Climate change is driven by the accumulation of greenhouse gases, so alongside rapid CO₂ emission reductions, carbon dioxide removal (CDR) is increasingly needed, and biomass offers a strategic pathway by converting photosynthetically fixed carbon into useful products and energy while enabling net CO₂ removal. Building on this biomass utilization perspective, this thesis bridges sustainable materials science and system-level CDR assessment by first producing and engineering advanced biomass-derived carbon materials (biochar) through one-step impregnation and pyrolysis, and then evaluating biochar as a standardized carbon product within a high-level, integrated biochar (BC) – BECCS (bioenergy with carbon capture and storage) framework (BC+CCS), leveraging the fact that both technologies rely on the same biomass feedstock supply chains.
