Mitsubishi Heavy Industries, Ltd. (MHI) started developing technology for CO2 capture from combustion flue gas with Kansai Electric Power Co., Inc. in 1990. The first commercial plant was delivered in 1999 for a Malaysian fertilizer company, and as of January 2018, a total of 13 commercial CO2 capture plants are currently in service around the world. MHI's CO2 capture plant is applied to various combustion flue gases including heavy oil, coal, and natural gas, and the recovered CO2 is used for a variety of applications including the enhancement of fertilizer/methanol production, general use such as for dry ice, and EOR (Enhanced Oil Recovery) for the purpose of increasing oil production. Most notably, MHI delivered the world's largest CO2 capture plant (4,776 metric tonnes per day) on a coal fired power plant to Petra Nova Parish Holdings LLC, U.S. at the end of December 2016. The project has been recognized by well-known publications including Power Engineering, Power Magazine, and Engineering News Record (ENR). MHI continues to promote research and development of CO2 capture technology to improve the reliability, reduce the cost of future CO2 capture plants, and increase the application of its technology.
