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 with industrial partners.

The Challenge in Green Hydrogen

Critical Material Dependence:High iridium costs and limited supply constrain PEM scalability and long-term affordability.Durability vs. Efficiency:Current low-PGM catalysts often struggle to balance stability, performance, and cost.Urgent Market Need:GW-scale green hydrogen requires scalable, cost-efficient, high-performance catalysts that drastically reduce or eliminate critical raw materials.

Our Technology

Atomic-Level control

We design nanocatalysts with tailored size, shape, composition, and electronic structure to maximize surface reactivity and stability.

80% Less Iridium

Our PEM OER catalysts target ≥90% reduction in iridium use while preserving industrial durability and performance targets.

Lab to Stack

Rapid in-house validation using electrochemical cells and lab-scale electrolyzers accelerates learning cycles and scale-up.

Development Roadmap

Phase 1 - Iridium-Light PEM CatalystsCut iridium use by ≥80% at stack level while preserving industrial durabilityPhase 2 - PGM-Free AEM CatalystsEliminate precious metals entirely from alkaline membrane systems.Phase 3 - Plasmonic-Enhanced CatalystsIntegrate plasmonic-enhanced catalysts to achieve breakthrough efficiency improvements.
