Abstract
- Abstract: Carbon Dioxide Capture and Storage (CCS) is a technology for reducing the amount of CO<subscript>2</subscript> to be emitted into the air, by storing the CO<subscript>2</subscript>. However, a CCS project itself emits some CO<subscript>2</subscript>. Therefore, to estimate CCS’s net CO<subscript>2</subscript> reduction effect, it is effective to apply life cycle assessment (LCA) to CCS projects. In this paper, we assumed a number of CCS project models to be feasible in Japan, and estimated the amount of CO<subscript>2</subscript> emissions to store one ton of CO<subscript>2</subscript> by applying LCA to the CCS projects. As a result, depending on the model case, 50% or more of the CO<subscript>2</subscript> amount to be stored was emitted. The study also revealed that approximately 80% of the CO<subscript>2</subscript> emissions at CCS-applied facilities derived from the energy consumed to re-heat the liquid absorbent that absorbed CO<subscript>2</subscript>. The study also indicated that a substantial amount of CO<subscript>2</subscript> emissions can be reduced if heat integration is conducted between the production equipment and the CCS equipment for energy utilization, such as bleeding CO<subscript>2</subscript> from a power station and other production equipment.
