How the DOE Is Looking to Save Hydropower

The Department of Energy (DOE) unveiled a slate of measures to help U.S. hydropower thrive as costs for wind and solar plummet. Measures will include a roadmap to identify hydro’s value in a future grid, and a first-of-its-kind prize designed to encourage innovative and faster pumped storage construction techniques. In her opening speech at Waterpower […]

Deionization Resin Capacity Monitoring – White Paper

Eliminating contamination of a power plant’s water cycle is a critical element of protecting expensive plant equipment such as turbines and boilers from corrosion and pitting. Learn about a proactive approach for predicting when resin exhaustion will occur that offers significant benefits over the traditional elapsed time and totalized flow methods.

N.C. Officials Order Duke Energy to Excavate Coal Ash Ponds

North Carolina officials have ordered Duke Energy to excavate all its coal ash storage ponds in the state, saying the utility’s current plan for its coal ash sites does not sufficiently protect groundwater. The directive issued April 1 comes after regulators in other states, including Virginia, issued similar rulings regarding coal ash disposal in those […]

New Gas-Fired Plants Come Online in Michigan

Upper Michigan Energy Resources Corp. (UMERC) placed two new natural gas-fired generating stations into commercial operation on March 31, part of the company’s plan to reshape its generation fleet as it seeks to “balance reliability and customer cost with environmental stewardship.” UMERC, a subsidiary of WEC Energy Group, also retired the coal-fired 430-MW Presque Isle […]

Inside NET Power: Gas Power Goes Supercritical 

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 […]

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 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 […]
