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.
