- Capture capacity of over 500 tons of CO2 a day

 OMUTA, Fukuoka, Japan—Toshiba Energy Systems & Solutions Corporation (Toshiba ESS) today announced that it has started construction of a large-scale carbon capture facility at Mikawa Power Plant (capacity: 50,000 kW) operated by Toshiba ESS’s subsidiary, SIGMA POWER Ariake Corporation, in Omuta, Fukuoka prefecture. The facility will start operation in 2020, and Toshiba ESS will use it to evaluate the technology’s performance, cost and environmental effects.

 The new facility will be Japan’s first*1 carbon capture unit which will capture over 50% of CO2 emission from thermal power plant. This facility will capture more than 500 tons of CO2 a day, over 50% of Mikawa’s daily emissions. As Mikawa operates biomass-fired power generation, it will also be the world’s first*2 power plant with a large-scale carbon capture demonstration facility capable of capturing carbon dioxide from biomass power generation.

 Toshiba ESS already operates a pilot carbon capture facility at Mikawa that can capture 10 tons of CO2 a day. This has been used to verify and demonstrate practical operation of the system, including its performance, operability and maintainability. Toshiba ESS also completed the world's first commercial-use carbon capture and utilization (CCU) system at a municipal waste incineration plant, in Saga, Japan, in 2016. Know-how gained from these projects will be utilized in the design of systems for capturing CO2 from various exhaust gas streams.

 Toshiba ESS is one of 13 entities*3 selected to carry out a major five-year project to promote clean energy generation, the “Demonstration of Sustainable CCS Technology Project”, sponsored by Japan’s Ministry of the Environment (MOE). Design, engineering and construction of the new facility will be done by Toshiba ESS as part of this project.

 Commenting on the large scale carbon capture facility, Takao Konishi, Director, Vice President of Thermal & Hydro Power systems & Services Div. of Toshiba ESS said, “Toshiba is committed to the realization of a low-carbon society. Through the Mikawa project we will further contribute early realization of CCS. We see this as an important step toward global promotion of cleaner energy production.”
