“…Although the setup is simple and cheap, it may be less sustainable due to limited applications and interconnection with agricultural activities which supply the feed-stock. The solution to sustainability at the household level is to diversify biogas applications and sources of feedstock for the biodigester [18,19,22,80]. A diversified and more sustainable biogas system is demonstrated in Figure 2.…”

“…This has effectively converted electricity consumers, both large and small scale to prosumers. Prosumers are customers who are both producers and consumers of electricity [34,80]. Figure 3 demonstrates a grid electricity-connected biogas production and electricity generation system made possible by the advances in decentralized generation and smart grid technology.…”

“…According to [101,114], low feed-in tariffs and low capacity of grids to absorb small distributed electricity sources are another limitations to the wider use of biogas to electricity systems. Other limitations are lack of on-grid generation opportunities, high upfront costs in terms of feasibility studies, financial barriers, design capacity, construction, operation, and maintenance; legal and policy barriers and relatively high costs of production and maintenance in comparison with fossil fuels energy systems and changing and short-lasting regulatory frameworks that do not support biogas programs all combined make the development of grid-connected biogas systems difficult to implement [36,80,118].…”

“…Compared to fossil fuels, anaerobic digestion technology reduces greenhouse gas emissions by consuming locally available biowaste. Additionally, the byproduct of biogas production also called digestate can be used as a high value for sustainable agricultures [7,58,117,122] [13,38,80,89] It is necessary to put in place facilitating legal and policy framework if biogas electricity generation must develop because of various technical and economic challenges in a competitive market. In Germany, biogas power generation is profitable just because of grid connection and attractive feed-in tariffs.…”

“…In Germany, biogas power generation is profitable just because of grid connection and attractive feed-in tariffs. It is noted that output-oriented support schemes as opposed to investment-oriented financial support are more effective and successful in promoting biogas power generation [3,80,82,122].…”

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.
