GreenGen (Chinese: 绿色煤电; pinyin: lǜsèméidiàn; literally: "green colour coal electricity") is a project in Tianjin, China which aims to research and develop high-tech low-emissions coal-based power generation plants.


Funded by a group of power companies led by SOE China Huaneng Group and the Chinese government's 863 Program, the GreenGen project commenced in 2005. A key technology in the project is the integrated gasification combined cycle (IGCC), which is a coal gasification process that turns coal into a gas before burning it, hence allowing power generation to be more efficient and releasing less carbon and other pollutants.[1]


The US$1 billion project is planned to have three stages of development.[2] The first stage involves building a 250 megawatt IGCC plant in Tianjin. Construction began in 2009 and the plant was scheduled to begin operation by 2011,[3] but since then delayed to 2012 spring. The work has also begun on the second stage, involving a smaller pilot plant which uses both fuel cell and turbine to generate electricity while converting CO2 for industrial use at the same time. The third stage, 400 megawatt power plant with carbon capture and storage (CCS) technology, is now scheduled for 2015-20.[4]

In 2007, the project was joined by Peabody Energy, the world's largest private sector coal company.[5]
