How CO2 can be removed from the air
Bioenergy with Carbon Capture Storage (BECCS) Bioenergy with Carbon Capture and Storage is about capturing CO 2 in bioenergy applications before it is released into the atmosphere. The CO 2 is then to be either stored by Carbon Capture and Storage (CCS) or reused by Carbon Capture Use and Storage (CCUS).
