Project with Alliander

A large-scale Power-to-X pilot project

Alliander, a Dutch energy company, chooses Green Hydrogen Systems (GHS) to supply the electrolysers for a large-scale Power-to-X pilot project in the Netherlands.

The project is located at the Ecomunitypark in Oosterwolde, and is operated in collaboration with solar-farm developer GroenLeven. The project will use electrolysers to convert excess solar or wind energy into hydrogen. The converted green hydrogen will then be stored and sold for use in transportation, industry, heating and other sectors.

Initially, the contract covers the supply of three standardised GHS HyProvide™ A90 electrolysers with a combined capacity of 1.4 MW. The hydrogen produced will be compressed and stored at 300 bar in a tube trailer for later use. As GHS electrolysers are standardised units that can be combined for multi-MW production, Alliander will be able to meet any subsequent need to scale by adding additional HyProvide™ units to the initial cluster of three.

Electrolysis equipment for every scale


HyProvide™ A-Series

Available in standardised, modular configurations for maximum efficiency, versatility and scalability, this next-generation technology makes the A-Series one of the most efficient alkaline electrolysers on the market. The unit is designed from the ground up to accommodate the input fluctuations that come with renewable energy sources. Its versatile design allows for application across many different market segments for green hydrogen production.

HyProvide™ X-series

The X-Series is based on the existing well-proven technology, optimised for use in the growing market for large-scale applications in, for example, industry, energy and heavy-duty transport sectors. Its unique multi-stack concept allows the electrolyser to reach higher voltages crucial to utilise mass-produced, low-cost and high-efficiency power electronics from wind and solar markets operating in the 1000-1500V range.
