Green Hydrogen International and Hydrogen Optimized to build electrolyzer factory in Texas

The facility will supply GHI’s Hydrogen City project in South Texas.

Green Hydrogen International (GHI) and Hydrogen Optimized, a subsidiary of Key DH Technologies Inc., have signed an MoU for the proposed development of a large electrolyzer manufacturing facility in Texas.

The factory will produce Hydrogen Optimized’s RuggedCell™ water electrolyzers for GHI’s planned Hydrogen City project, a previously announced 60 gigawatt (GW) green hydrogen production and salt cavern storage hub to be built in South Texas.

The proposed RuggedCell™ manufacturing facility will be built out in stages, with an ultimate target of 5 GW a year of electrolyzer production. GHI intends to purchase the facility’s entire output for the first 10 years of operation to supply its Hydrogen City project. Locations being considered for the factory to include the Austin, Houston, Dallas, and Corpus Christi areas.

GHI’s gigawatt-scale green hydrogen production plan requires very large-scale water electrolysis technology. Hydrogen Optimized’s patented high-current RuggedCell™ technology was designed from the first principles for large-scale hydrogen production at a significantly lower capital cost. The company is targeting individual RuggedCell™ installations of 100 MW as a stepping-stone to systems up to 400 MW.

By comparison, most systems available in the market today cannot scale beyond 20 MW per unit or, in many cases, 5 MW per unit. Furthermore, unlike the RuggedCell™, many of these systems use expensive iridium, which is not available at a volume required to meet the multi-gigawatt annual global demand for electrolyzers. Another key advantage of the RuggedCell™ is its dynamic response to variations in electrical current levels from 0 to 100% power load in just a few seconds.

Brian Maxwell, GHI Founder and CEO, noted, “Andrew Stuart and his team at Hydrogen Optimized have unmatched experience and technology expertise in green hydrogen production, and we’re proud to be working with them to develop the world’s largest green hydrogen production and storage hub in Texas.”

Andrew T. B. Stuart, President and CEO of Hydrogen Optimized, said, “We’re particularly excited to explore GHI’s plan to store green hydrogen in salt caverns, an approach that inherently recognizes the need to produce and store green hydrogen on a massive scale to unlock a region’s renewable energy potential and drive the transition to clean energy.”

Andy Steinhubl, HI Board member, commented, “Hydrogen Optimized shares our vision of the role of gigawatt-scale production as an imperative to meet global cost and volume requirements for green hydrogen, and we’re excited to work with them on scaling up critical electrolyzer production capacity in Texas.”
