GE Confirms Order of 1st Dual-Fuel H-Class Turbine in the World

Expanding on GE’s announcement of its 18th and 19th H-class gas turbine orders, the company has confirmed that the new 7HA.02 gas turbine to be installed at PSEG Power’s Sewaren 7 combined-cycle power plant in New Jersey will be the first H-class turbine in the world capable of dual-fuel operation.
In recent winter weather events, nearly a quarter of PJM installed capacity was unavailable due to natural gas supply constraints. To avoid such problems in the future, the Sewaren plant will be the first facility in the world to operate an H-Class turbine capable of burning both natural gas and ultra-low-sulfur distillate. Under normal circumstances, the turbine will rely on natural gas supplied by pipeline.  When these supplies are compromised, the plant will be able to switch to operation using backup fuel, an ultra-low-sulfur distillate trucked in and stockpiled as a liquid in tanks at the plant. Plants generally maintain 24 to 72 hours of backup distillate at the ready.
“One of GE’s real strengths is our wide fuels capability,” said Guy DeLeonardo, General Manager of High Efficiency Gas Turbines at GE Power & Water. “Our F-class turbines can burn multiple fuels, including light crude, and our H-class turbines further improve on this capability. Dual fuel capability gives customers operational peace of mind.”
GE’s HA turbine will also help lower the carbon dioxide (CO2) emissions rates at the Sewaren plant to nearly half that of a typical boiler, in the process satisfying the federal government’s 2030 Clean Power Plan mandates for New Jersey. Additionally, the turbine will be capable of faster startups, replacing four steam turbines in operation at the plant for nearly 70 years, and generating the same amount of power using half the fuel.
With the announcement of yesterday’s orders , GE now has 68 technical selections for H-class technology from projects in various stages of construction and commissioning in the U.S., Japan, UK, Brazil, Argentina, South Korea, France, Russia, Germany, Turkey, Egypt, and Pakistan.
“HA turbines are all about customer economics,” says DeLeonardo. “That’s good for generators, governments, and rate payers.  GE builds the biggest machines to drive the lowest dollar per kW, which helps out both the power producer and the rate payer. What’s more, all GE’s turbines are highly reliable. A car that gets great gas mileage is useless if it’s in the shop every week.”
