiency, lower land requirements and higher transport emissions compared to EEG before its reformation.

Abstract:

The work reported in this paper investigated the potentials of commercial biogas production from biodegradable waste in Benin metropolis. The study was carried out in two phases. The first phase involved characterization of solid waste generated and determination of the quantity of potential feed stock for biogas production in Benin metropolis and the second phase was determination of the amount of biogas obtainable from biodegradable waste. The results from the study showed that an average daily generation rate of 0.358kg per person per day (ppd.) of solid waste is generated in study area. Food waste accounted for about 78.49% of the generated solid waste representing 0.281kg per person per day (ppd.) and a total daily food waste generation of 305.075tonnes. Based on this value for food waste the obtainable biogas was estimated to be 28,836.91m3 of biogas in Benin metropolis per day. This volume of biogas can provide cooking gas for about 24,076.91 families per month in Benin metropolis or alternatively can be utilised to generate about 49.023MW of electricity per day.Keywords: Solid waste management, food waste, anaerobic digestion, biogas

Abstract:

This study aimed to map and estimate the potential of electricity generation from biogas produced through the anaerobic digestion process of vinasse in the state of Minas Gerais, Brazil, focusing on the energy use of an electric powered otto cyclemotor generator set. The potential for electric power generation was estimated from the amount of sugarcane produced in the 2018/2019 harvest in each municipality of the State. Then, the map was made with the spatialization of the information, in order to denote the municipal potentialities of the regions with the highest available energy indices. Energy availability was in the order of 746.43 GWh for each sugarcane crop, being more concentrated in the Triangulo Mineiro Region. Therefore, the use of this biomass waste into the anaerobic digestion process to produce electricity from biogas represents an environmental solution, an economical alternative and a social benefit.

Abstract:

Pakistan is facing a severe energy crisis due to its heavy dependency on the import of costly fossil fuels, which ultimately leads to expansive electricity generation, a low power supply, and interruptive load shedding. In this regard, the utilization of available renewable energy resources within the country for production of electricity can lessen this energy crisis. Livestock waste/manure is considered the most renewable and abundant material for biogas generation. Pakistan is primarily an agricultural country, and livestock is widely kept by the farming community, in order to meet their needs. According to the 2016–2018 data on the livestock population, poultry held the largest share at 45.8%, followed by buffaloes (20.6%), cattle (12.7%), goats (10.8%), sheep (8.4%), asses (1.3%), camels (0.25%), horses (0.1%), and mules (0.05%). Different animals produce different amounts of manure, based upon their size, weight, age, feed, and type. The most manure is produced by cattle (10–20 kg/day), while poultry produce the least (0.08–0.1 kg/day). Large quantities of livestock manure are produced from each province of Pakistan; Punjab province was the highest contributor (51%) of livestock manure in 2018. The potential livestock manure production in Pakistan was 417.3 million tons (Mt) in 2018, from which 26,871.35 million m3 of biogas could be generated—with a production potential of 492.6 petajoules (PJ) of heat energy and 5521.5 MW of electricity. Due to its favorable conditions for biodigester technologies, and through the appropriate development of anaerobic digestion, the currently prevailing energy crises in Pakistan could be eliminated.

Abstract:

Abundant of palm oil waste creates huge potential in producing biogas. Technically, biogas can be fed as an input gas into the fuel cell system to get the electricity output. This paper aims to estimate the life cycle costs and environmental impact for the biogas feed to the solid oxide fuel cell system in two different models: Individual System and Centralized System. Then the system boundary-setting starts from palm oil plantation until the fuel cell system. The result indicates that the individual system is more efficient due to lower cost and emission compared to the centralized system. Life cycle cost for the individual and centralized system is RM 2.56 / kWh and RM 7.04 / kWh, respectively. Then the carbon dioxide emissions are 0.2034 CO2-EQ / kWh and 0.61 CO2-EQ / kWh. Hopefully, the outcome from this paper will be able to assist the decision-maker in planning to model the fuel cell combining with biogas system in the future. Apart from that, its objective is to focus on cost-efficient and more sustainable electricity generation.

Abstract:

Biogas is currently produced in Crete-Greece from the two existing landfills in the island, as well as from the sewage treatment plants in Chania and Heraklion. Biogas produced in the two treatment plants is already used for co-generation of heat and power. However, since the quantities of landfills biogas and its energy content are significant, it can be used in the future either for heat production or for heat and power generation. Generated power can be fed into the grid and the produced heat can be used from a heat consumer. Since large heat consumers are not located nearby the existing landfills, there is the possibility for the creation of agricultural greenhouses in the surrounding agricultural areas which can utilize the generated heat. Landfill in Heraklion has an average biogas production of 1.43x107 NM3/year, almost five times higher than the landfill in Chania and the totally recoverable biogas from the two landfills can generate 16.73 GWh/year of electricity, in the case of a CHP plant, and enough heat for heating 15.4 hectares of modern greenhouses. In the case of direct heat generation, recoverable landfill biogas can heat 24.41 hectares of modern greenhouses. Since the global warming potential of methane is much higher than CO2, energy exploitation of landfills biogas in Crete will result in environmental benefits compared with its direct emission to the atmosphere.

Abstract:

The agriculture and livestock industry generate waste used in anaerobic digestion to produce biogas containing methane (CH4), useful in the generation of electricity and heat. However, although biogas is mainly composed of CH4 (~65%) and CO2 (~34%), among the 1% of other compounds present is hydrogen sulphide (H2S) which deteriorates engines and power generation fuel cells that use biogas, generating a foul smell and contaminating the environment. As a solution to this, anoxic biofiltration, specifically with biotrickling filters (BTFs), stands out in terms of the elimination of H2S as it is cost-effective, efficient, and more environmentally friendly than chemical solutions. Research on the topic is uneven in terms of presenting performance markers, underestimating many microbiological indicators. Research from the last decade was analyzed (2010–2020), demonstrating that only 56% of the reviewed publications did not report microbiological analysis related to sulphur oxidising bacteria (SOB), the most important microbial group in desulphurisation BTFs. This exposes fundamental deficiencies within this type of research and difficulties in comparing performance between research works. In this review, traditional and microbiological performance markers of anoxic biofiltration to remove H2S are described. Additionally, an analysis to assess the efficiency of anoxic BTFs for biogas desulphurisation is proposed in order to have a complete and uniform assessment for research in this field.

Abstract:

Concerns about biogas from landfills are reviewed in terms of biogas generation, composition, and elimination. Biogas is mainly composed of methane and carbon dioxide but it also contains a few hundred non-methane organic compounds. The solutions available to reduce its harmful effects on the environment and on human health are valorization as electricity or heat, flaring, or biofiltration. The main parameters affecting the biofiltration of methane are reviewed: temperature, moisture content, properties of the packing material, nutrient supply, oxygen requirements, formation of exopolysaccharides, and gas residence time. An analysis is performed on the co-metabolic properties and the inhibition interactions of the methane-degrading bacteria, methanotrophs.

Abstract:

With the application and promotion of large-scale biogas project, economic analysis and evaluation of large-scale biogas project are particularly important. However, the benefits of biogas project embodied in the economic, social, ecological, and many other aspects have dispersion, which leads to production decisions in a gray state and investment in conformity. In this paper, Great Northern Wilderness beef cattle industry in Heilongjiang province is taken as an example for large-scale biogas electricity generation project. The supply and demand of funds in project operation are analyzed quantitatively by using system dynamics theory so as to do study and perform optimal analysis comprehensively on the economics of biogas project, and to explore the effective scheme of improving the proportion of income against cost. This study can provide scientific guidance for evaluating the construction and operation of large and medium-scale biogas project objectively and lay a solid theoretical foundation for the commercial operation in biogas industry.

Abstract:

The purpose of this study was to investigate whether biogas technology could provide a school with an acceptable, affordable, efficient and sustainable alternative energy resource, thereby providing opportunities for cost savings, income generation and greater opportunities for education. The school selected for this study was Myeka High School, situated in rural Maphephetheni village, KwaZuluNatal. The school was not connected to grid electricity and was using solar PV energy and LP gas to support its energy needs. A floating dome biogas system, which operated on human excreta and cow dung, was donated to the school to supplement the school’s energy needs. Data was collected using both qualitative and quantitative techniques. Results revealed that the biogas was an acceptable source of energy because the school used the biogas for cooking and refrigeration. However, it was not affordable as savings on energy expenditure of the school could not offset the original cost of the biogas system unless a capital subsidy is applied. The long-term benefits on the educational environment cannot be underestimated. Biogas energy was found to be both efficient and sustainable, provided proper management was in place. In spite of this, findings indicated a lack of appreciation of how the system functioned by teachers and students; the need for more thorough and ongoing education of users before and after installation; the need for robust toilets and washbasins; and on the difficulties in getting the system fully operational in the limited time span for evaluation. Although income generation opportunities through biogas were not utilised at the school, there was an opportunity for income generation through biogas generation, provided there was encouragement, support and markets available.
