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.

What customers say about us

''We could not be more pleased with the outcome of this project. The comparatively low cost of green hydrogen that GHS is able to deliver has opened the door to significant environmental benefits for our community.''
Christian Twitchett
Department of Public Transportation and Mobility in Denmark’s North Jutland region
''Green Hydrogen System’s electrolysers and on-site production approach have enabled us to start meeting our customers’ demand for solar-produced hydrogen''
Hans-Olof Nilsson
Nilsson Energy, Sweden

At Green Hydrogen Systems, my colleagues and I are convinced that green hydrogen will be at the heart of the future energy systems – and we are committed to be on the forefront of this energy transition.
