GE Marks ‘Ultra Low’ NOx Gas Turbine Technology Triumph

In a significant technical triumph, GE has completed first installation of a new gas-fired power plant technology that it says can reduce nitrogen oxide (NOx) emissions to 5 parts per million (ppm).  GE on April 11 completed combustion upgrades on nine GE 9E gas turbines at five power generation enterprises in Shenzen, a major industrial […]

Vogtle 2 Installs World’s First Full Accident-Tolerant Fuel Assemblies

The world’s first complete advanced nuclear fuel test assemblies containing accident-tolerant fuel (ATF) have been installed at Southern Co.’s Alvin W. Vogtle Electric Generating Plant’s Unit 2 in Georgia.  Nuclear giant Framatome delivered four GAIA lead fuel assemblies containing enhanced ATF (EATF), including both pellets and cladding, to the plant owned by Georgia Power in […]

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 […]

Controlling Boiler Level When Operating Conditions Change

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve heat rate

Flexible Operation of Nuclear Power Plants Ramps Up

A widespread misconception persists that nuclear plants can only function as inflexible baseload sources of power—and it’s hurting prospects for the nuclear sector’s role in the world’s future power

The Economic Thicket of Generating Cost Comparisons

Comparing the costs of differing electric generating technologies has become popular among advocates for particular technologies and those seeking to find the optimal approach to new generation. While getting

Bipartisan Senators Move to Cement Nuclear Power’s Future

A wide-ranging bill introduced by a large group of bipartisan U.S. senators on March 27 seeks to cement the role advanced nuclear reactors will play in the nation’s future power mix.  The “Nuclear Energy Leadership Act” (NELA), aims to “reestablish U.S. leadership in nuclear energy,” which has been lost to state-sponsored development in Russia and […]
