The Road To Green Hydrogen Is Paved With Deuterium

The cancellation of the Biden-era Regional Clean Hydrogen Hubs program has created uncertainty in the US green hydrogen sector, though technological advances and emerging business models continue to attract interest. The program, funded through the 2021 Bipartisan Infrastructure Law, aimed to accelerate hydrogen production from renewable energy and other alternative sources to replace the current reliance on natural gas and coal-derived hydrogen across industries including refining, metallurgy, pharmaceuticals, and food processing.

Aternium, a startup focusing on hydrogen production, has announced plans to construct its first facility at Garrison Oak Technical Park in Dover, Delaware, pending property acquisition later this year. The facility will produce both green hydrogen and deuterium oxide, a byproduct with significant applications in pharmaceuticals, semiconductors, advanced electronics, nuclear energy, and emerging fusion technologies. The company plans to power operations exclusively through renewable electricity, utilizing the solar infrastructure at the site while planning future expansion into wind and solar capabilities across Delaware, New Jersey, and Pennsylvania.

The timing of Aternium’s expansion into the mid-Atlantic region reflects existing renewable energy infrastructure and prospects in the area. Maryland’s offshore wind project and Virginia’s coastal wind initiative have continued despite recent political headwinds, while Pennsylvania presents a mixed landscape with gas industry influence in its western regions but renewable-oriented initiatives in the east. The MACH2 hydrogen hub, which was expected to receive federal support, has reportedly received only a fraction of anticipated funding, yet Aternium has indicated it does not depend on such subsidies for viability.

The company’s approach underscores the emergence of market-driven solutions in the green hydrogen space, even as federal policy support remains constrained. By focusing on the co-production of high-value deuterium oxide alongside green hydrogen, Aternium aims to achieve competitive pricing while addressing demand for domestically produced heavy water, which currently relies on foreign sources for strategic US industries.
