Green hydrogen and electrolysis

Identify earth-abundant HER and OER catalyst candidates with computed ΔG values, patent landscape context, and viable synthesis routes — all in one governed workflow.

Best-fit teams

Electrolyzer R&D, PEM and AEM membrane teams, stack and systems engineering, green hydrogen project developers

Typical questions
Which earth-abundant phosphides, carbides, or nitrides sit closest to the HER volcano peak?
Which compositions are thermodynamically stable, synthesizable, and without identified patent coverage?
What is the supply concentration risk for the critical elements in our leading catalyst candidates?
Where teams get stuck

The decision gap this page is built for

Hydrogen catalyst discovery is slow because teams search adsorption data, patent claims, and synthesis recipes in three separate systems — missing non-obvious candidates and re-discovering known dead ends.

How Lattice Graph helps

Capabilities aligned to this workflow

Run HER/OER volcano positioning across 200K+ catalyst surfaces to find near-optimal candidates
Screen indexed patent data to identify earth-abundant systems with apparent coverage gaps
Check synthesis feasibility against 38K experimental recipes before lab commitment
Decision flow

A typical way teams use the platform here.

01

Map the catalyst landscape

Volcano plots position every candidate on HER, OER, or CO₂RR activity maps — surfacing under-investigated material families near the activity peak.

02

Validate synthesis routes

Check whether shortlisted catalysts have documented synthesis routes in the recipe corpus before investing lab resources.

Signals in scope

What teams usually need in one screen.

ΔG_H and volcano proximity for HER/OER activity
Patent whitespace across 306K patents
Synthesis recipe count and process conditions
Supply chain criticality for catalyst elements
Expected outcome

Surface credible HER and OER catalyst candidates with clearer patent-landscape context and viable synthesis paths.
