The GreenGen power station (华能天津IGCC示范电站一期) is a 250-megawatt (MW) integrated gasification combined cycle (IGCC) power plant and proposed 800 MW carbon capture and storage (CCS) plant in Tianjin, China.

GreenGen Ltd. Co. China was established by the China Huaneng and Tianjin Jinneng Investment Company. Peabody Energy joined the consortium in December 2007 as the only non-Chinese participant in the program. The goal of the GreenGen program in Tianjin is to develop a large-scale IGCC–CCS demonstration project in China, at an estimated cost of US$1.5 billion. The program is being carried out in three phases.
The first phase is a 250-megawatt integrated gasification combined cycle power plant, which will convert coal into ‘syngas’ — a mixture of carbon monoxide and hydrogen — to be burned in specialized turbines to produce electricity. Construction of the plant began in 2009 and was completed in 2012.
The second phase is a pilot plant designed to send a "clean" stream of hydrogen through fuel cells and turbines to produce electricity, with carbon dioxide being captured for industrial use. Construction of Phase II began in early 2014.
The third phase will be an 800-megawatt power plant with full-scale carbon capture and storage in underground rock layers. The original planned completion date was 2015 but was then pushed back to 2020. The CO2 may be used for enhanced oil recovery at the Tianjing Dagang oil field.
As of November 2019 there have been no further developments on GreenGen, and the project appears to be shelved.
