Bioenergy with carbon capture and storage (BECCS) is a type of biomass carbon removal and storage that uses photosynthesis to remove CO₂ from the atmosphere, transforms the resulting biomass to produce an energy co-product (e.g. electricity or hydrogen), and captures the emitted CO₂ for long-term storage. This pathway is VCL 3-5, meaning that current quantification capacity can establish permanent carbon removal, but that for certain approaches, significant uncertainties remain.
