US - based NET Power is testing a new technique for carbon capture and storage that uses pure oxygen to burn natural gas , allowing CO2 to be extracted directly during the process . NET Power , which is testing the technology at a gas - fired power plant in La Porte , Illinois , says its technology eliminates the need to sequester the CO2 separately and is a cheaper and more efficient alternative to technologies that have mostly not been commercially viable . Correction: The company says another advantage of its system is that it uses very little water because CO2 , rather than steam , is used to drive the turbines .
