Duke Power, GE Vernova, and Sargent and Lundy will staff on a pioneering undertaking to show an end-to-end power system that produces, shops, and combusts 100% renewable hydrogen at Duke Power’s DeBary photo voltaic plant in Florida.
Duke Power on Oct. 27 stated building on the undertaking, a “one-of-a-kind end-to-end” system, will start later this 12 months and could possibly be put in and totally functioning in 2024.
The demonstration contains two elements: It can supply hydrogen from a facility deliberate on the 74.5-MW Debary plant in Volusia County, a 2020-opened facility that options 300,000 photo voltaic PV panels. The hydrogen manufacturing plant, which is able to make the most of energy from the photo voltaic facility, will run two 1-MW electrolyzer models.

The renewable hydrogen will then be delivered to “close by, bolstered containers for secure storage.” Nonetheless, throughout occasions when power demand is highest, the built-in system will function a devoted “peaking” facility, delivering saved hydrogen to a combustion turbine (CT) that will probably be upgraded utilizing GE expertise to combust a pure fuel/hydrogen mix or as much as 100% hydrogen. “This would be the nation’s first CT in operation operating on such a excessive proportion of hydrogen,” Duke Power stated.
A Mission to Show Hydrogen’s Dispatchable Energy Function
The undertaking marks a pivotal juncture in U.S. energy industry-led efforts to develop carbon-free dispatchable power sources. Duke Power, in an announcement on Friday, underscored hydrogen’s rising position. “Available hydrogen is a dispatchable power supply, that means it’s accessible on demand. It may be turned on and off at any time and isn’t depending on the time of day or the climate, like solar, wind or different renewable power sources referred to as intermittent.”
“Duke Power anticipates hydrogen might play a significant position in our clear power future,” stated Regis Repko, senior vice chairman of technology and transmission technique for Duke Power. “Hydrogen has important potential for decarbonization throughout all sectors of the U.S. economic system. It’s a clear power additionally able to long-duration storage, which might assist Duke Power guarantee grid reliability as we proceed including extra renewable power sources to our system.”
As well as, by introducing the nation’s first end-to-end system, the undertaking is meant to supply an answer to one of many renewable power sector’s most urgent challenges: guaranteeing constant power provide even when the solar’s power is diminished whereas optimizing photo voltaic power sources for prolonged intervals of excessive demand. “Counting on intermittent power sources with out accessible dispatchable power sources would put our future electrical system susceptible to having inadequate power to serve buyer demand,” Duke Power stated.
The {industry} collaboration behind the undertaking can also be notable. Duke Power, the nation’s greatest utility, has explored a number of choices as a part of a sustainable technique to realize a “net-zero” goal, aiming to supply zero carbon emissions from electrical technology by 2050. Sargent and Lundy, a number one engineering, procurement, and building contractor, and GE Vernova, an authentic gear producer and a significant worldwide participant within the fuel turbine market, are deeply entrenched in efforts to allow clients to realize decarbonized operations.
Related Effort at HYFLEXPOWER in Europe
The demonstration, the primary of its sort within the U.S., notably follows related efforts all over the world. Earlier this month, HYFLEXPOWER, a European Union-backed industrial-scale demonstration of built-in hydrogen power-to-power, powered its Siemens Power SGT-400 fuel turbine with 100% renewable hydrogen.
The achievement is a leap for HYFLEXPOWER, a four-year CORDIS undertaking that seeks to show the complete power-to-hydrogen-to-power chain for industrial operations, together with the manufacturing, storage, and re-electrification of hydrogen. The undertaking has been ongoing since June 2020 at a transformed 12-MWe mixed warmth and energy (CHP) at Engie Options’ Smurfit Kappa pulp-and-paper industrial web site in Saillat-sur-Vienne, France.
As POWER has reported, the 2007-installed CHP facility makes use of a Siemens Power SGT-400 fuel turbine and a restoration boiler to supply energy. It additionally produces steam, which the Smurfit Kappa paper mill makes use of to dry pulp from the recycling of waste paper to make new paper for cardboard. HYFLEXPOWER produces hydrogen by way of a 1-MW electrolyzer onsite and shops the hydrogen in an “nearly one-ton tank” earlier than it’s used to energy the Siemens Power SGT-400 industrial fuel turbine.
SGT-400 industrial generators usually use G30 burner expertise, a confirmed radial swirler premixing design that enables for gas flexibility and might function as much as a ten% hydrogen mix. At HYFLEXPOWER, the turbine integrates dry-low emissions (DLE) combustion expertise, developed via a devoted analysis and expertise program
