One, known as BECCS, involves incorporating CO2 capture into biomass-based electricity-generation, in which organic matter such as crops and wood pellets are burned to produce power. Other options include: huge facilities where the carbon is extracted from the air before being stored in the ground; the use of specially treated charcoal (biochar) that locks in carbon; and “enhanced rock weathering” – loosely based on the carbon removal that occurs with natural erosion.
