O-14　Surveys on BioEnergy CCS(BECCS)

Abstract

In this paper, BioEnery CCS(BECCS) that would be needed in the case with drastic CO₂ emissions reduction is surveyed. BECCS is the combination of the commercial technology of bioenergy uses and semi-commercial technology of CCS, and its technical hurdle towards introduction is not strict among the options of CDR(Carbon Dioxide Removal). BECCS is introduced at a large scale in the long-term energy scenarios collected by IPCC under stringent CO₂ emissions reduction, such as 1.5°C target. The CO₂ reduction costs of BECCS are assumed to be 3 to 7 times as much as those of thermal power generation with CCS. However, the large-scale uses of BECCS impose a burden on future generation that must use CDR at a large scale.
