1st power plant that runs on CO2 instead of steam being made
US-based researchers are building the first-ever power plant that will use carbon dioxide (CO2) to turn turbines instead of using steam to generate electricity. CO2 would be heated and pressurised into a supercritical dense state, which allows using smaller turbines and increasing efficiency. A carbon emission-free test facility would start operating by end of this year in Texas, researchers said.
