Catalyzing the Hydrogen Economy

A clean energy future is here

H2U Technologies is a developer of low-capital-cost, iridium-free proton exchange membrane (PEM) electrolyzers that are particularly suited for pairing with renewable energy sources. We leverage our ultra-high speed Catalyst Discovery Engine™ (CDE™) to develop low cost non-PGM catalysts for use in our electrolyzer systems. The world-class technology featured in our products stems from ten years of research and development at Caltech, funded by the U.S. Department of Energy.


The problem the world is facing now is a barrier to scale of electrolyzers that rely on precious metals

Today: Iridium $5600/toz, Platinum $1280/toz = 20%+ of  Electrolyzer cost by 2030 assuming NO price increases !

The world is rapidly adopting green hydrogen as the clean energy carrier for decarbonizing global industries across the board – transportation, energy, metals, chemicals, construction, and others comprise the vast majority of carbon emitting industries.  Today, using hydrogen for decarbonization depends on rare, expensive precious metals used as catalysts for producing clean hydrogen and converting it to clean power.

H2U discovers and commercializes abundant inexpensive catalysts enabling the world to


H2U electrocatalyst discovery is an unprecedented, proprietary, end-to-end ultrahigh throughput AI and data-driven process focused on discovery of new catalysts for generation of clean hydrogen and fuel cell power production.  The process prepares, characterizes, and quantifies the catalytic activity of tens of thousands of compositions per month and then closes the loop with big data analysis and AI to refine/guide the search.  

H2U Gramme 50 Electrolyzer

The Gramme 50 GS series PEM Electrolyzer is a novel and disruptive design,

made to drive rapid and large scale adoption of grid scale electrolysis.


Advantages of the

PEM (proton exchange membrane) Electrolyzer

Iridium-free PEM electrolyzer technology H2U’s low-cost PEM electrolyzers leverage novel, noniridium catalysts and innovative electrolyzer design improvements to enable cost-effective green hydrogen generation. Our 200 kW Yellowstone electrolyzer units come in plug-and-play, standard shipping containers. These scalable modules are well-suited to help decarbonize businesses over a range of applications.

How do we get there? CDE for PEM electrolyzers

Our CDE is a data-driven, rapid-screening process that allows scientists to make, characterize, and quantify the catalytic activity of thousands of material compositions per week. In the coming years, highly constrained sources of PGM materials will lead to product shortages and electrolyzer price increases.

Using its patented CDE technology, H
2U Technologies has discovered novel, non-iridium catalyst materials that have been validated both in-house and through third-party testing by the #1 global supplier of catalytic coatings.

Products for a
better world

Hydrogen compression, storage and transportation costs can double production costs. H2U minimizes these costs by designing electrolyzers specifically tailored for on-site production of hydrogen.

Applications for our pilot products include natural gas blending, hydrogen fueling stations, steel production, and green ammonia production.
