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…


A Break in the Nuclear Waste Impasse?

Spent nuclear fuel has continued to accumulate at sites across the nation, paralyzed by a government deadlock on a nuclear waste management strategy formally established 35 years ago. Can recent…


Intrusion-Tolerant SCADA Demonstrated at Power Plant

Researchers have successfully demonstrated an open-source supervisory control and data acquisition (SCADA) system designed to withstand attacks and compromises on the power grid. The intrusion-tolerant system—called “Spire”—keeps power flowing even…


Decade-Old Power Grid Problem Solved by Smart Grid Technology 

A control system that smooths out inter-area oscillations—a problem affecting power systems connected by relatively weak tie lines—has been successfully demonstrated by researchers from Sandia National Laboratories and Montana Tech…
