As measures against global warming, demand has been growing for carbon dioxide capture and storage (CCS) technologies that can separate and capture carbon dioxide (CO2) emitted in the flue gas of various sources and isolate and store the captured CO2 underground, as well as carbon dioxide capture and utilization (CCU) technologies for the effective utilization of captured CO2.
Toshiba Energy Systems & Solutions Corporation has been promoting the research and development of CO2 separation and capture technologies using chemical absorption. We have already applied these technologies to a pilot plant constructed at the Mikawa Power Plant of SIGMA POWER Ariake Corporation, and have been verifying the performance, usability, operability, and maintainability of this approach. Based on the knowledge accumulated through the operation of the pilot plant, we have newly constructed the world’s first large-scale CO2 capture facility for the treatment of flue gas emitted from the biomass power plant at the Mikawa Power Plant, and evaluated the demonstration facility through test operation. From the results obtained, we have confirmed that this system makes it possible to stably capture more than 600 tons of CO2 per day and to further suppress atmospheric emissions of amines used in CO2 absorption solvents, thereby improving environmental performance.
