Gateway Electrolysers


  • Modular turn-key systems

  • 1 – 10 MW

  • Leading warranty on the market

  • Dynamic operation for RES

Gateway electrolysers are containerised turn-key green hydrogen production systems using alkaline technology, that has a proven track record of long operational lifespans, which makes them a reliable choice for continuous hydrogen production. This durability minimizes downtime and maintenance costs, contributing to the economic feasibility of green hydrogen. The technology has been validated by several institutions including the Fraunhofer Society.

Each 40ft container consumes 1 MW of electricity and produces 200 Nm³/h of hydrogen, pressurised to 30 bar as output. The systems can be ordered with a 12-month lead time and come with an industry-leading performance guarantee. The electrolysers are highly suitable for a wide range of applications such as chemical feedstock, process heat, blending, transport fuel and energy storage.

Starbase Electrolysers

The Starbase Electrolyser series is not yet available for the market, it is still under development and will be launched soon.

Starbase electrolysers are large-scale skid-mounted systems built around our 10 MW pressurised alkaline stacks.

With a larger stack the Starbase Electrolyser series has a superior capacity therefore it is Ideal for large-scale projects.



  • Large-scale systems

  • 10 – 100+ MW

  • Based on a 10 MW stack

  • Skid-mounted modular units
