“…Further studies based on scenarios for other developing countries in Africa showed that biogas grid-connected electricity generation is not economically viable for small biogas plants [43, 110] [43, 77]. Therefore, for many smallholders and mediumscale grid-connected biogas plants, governments should Journal of Energy provide incentives in form of attractive feed-in tariffs and other technical and financial incentives including technical support [26,32]. Therefore, based on available studies, biogas power plants are not commercially viable without subsidies or guaranteed high prices or fed in tariffs of about 0.20 US$/ kWh for the generated electricity from biogas power plants that is sold to the grid.…”

“…Trigeneration can be said to be an enhanced form of cogeneration systems where cooling is added to the basic cogeneration system. The main benefits of a cogeneration system are a reduction in fuel use and reduced cost of generation [151], while the use of biogas as heat sources is a way of mitigating greenhouse gas emissions and global warming [26,32,152]. The triple application of the same energy input for cooling, heating, and electricity generation is referred to as trigeneration.…”

“…Various organic feedstocks can be used to produce biogas through anaerobic digestion which can be processed through enrichment to produce natural gas like biomethane. Biomass waste conversion to biogas provides a sustainable pathway for a more circular economy with benefits like reduced carbon emissions, better and useful organic waste management, and greater resource use efficiency [26,32]. There are various options for conversion of biogas to electricity, but economic studies favor internal combustion engines and Stirling engines as the most economical, especially in small-scale power production.…”

Biogas is competitive, viable, and generally a sustainable energy resource due to abundant supply of cheap feedstocks and availability of a wide range of biogas applications in heating, power generation, fuel, and raw materials for further processing and production of sustainable chemicals including hydrogen, and carbon dioxide and biofuels. The capacity of biogas based power has been growing rapidly for the past decade with global biogas based electricity generation capacity increasing from 65 GW in 2010 to 120 GW in 2019 representing a 90% growth. This study presents the pathways for use of biogas in the energy transition by application in power generation and production of fuels. Diesel engines, petrol or gasoline engines, turbines, microturbines, and Stirling engines offer feasible options for biogas to electricity production as prme movers. Biogas fuel can be used in both spark ignition (petrol) and compression ignition engines (diesel) with varying degrees of modifications on conventional internal combustion engines. In internal combustion engines, the dual-fuel mode can be used with little or no modification compared to full engine conversion to gas engines which may require major modifications. Biogas can also be used in fuel cells for direct conversion to electricity and raw material for hydrogen and transport fuel production which is a significant pathway to sustainable energy development. Enriched biogas or biomethane can be containerized or injected to gas supply mains for use as renewable natural gas. Biogas can be used directly for cooking and lighting as well as for power generation and for production of Fischer-Tropsch (FT) fuels. Upgraded biogas/biomethane which can also be used to process methanol fuel. Compressed biogas (CBG) and liquid biogas (LBG) can be reversibly made from biomethane for various direct and indirect applications as fuels for transport and power generation. Biogas can be used in processes like combined heat and power generation from biogas (CHP), trigeneration, and compression to Bio-CNG and bio-LPG for cleaned biogas/biomethane. Fuels are manufactured from biogas by cleaning, and purification before reforming to syngas, and partial oxidation to produce methanol which can be used to make gasoline. Syngas is used in production of alcohols, jet fuels, diesel, and gasoline through the Fischer-Tropsch process.

“…Emerging tools such as ANN are vital in improving small-scale biogas digesters' operation and maintenance. In contrast, the benefits of large-scale biogas digesters, such as the high capacity to process and generate large volumes of biogas, benefit from economies of scale [ 151 ]. Small-scale or household digesters promote localized, flexible, cost-effective feedstock digestion for biogas generation.…”

“…Biogas contains carbon dioxide along with methane, which lowers the calorific value (22 megajoule/cubic meter); therefore, biogas needs to be cleaned and purified into pure biomethane (36 megajoule/cubic meter), which can be used as a vehicle fuel or injected into the gas grid (Akbulut et al 2021 ). Upgraded biomethane is more economical in transportation and compression and avoids the negative effects of impurities, such as hydrogen sulfide and water vapor, on downstream equipment compared to raw biogas and has broader uses (Sahota et al 2018 ).…”

Rice straw for energy and value-added products in China: a review

et al. 2023

View full text Add to dashboard Cite

The rise of global waste and the decline of fossil fuels are calling for recycling waste into energy and materials. For example, rice straw, a by-product of rice cultivation, can be converted into biogas and by-products with added value, e.g., biofertilizer, yet processing rice straw is limited by the low energy content, high ash and silica, low nitrogen, high moisture, and high-quality variability. Here, we review the recycling of rice straw with focus on the global and Chinese energy situations, conversion of rice straw into energy and gas, biogas digestate management, cogeneration, biogas upgrading, bioeconomy, and life cycle assessment. The quality of rice straw can be improved by pretreatments, such as baling, ensiling, and co-digestion of rice straw with other feedstocks. The biogas digestate can be used to fertilize soils. The average annual potential energy of collectable rice straw, with a lower heating value of 15.35 megajoule/kilogram, over the past ten years (2013–2022) could reach 2.41 × 109 megajoule.
