Most widely analysed are those that remove carbon dioxide from the atmosphere, either to geologic formations such as
bio-energy with carbon capture and storage [145][146][147] and carbon dioxide air capture, [147] or to the soil as in the case with biochar.
Another method is
bio-energy with carbon capture and storage.
Bio-energy with carbon capture and storage (BECCS) is a greenhouse gas mitigation technology which produces negative carbon dioxide emissions by combining biomass use with geologic carbon capture and storage.
Not exact matches
In its latest report, the IPCC said: «Net negative emissions can be achieved when more GHGs are sequestered than are released into the atmosphere (e.g., by using
bio-energy in combination
with carbon dioxide
capture and storage).
BECCS, which combines
bio-energy production (biomass fuel - power stations, pulp mills and bio-fuel plants)
with carbon capture and storage technology, has the potential to generate «negative emissions» that could help society avoid exceeding critical thresholds in this century and beyond.
