ThermH2 celebrated a significant milestone with a ribbon-cutting ceremony for its hydrogen blending project, using an innovative electrolyzer to create green hydrogen and blend it with natural gas, reducing emissions and promoting sustainability.

Delta, Utah, a town celebrated for its natural beauty, rich history, and vibrant community spirit, was the site of a historic moment last week. Therm H2, Dominion Energy Utah (DEU) hosted a ribbon-cutting ceremony focused on the on-site arrival of the electrolyzer, an innovative technology that will allow the company to create hydrogen. DEU is one of the few utilities in North America to blend hydrogen into a live system and is one of the few companies using an electolyzer to create hydrogen on-site.

The electrolyzer will begin creating green hydrogen in late fall using water and renewable feedstocks. DEU will then integrate the hydrogen into the natural gas supply at a 5% blend, serving approximately 1,800 customers in Delta and neighboring communities. This phase of the project follows a year of extensive research at DEU's Training Academy in Salt Lake City to confirm industry research. Following the work done at the Academy, the company began blending hydrogen in late March of 2023 using pre-produced hydrogen in tanks. The introduction of hydrogen made on-site will further the phase and help reduce emissions even further.

By blending at a 5% rate, Delta is estimated to save around 110 tons of carbon emissions each year, equivalent to taking 24 cars off the road or planting 5,000 trees annually!

Alyssa Wahlin, a research and development engineer for the project, explained, “Hydrogen doesn't have carbon emissions, and if produced through renewable means, it reduces emissions in our natural gas system. We're among the first companies doing this at this scale, and it's exciting.”

Reflecting on the project's journey, Judd Cook, GM and VP of Western Gas Distribution for Dominion Energy Utah, said, “Five years ago, I proposed blending hydrogen into natural gas. It felt aspirational, and Craig Wagstaff said ‘Make it happen.’ We formed a team, crafted a vision, and handed it to the experts. They turned a dream into reality. We have great people who made it happen.”

While there has been much progress, Cook is excited to see how this project progresses. “We're trying to do something truly sustainable by lowering our carbon footprint and finding cost-effective solutions.”

Andrew Hegewald, Dominion's gas business development manager, summed it up, “One small step for hydrogen blending, one giant leap for Dominion Energy.”

Dominion Energy Employees at Delta, Utah Hydrogen Building Project Ribbon Cutting CeremonyThe event featured several speakers, including Delta's Mayor John Niles, Harry Hansen, Deputy Director of the Office of Energy Development, Cook, and Hegewald. They emphasized hydrogen's potential as a clean, versatile energy source capable of decarbonizing various sectors.

Guests explored the ThermH2 project and the electrolyzer technology through guided tours of the facility.

The day drew an esteemed gathering, including local leaders/city officials, Dominion Energy employees, state and local leaders, and media, all eager to witness this groundbreaking step into the future of energy.

Delta Mayor John Niles expressed his enthusiasm, saying “This was years in the making, and the collaboration between Dominion and Delta will be one for many years to come.”

With the ThermH2 project, DEU stands as a trailblazer in North America, successfully demonstrating the possibilities of blending hydrogen into live energy systems and pioneering on-site hydrogen production through renewable means. The ribbon cutting in Delta, Utah, is a testament to the boundless potential of clean energy and the promise of a greener, more sustainable future.
