Who’s working on clean hydrogen?
Clean hydrogen depends on electrolyzers that last, catalysts that use less precious metal, and membranes that hold up in operation. This page shows how much of that work the Helikon Research Graph holds and gives you a problem statement to run in Partner Search.
What the Helikon Research Graph holds on clean hydrogen
9,700+
researchers
30,000+
publications
1,400+
U.S. patents
Counts from the Helikon Research Graph on 9 October 2026; rounded down. Each figure is counted on its own, so they are not added together.
How these were counted
- Publications: papers whose title, author names or research topics match the keyword set below, the same text the Literature search reads.
- U.S. patents: granted U.S. patents whose text matches the keyword set and that carry at least one of these CPC subclasses: C25B, C01B, B01J. That is the Patents search with the CPC subclass field set.
- Researchers: people in the graph who authored a matching publication or are named inventors on a matching patent.
- Keyword set:
"clean hydrogen" OR "green hydrogen" OR "hydrogen production" OR "water electrolysis" OR "water splitting" OR "electrolyzer" OR "electrolyser" OR "PEM electrolysis" OR "proton exchange membrane electrolysis" OR "anion exchange membrane electrolysis" OR "solid oxide electrolysis" OR "oxygen evolution reaction" OR "hydrogen evolution reaction"

Partner Search ranks researchers against a problem statement by what their publications, patents and profiles say. This one is ready to run; edit it to fit your project.
We're scaling PEM electrolysis and need to cut iridium loading on the anode without losing durability. Looking for a group with OER catalysts and accelerated stress testing.Run this in Partner Search
Who’s working on this
Electrochemistry, catalysis and materials groups at universities, national laboratory hydrogen programs, and company teams building electrolyzers, catalysts and membranes. Many of the same electrochemists also work on batteries and fuel cells.
