MMatteco
Matteco is a Valencian deeptech company that develops platinum- and PGM-free catalysts, catalytic coatings and electrodes for green hydrogen production via alkaline (AWE) and anion exchange membrane (AEM) electrolysis, claiming up to ~30% lower energy consumption. Founded in 2023 as a spin-off of the University of Valencia's Institute of Molecular Science (ICMol) and built by impact venture builder Zubi Labs, it raised a €15M Series A in October 2024 to open a 10,000 m² advanced materials factory in Paterna (Valencia) capable of supplying electrodes for 1 GW of electrolysis a year. It already ships to customers in Europe, North America and Asia and won the 2024 Cinco Días Business Innovation Award.

SStargate Hydrogen
Estonia · stargatehydrogen.com ↗
Built on its own precious-metal-free ceramic catalysts and electrodes for alkaline electrolysis, but it sells the catalyst layer packaged inside its own electrolyser stacks, not as a stand-alone component.
~$55MComparable
IIonomr Innovations
Canada · ionomr.com ↗
Makes an advanced-materials component (ion-exchange membranes and polymers) for AEM electrolysers and fuel cells, sold to stack makers instead of building electrolysers itself.
~$40MComparable
VVersogen
United States · www.versogen.com ↗
University spin-out that commercialises AEM electrolysis materials (anion exchange ionomers and membranes) that let electrolysers run without platinum-group metals.
~$15MComparable
HH2U Technologies
United States · www.h2u.io ↗
Uses AI to discover low-cost catalysts free of platinum-group metals for water electrolysis and supplies the catalyst and electrode materials to the green-hydrogen industry.
