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, […]

Researchers at Sandia National Laboratories in New Mexico announced they completed a successful test of a new power-generating technology, delivering electricity to the local grid using an energy conversion system that they say could drive a major increase in efficiency for power plants across the U.S. and perhaps the world. The researchers, in a news […]

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 […]

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 […]

The coal power industry acknowledges that to play a stable role in future power markets, it needs to modernize, and perhaps even overhaul its long-held status as a “conventional generator.” Could new

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 […]

Certain types of coal-fired power plants are capable of meeting the 636 kg CO2/MWh emissions limit in the Environmental Protection Agency’s (EPA’s) new source performance standards for new plants without relying on carbon capture and storage (CCS), but doing so will require leveraging cutting-edge technologies to improve efficiency, according to a new study from the Electric […]
