Biochar and bioenergy crop cultivation with carbon capture and storage (BECCS) are two major negative emission technologies for carbon dioxide removal (CDR). However, biochar production is limited by biomass supply, while BECCS depends on costly CCS infrastructure and faces storage constraints. Here, a novel combination of biochar with biomass supply from dedicated bioenergy crops (BCBE) is proposed to overcome their respective limitations. Through retrofitting current biomass power plants in China with pyrolysis systems or CCS, biomass power plants are assumed to use either residues from agriculture and forestry or from dedicated bioenergy crops on abandoned croplands to meet their capacity for biochar production.
