About this Research Topic
Numerous technologies including biological and thermochemical processes can transform biomass to bioenergy in the form of biogas, biohydrogen, bioethanol and other liquid biofuels.
Despite the significant role of bioenergy in a future energy system, the deployment of bioenergy may encounter problems from the perspectives of production efficiency, sustainability and economic viability. This Research Topic aims to delve into the latest advances for biofuels production through bio- and thermo-chemical approaches with particular interest on innovative and novel deployment methods that are being investigated in both the fundamental and applicable fields. The ultimate objective is to gain insight into such biofuel production technologies and promote economically feasible biofuels which are of sufficient sustainability to mitigate greenhouse gas emissions.
The Topic Editors encourage submissions of original research articles, short communications, industrial and country/region case studies, and review articles. This Research Topic covers but is not limited to the following concepts:
• Novel pre-treatment methods (e.g. hydrothermal, ionic liquid, deep eutectic solvent, etc.) for biomass for the biological production of biofuels
• Biological technologies (e.g. dark/photo fermentation, anaerobic digestion) for biofuel production
• Biological methanation for biogas upgrading in in-situ and ex-situ systems
• Thermochemical technologies (e.g. hydrothermal carbonization, pyrolysis and gasification) for biofuel and materials production (e.g. biochar)
• Cascading bioenergy systems and circular economy pathways for sustainable biofuel production by integrating biological and thermochemical technologies
• Novel utilization of valuable resources (e.g. biochar) derived from biomass
• Techno-economic (e.g. cost-benefit analysis) and environmental sustainability (e.g. life-cycle assessment) of advanced biofuels
Keywords: Advanced biofuels, Circular economy, Biogas, Biochar, Techno-economic analysis
