Japanese high-tech companies are the front runners in the technology to recover CO2 in the world. Mitsubishi Heavy developed a new plant that can recover 3,000 tons of CO2 per day, six times bigger capacity than the existing recovery plant. The company has been operating a plant with a daily recovery capacity of 500 tons in Mobile of the state of Alabama of the U.S. A recovery plant consists of CO2 recovery equipment and large-scale compressors, etc., and recovers only CO2 from gas emissions using a special absorbing solution. If a nuclear power plant with an output of 1 million kW is replaced by a coal-fired thermal power plant, 12,000 tons of CO2 will be emitted daily.
In addition to the recovery technology, Mitsubishi Heavy is developing a technology to pour CO2 into an aging oilfield to regenerate it. Aging oilfields mostly have crude oil of high viscosity, and increasing the fluidity of the residual oil with the help of poured CO2 can regenerate them. At the same time, should an oil layer exist below the bedrock, it is possible to increase the pressure by pouring CO2 for higher production efficiency. According to International Energy Agency, the world capacity of coal-fired thermal generation plants will increase two times over the level in 2008 to 1,400 million kW in 2030, and reduction of CO2 emissions by dint of recovery and storage will reach 8,000 million kW by 2050. Other Japanese leading high-tech companies like IHI, Hitachi, and Toshiba are actively developing the CO2 recovery business both at home and abroad.The CO2 recovery plant in Mobile in the state of Alabama by Mitsubishi Heavy
