Abstract:

Wood and agricultural biomass pellets boost the potential as bio-fuels toward power production in tertiary and residential sectors. The production of pellets, however, is a multi-stage process where the supply-processing phases and the overall energy input strongly depend on the characteristics of the input biomass. In this paper, we describe the key features of the market for pellets in Italy, including national production and consumption data, production costs and prices, the available energy conversion systems, and the current regulatory issues. Moreover, we outline the main technical, economic, and end-user barriers that should be addressed in order to foster the growth of Italian pellet production. Additionally, we propose a methodology to evaluate the profitability of the pellet production chain, by assessing the investment and operation costs as a function of the quality of the raw biomass. The approach is applied to a real case study of a small firm producing wooden frames along with dry wood chips as the main by-product, which can be utilized subsequently for pellet production. Moreover, in order to optimize the size of the pellet production plant, further biomass was purchased from the market, including wood pruning and agricultural residues, wood chips from forestry, and uncontaminated residues of wood processing firms. A sensitivity analysis of the main technical and economic parameters (including the cost and quality of raw material, pellet market value, investment and operational costs, and plant lifetime) indicated that the biomass market price considerably affects the profitability of pellet production plants, particularly where the biomass has a high moisture content. Therefore, a 20% increase in the price of biomass with a high moisture content leads to a 60% fall in profitability index, turning it into negative one. This is due in particular to the costs of pre-treatment and drying of biomass, as well as to the lower energy content of wet biomass. As a result, the use of forestry residues with high moisture and high ash content, high costs of collection/transport, and high costs of pre-treatment and drying is not financially competitive.

Abstract:

After the recent economic crises, a necessity for industrial policy developing became obvious both for developed and developing countries. In 2014 Russia adopted a Fundamental federal law on industrial policy, but there are however a number of problems to be solved, such as an assessment of the impact of the implementation of industrial policy alternatives. In the author's opinion, the solution of these problems can be based on the concept of techno-economic paradigm shift. Using the correlation and regression analysis, the dependence of GDP on the development of high-tech industries was studied on the example of technologically advanced countries (USA, China, and Japan) and also Russia. The study was conducted in the absence of developed tools and limited statistics which could provide an indirect basis for assessing the impact of techno-economic paradigm on economic growth and well-being of the population. The author concludes that of the three examined indicators, the high-tech export is the most representative. It can thus be recommended as one of the criteria for assessing impact evaluations of the implementation of industrial policy, which can meet the challenges of scientific and technological progress at the shift of techno-economic paradigms.

Abstract:

We describe the elements and actors in the global natural gas value chains with an emphasis on characteristics relevant for large-scale energy system and market modeling. We give backgrounds on natural gas as a hydrocarbon to provide a rationale and understanding for what functional representations in mathematical programming models aim to represent. Simply taking the most advanced and detailed functional forms for all value chain characteristics and activities will typically result in numerical intractability. One should carefully determine what is needed to address a research question or analyze a business case. Recent advances in mathematical programming do allow solving large models with adequate detail for many types of analysis. We discuss which functional forms and modeling approaches can be appropriate for representing various characteristics in different types of analysis and provide a succinct and general mathematical programming formulation reflecting the optimization problems for different types of actors in the value chain. We provide an implementation for a stylized network using GAMS.

Abstract:

Purpose In 2008, a number of Southern African countries cultivated about 900,000 ha of Jatropha, with a number of biodiesel plants ready for production; however, none of the projects succeeded. In 2014, KiOR advanced biofuel Energy Company in the USA announced bankruptcy due to incompetent technology. Studies disclose that the reasons for biofuel plants failure are not only due to lack of incentives and unclear policies but also due to lack of economic feasibility and low production yields. This paper aims to review the techno-economy assessment of second-generation biofuel technologies. The purpose of this paper is to summarize specific techno-economic indicators such as production cost, technology efficiency and process life cycle analysis for advanced biofuel technology and to narrate and illustrate a clear view of what requires assessment to deploy a feasible advanced biofuel technology. This study also reviews assessment of biomass supply chain, feedstock availability and site selection criteria. The review also elaborates on the use of different processes, forecasting and simulation-modeling tools used in different techno-economic analysis studies. The review provides guidance for conducting a technical and economic feasibility study for the advanced biofuels energy business. Design/methodology/approach The aim of this review is, therefore, to evaluate the techno-economic feasibility studies for the establishment of viable industrial scale production of second-generation biofuels. It does so by grouping studies based on technology selection, feedstock availability and suitability, process simulation and economies as well as technology environmental impact assessment. Findings In conclusion, techno-economic analysis tools offer researchers insight in terms of where their research and development should focus, to attain the most significant enhancement for the economics of a technology. The study patterns within the scope of techno-economics of advanced biofuel reveal that there is no generic answer as to which technology would be feasible at a commercial scale. It is therefore important to keep in mind that models can only simplify and give a simulation of reality to a certain extent. Nevertheless, reviewed studies do not reach the same results, but some results are logically similar. Originality/value The originality of this article specifically illustrates important technical and economic indicators that should be considered when conducting feasibility studies for advance biofuels.

Abstract:

The world’s challenge is to determine a more efficient, economical and environmental-friendly energy source to compete and replace the ongoing conventional energy resources. Solid oxide fuel cells (SOFCs) provide a highly efficient system to use divergent energy resources and have proved to provide the cleanest energy, least energy use, and lowest emissions. A techno-economic study is required to investigate the model design for SOFC-based micro-combined heat and power (m-CHP) systems for applications in terms of educational and commercial buildings. This work models and explores the optimized application of hydrogen gas-fueled SOFC-based m-CHP systems in educational buildings. Two educational departments’ loads are presented and model of SOFC-based m-CHP system against the different electric power demands is performed, in order to provide a techno-economic assessment of the technology. For successful development of the technology, results are related to system rightsizing, operating strategies, thermal to electric ratios, and match between end-use, with an aim towards classifying the overall feasibility and essential application requirements.

Abstract:

Underground coal gasification (UCG) enables utilization of coal reserves, currently not economically exploitable due to complex geological boundary conditions. Hereby, UCG produces a high-calorific synthesis gas that can be used for generation of electricity, fuels, and chemical feedstock. The present study aims to identify economically-competitive, site-specific end-use options for onshore- and offshore-produced UCG synthesis gas, taking into account the capture and storage (CCS) and/or utilization (CCU) of produced CO 2 . Modeling results show that boundary conditions favoring electricity, methanol, and ammonia production expose low costs for air separation, low compression power requirements, and appropriate shares of H 2 /N 2 . Hereby, a gasification agent ratio of more than 30% oxygen by volume is not favorable from the economic and CO 2 mitigation viewpoints. Compared to the costs of an offshore platform with its technical equipment, offshore drilling costs are marginal. Thus, uncertainties related to parameters influenced by drilling costs are negligible. In summary, techno-economic process modeling results reveal that air-blown gasification scenarios are the most cost-effective ones, while offshore UCG-CCS/CCU scenarios are up to 1.7 times more expensive than the related onshore processes. Hereby, all investigated onshore scenarios except from ammonia production under the assumed worst-case conditions are competitive on the European market.

Abstract:

Diesel generators are currently used as an off-grid solution for backup power, but this causes CO2 and GHG emissions, noise emissions, and the negative effects of the volatile diesel market influencing operating costs. Green hydrogen production, by means of water electrolysis, has been proposed as a feasible solution to fill the gaps between demand and production, the main handicaps of using exclusively renewable energy in isolated applications. This manuscript presents a business case of an off-grid hydrogen production by electrolysis applied to the electrification of isolated sites. This study is part of the European Ely4off project (n° 700359). Under certain techno-economic hypothesis, four different system configurations supplied exclusively by photovoltaic are compared to find the optimal Levelized Cost of Electricity (LCoE): photovoltaic-batteries, photovoltaic-hydrogen-batteries, photovoltaic-diesel generator, and diesel generator; the influence of the location and the impact of different consumptions profiles is explored. Several simulations developed through specific modeling software are carried out and discussed. The main finding is that diesel-based systems still allow lower costs than any other solution, although hydrogen-based solutions can compete with other technologies under certain conditions.

Abstract:

Purpose The Kingdom of Saudi Arabia (KSA) is facing a rapid growth in energy demand mainly because of factors like burgeoning population, economic growth, modernization and infrastructure development. It is estimated that between 2000 and 2017 the power consumption has increased from 120 to 315 TWh. The building sector has an important role in this respect as it accounts for around 80 percent of the total electricity consumption. The situation is imposing significant energy, environmental and economic challenges for the country. To tackle these problems and curtail its dependence on oil-based energy infrastructure, KSA is aiming to develop 9.5 GW of renewable energy projects by 2030. The campus of the King Fahd University of Petroleum and Minerals (KFUPM) has been considered as a case study. In the wake of recently announced net-metering policy, the purpose of this paper is to investigate the prospects of rooftop application of PV in buildings. ArcGIS and PVsyst software have been used to determine the rooftop area and undertake PV system modeling respectively. Performance of PV system has been investigated for both horizontal and tilted installations. The study also investigates the economic feasibility of the PV application with the help of various economic parameters such as benefit cost ratio, simple payback period (SPP) and equity payback periods. An environmental analysis has also been carried out with the help of RETScreen software to determine the savings in greenhouse gas emissions as a result of PV system. Design/methodology/approach This study examines the buildings of the university campus for utilizable rooftop areas for PV application. Various types of structural, architectural and utilities-related features affecting the use of building roofs for PV have been investigated to determine the corrected area. To optimize the performance of the PV system as well as space utilization, modeling has been carried out for both horizontal and tilted applications of panels. Detailed economic and environmental assessments of the rooftop PV systems have also been investigated in detail. Modern software tools such as PVsyst, ArcGIS and RETScreen have also been used for system design calculations. Findings Saudi Arabia is embarking on a massive solar energy program as it plans to have over 200 GW of installed capacity by 2030. With solar energy being the most abundant of the available renewable resource for the country, PV is going to be one of the main technologies in achieving the set targets. The country has, however, unlike global trends, traditionally overlooked the small-scale and building-related application of solar PV, focusing mainly on larger projects. This study explores the prospects of utilization of solar PV on building roofs. Building rooftops are constrained in terms of PV application owing to wide ranging obstacles that can be classified into five types – structural, services, accessibility, maintenance and others. The total building rooftop area in the study zone, calculated through ArcGIS has been found to be 857,408 m2 of which 352,244 m2 is being used as car parking and hence is not available for PV application. The available roof area, 505,165 m2 is further hampered by construction and utilities related features including staircases, HVAC systems, skylights, water tanks and satellite dish antennas. Taking into account the relevant obstructive features, the net rooftop area covered by PV panels has been found to be in the range 25–41 percent depending upon the building typology, with residential buildings offering the least. To optimize both the system efficiency and space utilization, PV modeling has been carried out with the help of PVsyst software for both the tilted and horizontal installations. In terms of output, PV panels with tilt angle of 24° have been found to be 9 percent more efficient compared to the horizontally installed ones. Modeling results provide a net annual output 37,750 and 46,050 MWh from 21.44 and 28.51 MW of tilted and horizontal application of PV panels, sufficient to respectively meet 16 and 20 percent of the total campus electricity requirements. Findings of the economic analysis reveal the average SPP for horizontal and tilted applications of the PV to be 9.2 and 8.4 years, respectively. The benefit cost ratio for different types of buildings for horizontal and tilted application has been found to be ranging between 0.89 and 2.08 and 0.83 and 2.15, respectively. As electricity tariff in Saudi Arabia has been increased this year by as much as 45 percent and there are plans to remove $54bn of subsidy by 2020, the cost effectiveness of PV systems will be greatly helped. Application of PV in buildings can significantly improve their environmental performance as the findings of this study reveal that the annual greenhouse gas emission in the KFUPM campus can be reduced by as much as 40,199 tons carbon dioxide equivalent. Originality/value The PV application on building roof especially from economic perspective is an area which has not been addressed thus far. Khan et al. (2017) studied the power generation potential for PV application on residential buildings in KSA. Asif (2016) also investigated power output potential of PV system in different types of buildings. Dehwas et al. (2018) adopted a detailed approach to determine utilizability of PV on residential building roofs. None of these studies have covered the economics of PV systems. This study attempts to address the gap and contribute to the scholarship on the subject. It targets to determine the power output from different types of building in an urban environment by taking into account building roof conditions. It also provides detailed economic assessment of PV systems. Subsequent environmental savings are also calculated.

Abstract:

Renewable energy plays a very important role in the improvement and promotion of environmental sustainability in agricultural-related activities. This paper evaluates the techno-economic and environmental benefits of deploying photovoltaic (PV)- battery systems in a livestock farmhouse. For the energy requirements of the farm to be determined, a walkthrough energy audit is conducted on the farmhouse. The farm selected for this study is located in southern Nigeria. The National Renewable Energy Laboratory’s Hybrid Optimization Modeling for Electric Renewable (HOMER) software was adapted for the purpose of the techno-economic analysis. It is found that a standalone PV/battery-powered system in farmhouse applications has higher economic viability when compared to its diesel-powered counterparts in terms of total net present cost (TNPC). A saving of 48% is achievable over the TNPC and Cost of Energy with zero emissions. The results obtained show the numerous benefits of replacing diesel generators with renewable energy sources such as PV-battery systems in farming applications.

Abstract:

The analysis of the dynamics of the function intellectualization control agents’ development, which depends on the stages of formation and changes of technological structures in modern society, is presented. Sequential intellectualization of production factors associated with the development of skills management entities in the field of solving complex problems of choice, convergence of sciences in the techno-humanitarian space, as well as projective thinking – displaying mental variables on a variety of technical properties and characteristics of material objects in socio-economic systems. The article also shows that the main personal factors, the development of which should direct the attention of society, are the ability of a person, his education and mind (thinking). It is prove that their development requires special decision support tools that will ensure transparency, documentability and providing responsibility for possible consequences and attempts to manipulate the results of the choice. It also requires the desire and readiness of the management subject to internal and external interdisciplinary interaction between various scientific fields. The principles of projective control technology with feedback are being develop as a correction of the technical parameters of objects in accordance with the results of projective thinking. A number of classifiers for a variety of humanitarian ideas are introduce, represented by anthropic principles, contradictory attitudes, and various heuristics that can be strictly described by means of predicate calculus. They include the formation of algebraic systems based on modified subject-oriented operations of superposition and composition, as well as displays of ordinal scales on the relationship of scale to correct the parameters of artificial intelligence, modeling choice problem solution set of alternatives to the production process. The model example is given.

Abstract:

The model of long-term technical and economic development of industrial and post-industrial economic systems is constructed. The system consists of several subsystems existing simultaneously. Each new subsystem, embodying a new technical and economic mode, provides a higher level of per capita income. The transition to each new stage of technical and economic development — the transition to the predominance, the dominance of the technical and economic paradigm, and the beginning of the spread of a new technical and economic paradigm occurs at the moment when the upward half-wave of the Kondratiev cycle begins to form. To establish the moments of the onset of the upward halfwaves of Kondratiev cycles and the timing of the start of the spread of new techno-economic modes, econometric models of real per capita GDP in developed countries, including a smooth and cyclic (harmonic) component, were constructed. The average duration of the third cycle in these countries was 51.9 years, the fourth cycle — 49.8 years. Because of the construction of econometric models, it was possible to evaluate the productivity of relic, fourth, fifth and sixth technical and economic paradigms in developed countries. The average value of the maximum productivity of the fourth techno-economic mode was 2594 Geri-Hemis $ 1990, the fifth — 12,245 Geri-Hemis $ 1990, the sixth — 25 374 Geri-Hemis $ 1990. The average contribution to the real per capita GDP of relict modes and the fourth mode in the period of its domination was 5004 Geri-Hemis $ 1990, which corresponds to the value of 161,379 rubles. 2008. The excess of this value in Russia provided isdue to the spread of the fifth technical and economic mode. Its significant contribution to the real per capita GDP of the country began to observe since 2001 and by 2015 reached 47%. Modeling the period of the contribution of the fifth paradigm to Russia’s per capita GDP made it possible to predict the transition to its dominance in 2040. The forecast of the transition to the domination of the fifth mode in the regions of Russia is to include this time from 2010 to 2200. Construction of production functions based on data on per capita GRP over the years made it possible to establish that investment in fixed assets and an increase in the share of employed persons with a higher education can accelerate the spread of the fifth techno-economic mode and have received estimates of their effectiveness in the regions of Russia. A feature of the regions in which new modes did not receive proliferation was the low capitalization of new fixed assets and the increased number of employees of territorial bodies of federal executive bodies.

Abstract:

The limited capacity of renewable energy sources in the grid utility is a challenge. Increasing the capacity of renewable energy sources is supported by energy storage in the grid. The Battery Energy Storage System (BESS) allows storing more electricity from New and Renewable Energy (EBT) sources to meet load requirements. This paper designs a techno-economic study of various battery technologies using HOMER (Hybrid Optimization Modeling Software) software simulation. Simulations are made for grid-connected photovoltaic systems in Indonesia. HOMER is used to find the energy cost ($ / kWh) for each type of battery technology and battery system size. The simulation is designed using 1MWp PV component parameters, inverter, energy storage to be compared, residental load, and connected to the grid. The results will help to determine which technology and battery size is more suitable for the system. The findings from this paper resulted in the lowest Levelized Cost Of Energy (LCOE) of $ 1.03 in solar power generation.

Abstract:

The Integrated Rural Energy Planning (IREP) framework offers a unified road map for locating, planning and operating decentralized renewable hybrid off-grid energy systems for localized (rural) applications in low-income countries. This paper presents the culmination of the IREP framework and aims to illustrate the final step of the IREP framework for two communities in Nigeria. It is focused on two aspects. Firstly, the techno-economic modeling (investment and operation optimization) of a hybrid mini-grid system using HOMER Pro, a techno-economic evaluation tool; and evaluating the benefits of demand side management (DSM) based on energy efficiency on the overall system economics using a scenario-based approach. Secondly, the conceptualization of a sustainable business model using the business model canvas scheme to deliver measurable socio-economic impacts in these communities. The results provide valuable insights into rural electrification via renewable hybrid mini-grids powered primarily with solar photovoltaic technology. Transcending mere electricity access, electricity is provided for productive uses (considering disaggregated end-uses) by harnessing other dispatchable renewable energy resources such as waste biomass. Given high share of rural population in developing countries, these insights are applicable in these regions and further the realization of the United Nations’ goal of sustainable energy (SDG7) and sustainable cities and communities (SDG11).

Abstract:

Currently, the techno-economic performance of Wave Energy Converters (WECs) is not competitive with other renewable technologies. Size optimization could make a difference. However, the impact of sizing on the techno-economic performance of WECs still remains unclear, especially when sizing of the buoy and Power Take-Off (PTO) are considered collectively. In this paper, an optimization method for the buoy and PTO sizing is proposed for a generic heaving point absorber to reduce the Levelized Cost Of Energy (LCOE). Frequency domain modeling is used to calculate the power absorption of WECs with different buoy and PTO sizes. Force constraints are used to represent the effects of PTO sizing on the absorbed power, in which the passive and reactive control strategy are considered, respectively. A preliminary economic model is established to calculate the cost of WECs. The proposed method is implemented for three realistic sea sites, and the dependence of the optimal size of WECs on wave resources and control strategies is analyzed. The results show that PTO sizing has a limited effect on the buoy size determination, while it can reduce the LCOE by 24% to 31%. Besides, the higher mean wave power density of wave resources does not necessarily correspond to the larger optimal buoy or PTO sizes, but it contributes to the lower LCOE. In addition, the optimal PTO force limit converges at around 0.4 to 0.5 times the maximum required PTO force for the corresponding sea sites. Compared with other methods, this proposed method shows a better potential in sizing and reducing LCOE.

Abstract:

In this study, different carob extract-based media containing Medium A (included all ingredients), Medium B (included yeast extract and salts), Medium C (included (NH4)2SO4 and salts), Medium D (included only salts) and Medium E (included no ingredients) were evaluated for ethanol fermentation by Saccharomyces cerevisiae in a biofilm reactor and their results were used for kinetic modeling. The logistic model for cell growth, Luedeking-Piret model for ethanol production and Modified Luedeking-Piret model for substrate consumption were studied. Kinetic parameters were determined by fitting the observed values of the models. The findings indicated that the predicted data with the suggested kinetic model for each medium fitted very well the experimental data. Estimated kinetics were also in good agreement with experimental kinetics. The techno-economic analysis was performed with the unit costs of the components used in the medium and ethanol. Medium-based process economic feasibility proved carob extract-based Medium E and subsequently Medium D as most economical for ethanol production. The present study verified the potential of carob extract-based medium for increased economical production of ethanol. In conclusion, the ethanol production in a biofilm reactor is growth-associated since α (gP/gX) was greater than β (gP/gX.h) and Media D and E increased the economic production of carob extract-based ethanol.
