Achieving negative emissions through combustion-based bioenergy with carbon capture and storage in China: A plant level techno-economic analysis

To achieve its ”30–60″ dual climate targets, China has to implement BECCS technology that will account for at least a quarter of all CO2 reductions. The techno-economic trade-offs associated with integrating CCS technology to biomass power plants within the Chinese context have not been fully explored in spite of China's huge combustion-based bioenergy industry. This study's findings demonstrate that CCS integration to a typical biomass CHP plant would result in a 90 % increase in the levelized cost of electricity, and sustainable use of China's biomass resources in the system would result in a CO2 abatement four times the current reduction from installed PV and wind technology. The negative emissions from the BECCS plant amount to 323 kt/yr at a competitive negative emission cost of 42.4$/ton-CO2. BECCS implementation in China requires a minimum negative emissions credit of 41$/ton-CO2 to achieve economic parity with fossil-fueled power, which is four times China's carbon price.
