coal gasification Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen.

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.
Project
The US$1 billion project is planned to have three stages of development. 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, 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, was scheduled for 2015–2020.
In 2007, the project was joined by
Peabody Energy, the world's largest private sector coal company.
