Gas power market drivers and a quest for relevance in future decarbonized systems are driving fundamental shifts in gas turbine combustion design approaches. Combustion lies at the heart of gas turbine

Flexible plant operations are highly desirable in today’s power generation industry. Every plant owner desires increased ramp rates and the ability to operate at lower loads so their plants will remain “in the money” longer in today’s competitive power markets. This goal, while laudable, remains elusive. The ADEX self-tuning artificial intelligence (AI) system allows plants […]

Mitsubishi Power is developing a 40-MW class gas turbine that can directly combust 100% ammonia under an initiative that responds to heightened global decarbonization ambitions, as well as Japan’s recent roadmap for ammonia fuel.  The Yokohama–headquartered power equipment firm, a subsidiary of Mitsubishi Heavy Industries (MHI), on March 1 said it is targeting commercialization of […]

Iberdrola SA and Mitsubishi Hitachi Power Systems (MHPS) recently commissioned the El Carmen combined cycle plant, located in Nuevo León, northeast Mexico.

Entergy Corp., an integrated energy company with a 30-GW power generating fleet, took a bold step toward decarbonization on Sept. 23, announcing it would join forces with Mitsubishi Power to integrate green hydrogen into utility businesses in Arkansas, Louisiana, Mississippi, and Texas.  Entergy will focus on developing hydrogen-capable combined cycle gas turbine (CCGT) facilities and […]

Distributed generation integrated with intermittent renewable generation responds to the growing need for highly flexible small-scale (less than 100 MW) power generation resources. The limiting factor facing plant designers is that the conventional heat recovery steam generator (HRSG) does not enable fast-acting power generation demanded by modern grid systems. John Cockerill Energy’s vertical once-through boilers […]

Three major gas-fired power projects—a total of 2.1 GW—in Eastern competitive markets that are slated to come online between 2023 and 2025 have chosen hydrogen pathways to ensure their long-term viability as states increasingly emphasize energy system decarbonization.  The plants, which represent a total investment of $3 billion, will adopt integrated green hydrogen solution packages […]

The first GE 7F gas turbine began commercial operation 30 years ago this month. Since coming on the market, more than 950 7F machines have been commissioned, including four 7F.04 units that entered service recently at Techint’s Norte III combined cycle power plant in Mexico. The 907-MW Norte III facility is located in the municipality […]

Hit hard by response to the COVID-19 pandemic, global gas demand in 2020 is set to to tumble by twice the amount lost after the 2008 global financial crisis—its largest annual decline in history—the International Energy Agency (IEA) says in its latest annual market report Gas 2020.  As of June 2020, the fall has been […]

Siemens Energy completed “first fire” at Duke Energy’s Lincoln Combustion Turbine Station near Denver, North Carolina, on April 6. The accomplishment is a major milestone for the world’s first SGT6-9000HL gas turbine, confirming the engine and auxiliary systems, including the gas supply, lube oil system, control system, and startup systems, all work as designed. During […]

Mitsubishi Hitachi Power Systems (MHPS) has bagged an order for the first advanced-class gas turbines designed to transition to renewable hydrogen fuel from Utah’s state-owned Intermountain Power Agency (IPA). MHPS’s Lake Mary, Florida–based subsidiary MHPS Americas (MHPSA) on March 10 said that the contract for two M501JAC power trains are the first in the industry […]

Given current trends, the U.S. gas turbine industry is set to play a critically important role in power generation, aircraft propulsion, and the oil and gas industry “for decades to come,” but it could benefit from prioritized research and development (R&D) and technological leadership, a new report from the National Academies of Sciences, Engineering, and […]
