The Electric Reliability Council of Texas (ERCOT) on Sept. 6 issued an Energy Emergency Alert 2 (EEA 2) after grid conditions quickly deteriorated around sunset (7:30 p.m.) as demand soared and operating power reserves plunged. The grid operator said that the emergency operations were necessary “due to a combination of dropping operating reserves and frequency.” […]

Marking a significant inroad to establish a South Korean foothold in the world’s gas turbine technology market, heavy industrial company Doosan Enerbility this summer began commercial operation of its first

A proposed rule unveiled by the Environmental Protection Agency (EPA) on April 5 could considerably tighten the Mercury and Air Toxics Standards (MATS) for power plants, with specific repercussions for coal- and oil-fired generation. The proposed rule seeks to significantly update the 2012–finalized National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired […]

The spectrum of geothermal technologies is quickly evolving. This supplement to POWER’s April 2023 feature, “Startups Are Shaking Up Geothermal Power’s Potential,” briefly explains the differences between some engineered geothermal systems. Conventional geothermal energy is largely produced by hydrothermal systems, which consist of hot water circulated in deep-seated permeable rocks. Resource temperature ranges from high (greater […]

Ansaldo Energia and partners have kicked off the FLEX4H2, a four-year project to design, develop, and validate a highly fuel-flexible gas turbine combustion system based on Ansaldo’s sequential combustion technology that will be capable of operating with up to 100% hydrogen. The FLEX4H2 (or Flexibility for Hydrogen) officially began on Jan. 1 and will run […]

Marking a major milestone, Centrus Energy—a firm under contract with the U.S. Department of Energy (DOE) to demonstrate production of high-assay low-enriched uranium (HALEU) with domestic technology—on Feb. 9 said it completed construction and initial testing of its advanced uranium enrichment centrifuge cascade as well as most of its associated support systems. Once the company […]

Spun out of Exelon Corp. a year ago, Constellation Energy’s competitive generation and customer-facing energy businesses represent a new power company paradigm that conforms to decarbonization. But the company that today holds the largest nuclear fleet in the U.S. will still face a unique array of challenges.

The Fukushima Hydrogen Energy Research Field is revitalizing an earthquake-stricken region and providing a remarkable boost to Japan’s ambitions to launch a hydrogen society. While global interest in

For most of my childhood growing up in a small town in the foothills of North Carolina, my dad worked in the blanket factory as a supervisor in the labs—working on fabric treatments, dyes, weaves, and all the other things that you’d never think about going into the design of a blanket. On Saturday mornings, […]

The U.S. government has set out to fast-track technology development enabling hydrogen and ammonia combustion in power-generating gas turbines, furnishing six novel industry-led projects with a combined $24.9 million on May 19. Projects include development of hydrogen-ready combustion technologies for F-class retrofits, more efficient hydrogen and ammonia burners, and a potential demonstration of a rotating […]
