Clean energy technology firm Bloom Energy has announced plans to install a 240-kW electrolyzer at Xcel Energy’s Prairie Island plant in Red Wing, Minn., to demonstrate the benefits of producing hydrogen with nuclear power. (One of Xcel’s two nuclear plants, Prairie Island houses twin 550-MWe pressurized water reactors.)

NuScale, Xcel agree to explore future partnerships

NuScale Power has signed a memorandum of understanding with Xcel Energy to explore the feasibility of the utility’s serving as a plant operator at NuScale plants, the Portland, Ore.-based small modular reactor developer announced earlier this week.

Xcel owns and, through subsidiary Northern States Power Company, operates Minnesota’s two nuclear plants, Monticello and Prairie Island. The Monticello facility houses one 671-MWe boiling water reactor, while Prairie Island has twin 550-MWe pressurized water reactors.

Xcel Energy’s Prairie Island likely hydrogen demo site

Xcel Energy’s Prairie Island is the probable location for the nation’s first demonstration of high-temperature steam electrolysis at a nuclear power plant. Idaho National Laboratory, which plays a key role in a hydrogen demonstration project launched last year with Xcel Energy, Energy Harbor, and Arizona Public Service (APS), announced on November 9 that Prairie Island, which houses two 550-MWe pressurized water reactors, would likely be chosen over the one-unit boiling water reactor plant at Monticello.

Minneapolis-based Xcel Energy will work with INL to demonstrate a system that uses the plant’s steam and electricity to split water. The resulting hydrogen will be used at the power plant, but excess hydrogen could be sold to other industries. Hydrogen has applications in transportation and in industrial sectors, including steel and ammonia production.

More than $10 million in federal funding for the Xcel Energy demo was announced by the Department of Energy on October 8. It is just one phase of a project that showcases collaboration between the DOE’s Office of Nuclear Energy and Office of Energy Efficiency and Renewable Energy. Commercial hydrogen production via low-temperature electrolysis is being demonstrated at Energy Harbor’s Davis-Besse plant. APS, which operates the Palo Verde generating station, will build on the Xcel Energy demo to develop an initial design and feasibility assessment for plant modifications to integrate a reversible hydrogen electrolysis system with the plant’s secondary system and will include hydrogen storage infrastructure.
