ULC-Energy, a nuclear development and consultancy company based in the Netherlands, has signed a memorandum of intent with Danish carbon emission reduction technology firm Topsoe and Britain’s Rolls-Royce SMR to investigate the production of hydrogen using Topsoe’s solid oxide electrolysis cell (SOEC) technology and electricity and heat from a Rolls-Royce small modular reactor plant.

The Department of Energy yesterday announced the awarding of $22.1 million to 10 industry-led nuclear projects, including two aimed at expanding clean hydrogen production and one at advancing a microreactor design. Other projects selected for funding are focused on addressing nuclear regulatory hurdles, improving existing reactor operation, and facilitating new advanced reactor developments.

Abstracts for all 10 projects can be found here.

On December 20, 1951, researchers used energy produced by Experimental Breeder Reactor-I near Arco, Idaho, to illuminate four 200-watt lightbulbs. Since then, utilities have built commercial nuclear power plants in the United States almost exclusively to generate electricity. This has worked well alongside other power generation and transmission infrastructure—large oil- and coal-fired, natural gas turbine or hydroelectric plants, and a relatively simple electrical grid designed to deliver reliable power.

Humanity is now embarking on an epic and complex energy transformation across the grid, industry, and transportation. Renewables like wind and solar are contributing an increasing share of carbon-free electricity to the grid, but that contribution is variable and hard to predict—sometimes those sources produce more electricity than the grid needs, and sometimes less.

Seattle’s Ultra Safe Nuclear (USNC) has announced a partnership with two South Korean firms—Hyundai Engineering and SK ecoplant—for research and development on carbon-free hydrogen production. The three companies signed a memorandum of understanding on April 20 regarding the construction of a “hydrogen micro hub” at SK ecoplant’s headquarters in Seoul’s Jongno-gu district.

U.S. special envoy for climate John Kerry and Ukraine’s minister of energy German Galushchenko have announced a two-to-three-year pilot project aimed at demonstrating the commercial-scale production of clean hydrogen and ammonia from small modular reactors in Ukraine using solid oxide electrolysis.

Using nuclear power technology to produce clean hydrogen is getting a visibility boost as the Department of Energy hosts a virtual three-day (June 6–8) Annual Merit Review and Peer Evaluation Meeting on the agency’s efforts to accelerate clean hydrogen production. On June 6, the DOE announced a notice of intent (NOI) to fund the Bipartisan Infrastructure Law’s $8 billion program to develop regional clean hydrogen hubs (H2Hubs) and the launch of a new Hydrogen Shot Incubator Prize that seeks “disruptive technologies” to reduce the cost of clean hydrogen production. That same day, Westinghouse Electric Company and Bloom Energy Corp. (a maker of solid oxide electrolyzer technology) announced a letter of intent to develop electrolyzers for use in the commercial nuclear power market and said they are “well positioned to support the U.S. Department of Energy’s developing hydrogen hubs.”

The U.K. government last week announced the release of its UK Hydrogen Strategy, predicting thousands of jobs and billions of pounds in investment and export opportunities over the coming decades via the creation of a low-carbon hydrogen sector in Britain.

A flourishing, U.K.-wide hydrogen economy could be worth £900 million (about $1.2 billion) and create over 9,000 high-quality jobs by 2030, according to the government, potentially rising to 100,000 jobs and worth up to £13 billion (about $18 billion) by 2050.

A bipartisan trio of House members from Pennsylvania last week introduced legislation to accelerate research and development, as well as deployment, of hydrogen from clean energy sources.

Hydrogen can be produced from a variety of domestically available clean sources, notes the Clean Hydrogen Energy Act, including nuclear power, renewables, and fossil fuels with carbon capture, utilization, and storage.

Reps. Mike Doyle (D., Pa.), Brian Fitzpatrick (R., Pa.), and Conor Lamb (D., Pa.) sponsored the measure.

Nuclear power could produce as much as one-third of the United Kingdom’s clean hydrogen needs by 2050, posits the Hydrogen Roadmap, a 12-page report recently approved by the Nuclear Industry Council (NIC) and released last week by the Nuclear Industry Association (NIA).

The NIC, co-chaired by the British government’s minister for business, energy, and clean growth, and the chairman of the NIA, sets strategic priorities for government-industry collaboration to promote nuclear power in the United Kingdom.

The road to net zero: The report outlines how large-scale and small modular reactors could produce both the power and the heat necessary to produce emissions-free, or “green,” hydrogen. Existing large-scale reactors, it says, could produce green hydrogen today at scale through electrolysis, as could the next generation of gigawatt-scale reactors. Also, according to the report, SMRs, the first unit of which could be deployed within the next 10 years, could unlock possibilities for green hydrogen production near industrial clusters.

The Department of Energy released a Hydrogen Program Plan on November 12 that provides a strategic framework for the agency’s hydrogen research, development, and demonstration activities.

The DOE’s Offices of Nuclear Energy, Energy Efficiency and Renewable Energy, Fossil Energy, Electricity, and Science, and the Advanced Research Projects Agency–Energy are all working on the production, transport, storage, and use of hydrogen in several sectors of the economy and have developed technical and programmatic multi-year plans. The Hydrogen Program Plan coordinates and complements those efforts by presenting a strategic direction that highlights the importance of collaboration both within DOE and with stakeholders in industry, academia, and the states.

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.

New Orleans–based Entergy Corporation last week announced a commitment to achieve net-zero carbon emissions by 2050, joining a growing list of major energy companies to make that promise—including Dominion Energy, Duke Energy, Southern Company, Xcel Energy, and Public Service Enterprise Group. And, like those companies, Entergy says that it sees nuclear playing an important role in the realization of that goal.
