Is There A Working HiiROC Electrolyser in The United States?

I don’t know, but Google AI gave me this answer.

As of late 2026, there is no working or operational HiiROC electrolyser (Thermal Plasma Electrolysis plant) in the United States.

While the UK-based company has expanded its focus to the U.S. market—incorporating HiiROC USA in Delaware and working with the U.S. Department of Energy’s GREET model to calculate its carbon intensity—its active and pilot deployments remain concentrated in Europe and the United Kingdom.

Current HiiROC Projects & Status

Instead of U.S. facilities, HiiROC’s current physical footprint and major milestones include:

The Brigg Pilot Plant (UK): A demonstration facility built in partnership with Centrica at a gas-peaking plant in Lincolnshire, England, which represents their primary working test site.

Industrial Scale Deployments (UK): Scaled industrial rollouts, such as a major project at Cemex’s Rugby cement plant and a pilot facility at Saltend Chemicals Park in Hull.

Future Pipelines: The company has targeted commercial unit deployments starting in 2026, alongside feasibility studies for massive clean methanol and hydrogen plants in Scotland.

The U.S. hydrogen market currently relies heavily on other local producers (such as Monolith Materials for methane pyrolysis or Plug Power and Electric Hydrogen for water electrolysis), though HiiROC is actively building its in-country team to service future pipeline demand from U.S. customers.

You do wonder, if because of Trump, no American companies decided to get involved with HiiROC.
