Towards the Carbon Circulation Society: Direct Air Capture by Kawasaki CO2 Capture Technology and CO2 utilization

Abstract

Aiming realization of a carbon circulation society, we considered a social model in which the carbon dioxide (CO2) can be used effectively by recovering CO2 from the air and converting it to valuables. To realize Direct Air Capture (DAC), we developed amines for capturing low-concentration CO2, and developed a system applying the CO2 capture technology developed until now by Kawasaki Heavy Industries, Ltd. (Kawasaki CO2 Capture, KCC). Additionally, we performed a survey on the technology for the effective use of CO2 applied to DAC as well as constructing a carbon circulation society model, and we also created a lifecycle assessment model (LCA) to evaluate the effectiveness of this social model using a carbon life cycle assessment model. This project will be conducted with the consignment of the Ministry of the Environment, Government of Japan for three years from 2019, and here we will report on the achievements of the first year.
