Bioenergy with carbon capture and storage

Bioenergy with carbon capture and storage (BECCS) is the process of extracting <a href="/facts/Bioenergy/BvDWWFGP">bioenergy</a> from <a href="/facts/Biomass_(energy)/bN7lfSb2">biomass</a> and capturing and storing the carbon dioxide (CO2) that is produced.
Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO2 from the air through <a href="/facts/Photosynthesis/TMV7w693">photosynthesis</a>. After the biomass is harvested, energy ("bioenergy") is extracted in useful forms (electricity, heat, <a href="/facts/Biofuel/RWu7b6Y3">biofuels</a>, etc.) as the biomass is utilized through combustion, fermentation, pyrolysis or other conversion methods. Using bioenergy releases CO2. In BECCS, some of the CO2 is captured before it enters the atmosphere, and stored underground using <a href="/facts/Carbon_capture_and_storage/d8DzjobH">carbon capture and storage</a> technology. Under some conditions, BECCS can <a href="/facts/Carbon_dioxide_removal/dY6ADxrJ">remove carbon dioxide</a> from the atmosphere.
The potential range of negative emissions from BECCS was estimated to be zero to 22 <a href="/facts/Giga/gowFuavY">giga</a><a href="/facts/Tonnes/gMymLmWv">tonnes</a> per year. As of 2024, there are large-scale 3 BECCS projects operating in the world. Wide deployment of BECCS is constrained by cost and availability of biomass.: 10  Since biomass production is land-intensive, deployment of BECCS can pose major risks to food production, human rights, and biodiversity.
