GreenGen, majority held by China's largest power producer Huaneng Group, announced that they will build a near-zero emissions of carbon dioxide coal-fired power plant in Tianjin.

The green power plant will gasify coal to extract the hydrogen while sequestering the CO2 emissions, popularly known as CCS – carbon capture and storage. The carbon dioxide will then be pumped into oil wells to aid in petroleum recovery, explained by a senior manager.

The first phase of the clean power plant is expected on line in 2011, with a generation capacity of 250 MW, as well as realizing 2000 tonnes per day of coal gasification.

The project includes three phases for additional generation and capture, expanding to 650 MW by 2016 and realizing 3500 tonnes per day of gasification.
