8 Rivers Unveils 560 MW of Allam Cycle Gas-Fired Projects for Colorado, Illinois

8 Rivers Capital, inventor of a novel supercritical carbon dioxide (CO2) cycle, plans to begin operating a 280-MW NET Power natural gas–fired plant within the Southern Ute Indian Reservation in…


First Commercial Deployment of Supercritical CO2 Power Cycle Taking Shape in Alberta

Siemens Energy and Canadian pipeline company TC Energy in February agreed to commission a novel waste-heat-to-power facility in Alberta by 2022 that captures waste heat from a gas-fired turbine operating…


Using Technology to Tackle Power Plant Emissions

Power plant owners and operators have a range of systems available to help reduce pollutants at their facilities, depending on a number of factors. And industry experts agree—there is no…


300-MW Natural Gas Allam Cycle Power Plant Targeted for 2022

Testing continues at NET Power for a much-watched project that is demonstrating production of low-carbon natural gas power. The project is using a supercritical carbon dioxide (sCO2) cycle, and its…


What Are Supercritical CO2 Power Cycles?

While conventional power plant cycles produce power from turbines using water or steam as the working fluid, supercritical carbon dioxide (sCO2) cycles use CO2 that is in a supercritical state—at a…
