About ReLight
Origin
ReLIGHT is a Research-to-Business project from the University of Helsinki, building next-generation catalysts for PEM and AEM electrolysis.
Mission
To eliminate critical material bottlenecks and accelerate green hydrogen deployment through iridium-light and PGM-free nanocatalysts.
Status
Pre-spinout stage, based in Helsinki, Finland. Preparing for pilot scale-up and commercialization.
The Challenge in Green Hydrogen
Critical Material Dependence:High iridium costs constrain PEM scalability and long-term affordability.Durability vs. Efficiency:Current low-PGM catalysts struggle to balance stability with performance.Urgent Market Need:Scalable, cost-efficient, high-performance catalysts—free from critical raw materials—are essential for hydrogen’s global future.
Our Technology
Atomic-Level control
We design nanocatalysts with tailored size, shape, and electronic structure to maximize surface reactivity and stability.
50% Less Iridium
Our PEM catalysts reduce iridium use by half while maintaining durability targets.
Lab to Stack
Rapid in-house validation using electrochemical cells and lab-scale electrolyzer stacks accelerates scale-up.
Development Roadmap
Phase 1 - Iridium-Light PEM CatalystsCut iridium use by ≥50% while preserving industrial durabilityPhase 2 - PGM-Free AEM CatalystsEliminate precious metals entirely for alkaline membrane systems.Phase 3 - Plasmonic-Enhanced CatalystsIntegrate plasmonic-enhanced catalysts to achieve breakthrough efficiency improvements.
