BioEnergy with Carbon Capture and Storage (BECCS) is a process whereby carbon dioxide - usually emitted from burning fossil fuels - is captured and then stored safely or possibly recycled. This means that the CO2 is not released into the atmosphere.
The National Grid acknowledges in its FES documentation that achievement of net zero by 2050 will require BECCS at a significantly greater scale than assumed in any of its core scenarios.
However, as of May 2019 and according to the Committee on Climate Change (CCC), BECCS is yet to get started in the UK. Indeed, the CCC have stated that deployment of CCS needs to start immediately with substantial deployment throughout the UK by the 2030s.
There is, however, a UK Government CCUS Deployment Pathway Action Plan that sets out a strategy and plan for CCS development and deployment.
One pilot programme in the UK is the BECCS programme at the Drax power station in Yorkshire.
