supercritical CO2

Construction of the 10-MWe Supercritical Transformational Electric Power (STEP) pilot plant, a public-private collaboration to demonstrate and test supercritical carbon dioxide (sCO2) power generating technology, is making marked progress toward a mid-2022 startup date.  Attendees from Experience POWER, HydrogeNext, and the Distributed Energy Conference, three of POWER’s annual in-person events, which took place last week in […]

Gas turbines have grown into a hallmark of the modern power system for their high efficiency, reliability, operational flexibility, fuel flexibility, and low-emission power options. But if gas turbines are to

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

One of the National Energy Technology Laboratory’s (NETL’s) key initiatives aims to bridge the gap in research infrastructure and accelerate advanced alloy development and manufacturing. Materials are

A project to demonstrate a novel power cycle that promises to produce low-cost, reliable, and flexible power from natural gas—while generating no atmospheric emissions, and fully capturing carbon dioxide—is inching closer to commissioning. Its developers are now actively assessing siting for the first commercial-scale 300-MW NET Power facility. NET Power’s 50 MWth Demonstration Plant in La […]

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 […]

To be a relevant player in the future power mix, coal power efficiency and costs must improve, and technologies in the realm of research and development promise to do just that. Although most experts agree

The Department of Energy’s National Energy Technology Laboratory (NETL) will award up to $80 million to a 10-MWe pilot project that seeks to advance the development and commercialization of supercritical carbon dioxide (sCO2) Brayton power cycles. The plant will be managed by three research entities: the Gas Technology Institute (GTI), Southwest Research Institute (SwRI), and […]
