The technology will be installed at Klickitat Valley Health’s facility in Goldendale, Washington State, to provide hydrogen to an existing stationary fuel cell system for critical back-up power.

A 100kW Rehklo stationary power generator, which uses fuel cell modules from Toyota, has been operating at the hospital since 2025 under a state and federally-backed trial for emergency backup power.

Jim Petrecky, CCO of Hydrexia, said the contract represents strong backing of the company’s product.

Hydrexia’s MHX technology stores hydrogen by absorbing it into a magnesium-based metal alloy from which it can be released when heated or depressurised.

The company argues it offers a safer, modular option for hydrogen storage than high-pressure cylinders, while avoiding boil-off losses associated with liquid hydrogen.

However, solid-state systems are significantly heavier. When factoring in container and system components, the practical storage capacity of a 100kg solid-state storage system comes to about 2–4kg of hydrogen, which can impact transportation costs.
