GreenGen under construction

China Huaneng Group (CHNG) is leading this project in China to design, develop and operate a 400MW coal-fired IGCC power plant near Tianjin, south east of Beijing.

GreenGen was launched in 2005 with the aim of demonstrating integrated coal gasification, and hydrogen production and power generation together with CCS. The ultimate aim is for high-efficiency power generation with near-zero emissions.

The project partners include the country’s five largest power companies, the two largest coal companies – including the China National Coal Group and the Shenhua Group – and one investment group. CHNG holds a 51% interest in the venture. The arrival of global coal company Peabody Energy in 2007 was seen as significant. The project has the full support of the state government.

The Good Spring IGCC project in the US, being led by EmberClear, is also planning to use the technologies being developed and demonstrated by GreenGen.


Construction of Phase I – to build and operate a 250MW IGCC power plant for R&D into key technologies – began in July 2009. It was   originally expected online at the end of 2011. According to media reports, the Phase 1 project was handed over for operation in December, 2012. The 400MW IGCC demonstration project (Phase 3) is on track for completion in 2015. Huaneng has already begun work on phase two — a smaller pilot plant that will produce electricity from hydrogen, with CO2 being captured for industrial use. CO2 injection is then expected to begin in 2018.


The total estimated cost of GreenGen is $1 billion. The first stage of GreenGen had an estimated investment of $360 million. CHNG is backing the venture with a 51% investment share, with the other partners each having a 7% share. The project is being supported by government agencies, including the National Development and Reform Commission, as well as international partners, such as development banks, NGOs and industry.
