Summary
Biomass energy conversion continues to play a vital role in the global transition toward sustainable and carbon-neutral energy systems. As concerns over fossil fuel depletion and greenhouse gas emissions intensify, innovative approaches to convert biomass and wastes into clean fuels, chemicals, and energy carriers have become increasingly important. Advances in thermochemical, biochemical, and hybrid conversion technologies are essential to improve process efficiency, resource utilization, and environmental performance.
This special issue aims to present recent progress, emerging trends, and interdisciplinary developments in biomass energy conversion. Contributions are invited that explore fundamental studies, novel processes, integrated systems, and modeling or optimization approaches that advance the understanding and application of biomass conversion. Both experimental and theoretical works are welcome.
Potential themes and topics include (but are not limited to):
· Thermochemical and biochemical conversion pathways (pyrolysis, gasification, hydrothermal, fermentation)
· Catalytic and co-processing technologies for biofuels and biochemicals
· Biomass pretreatment, upgrading, and feedstock characterization
· Process modeling, kinetic studies, and reactor design
· Life cycle assessment, techno-economic, and sustainability analyses
· Biomass-derived carbon materials and functional products
· Machine learning and data-driven modeling in biomass conversion
