Adele Hydrogen

What Adele Hydrogen does

Adele Hydrogen develops alkaline electrolyzer electrode technology for green hydrogen production. The company focuses on Pathfinder Electrodes, which increase active surface area, lower stack power consumption, and raise hydrogen output per square meter. Its electrodes aim to cut energy use, improve current density, and expand turndown ratios for systems powered by variable renewables. Adele Hydrogen collaborates with electrolyzer OEMs, research laboratories, and project developers on performance testing and deployment. It serves industrial hydrogen producers seeking to lower production costs and capital needs while integrating into existing alkaline systems.

Core offering

Adele Hydrogen develops and manufactures Pathfinder Electrodes — proprietary alkaline electrolysis electrodes built with patented non-Platinum Group Metal (non-PGM) catalysts on a catalyst-coated substrate. The electrodes deliver up to 10,000x active surface area versus standard electrodes, up to 69% LHV efficiency meeting IEA 2030 targets, and integrate directly into existing alkaline electrolyzer stacks without modification. Manufacturing is being scaled at the Alpha Line facility in Lyon (launch H1 2026) targeting hundreds of MW of annual electrode output for OEM and industrial hydrogen customers.

Product overview

Adele Hydrogen offers a single unified product line centered on its Pathfinder Electrodes — advanced alkaline electrolysis electrodes for green hydrogen production. The electrodes feature proprietary patented catalysts, achieve industry-leading efficiency (up to 69% LHV), and operate without Platinum Group Metals or Critical Raw Materials. The technology integrates into existing alkaline electrolyzer systems without modifications, targeting both CAPEX reduction (up to 80% stack savings) and OPEX reduction (42.5 kWh/kg energy consumption). The company is establishing the Adele Hydrogen Alpha Line production facility in Lyon (launch H1 2026) to produce hundreds of MW of electrodes annually.
