Global potential for biomass and carbon dioxide capture, transport and storage up to 2050

► Biomass combined with carbon capture and storage option for negative greenhouse gas emissions. ► We assess the global potential for 'biomass-CCS' routes up to 2050. ► We analyse the technical and economic potential for six bio-CCS routes. ► We show an annual technical potential of up to 10 gigatonnes of negative greenhouse gas emissions. ► Sustainable biomass potential is limiting factor for bio-CCS in most regions.
