29 Summary Toshiba Corporation holds a well respected history as leading and reliable thermal power plant technology supplier in the global market. Toshiba has positioned Carbon Capture as one of the key technologies to decarbonize thermal power plant. In view of actual application to power plants, Toshiba constructed its PCC Pilot Plant in Mikawa (Japan), which works to actual live flue gas of a coal fired thermal power plant. The plant has accumulated more than 4300 hours of operation to date. High performance of Toshiba solvent system was proven in 2010 tests, and was improved further by system modification made in Toshiba s search for improved performance solvents and system application continues through its comprehensive system verification and implementation program. 29 / 30
