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 . 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 .

NET Power, which is testing the technology at a gas-fired power plant in La Porte, Texas, says its technology eliminates the need to sequester the CO2 separately and is a cheaper and more efficient alternative to systems that have mostly not been commercially viable. The company says another advantage of its system is that it uses very little water because CO2, rather than steam, is used to power the turbines.
