Allam Cycle

NET Power will combine with Rice Acquisition Corp. II (RAC II), a decarbonization solutions special purpose acquisition company (SPAC), in a new business direction designed to accelerate the deployment of NET Power’s much-watched novel natural gas–fired power plant technology. When the business combination transaction closes as expected in the second quarter of 2023, the new company, […]

NET Power, developer of the novel Allam-Fetvedt supercritical carbon dioxide (sCO2) power cycle, will build its first 300-MW natural gas–fired power plant at an Occidental-hosted site near Odessa, Texas. The “serial number one” project will demonstrate—at utility scale—NET Power’s potentially revolutionary technology, which promises to provide low-cost gas-fired power generation, no atmospheric emissions, no water […]

NET Power, developer of the novel Allam-Fetvedt supercritical carbon dioxide (sCO2) power cycle, says its 50-MWth test facility in La Porte, Texas, delivered power to the grid overnight on Nov. 16. The achievement marks a major milestone for the potentially revolutionary technology for which several commercial power plants are already under development. NET Power, a business venture […]

The inventor of the Allam-Fetvedt Cycle, a novel power cycle that uses supercritical carbon dioxide (sCO2), is collaborating with a subsidiary of Singapore-based Sembcorp Industries to potentially develop the UK’s first 300-MW natural gas–fired NET Power station at an existing site at Teesside, northeastern England.  Zero Degrees Whitetail Development Ltd. (ZDW), a subsidiary of North Carolina-based […]

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 southwest Colorado by 2025. The company on April 15 also said it will team with agricultural and processing firm Archer-Daniels-Midlands Co. (ADM) to locate a […]

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 a

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 “one size fits

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 developer is confident that the technology will be commercially deployed in 2022. Mike McGroddy, principal at 8 Rivers Capital, the venture capitalist firm that is […]

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 temperature and pressure above its critical point where liquid and gas phases are not distinguishable.  CO2 has a relatively low critical pressure of 7.4 megapascal […]

First-fire has been achieved at NET Power’s supercritical carbon dioxide (sCO₂) power plant—a test facility in La Porte, Texas, to demonstrate the potentially revolutionary natural gas–fueled Allam Cycle. The project is designed to produce low-cost electricity from natural gas while generating near-zero atmospheric emissions, including full CO₂ capture. NET Power, which is based in Durham, […]
