A new type of gas-fired power plant could help commercialise carbon capture and storage technology by providing cheap and pure carbon dioxide for sequestration.

Net Power, a United States-based company owned by Exelon Generation, McDermott and 8 Rivers Capital, started up a 25 MW gas-fired power plant in La Porte, Texas in May that uses an experimental combustion process called the Allam cycle.
