About our technology

Thanks to a great amount of scalability and flexibility, we can offer a decentralized turnkey hydrogen solution for every situation.

Turnkey electrolyzers housed in a single container

Our complete PEM-system is housed in a single, custom built container. This approach ensures that every decentralized turnkey hydrogen solution we offer is easy to ship and ready to go.

Keep meeting rising energy demands with major benefits – onsite generation, storage and distribution with zero emissions.​ With our turnkey PEM-system housed in a customized container, it’s ready to be delivered to any location without much hassle. Easy installation and integration is guaranteed, since all it requires onsite is to be connected to a power and a water source.

Container sizes may vary, depending on hydrogen requirements and their corresponding system size.​ Please check the technical specifications further down this page for more info on any of our different solutions and models.

How we turn PEM technology​ into a decentralized turnkey hydrogen solution

proton exchange membrane

Inside each electrolyzer container are Proton Exchange Membrane stacks, designed to generate hydrogen gas:

  • Proton Exchange Membrane (PEM) technology splits water into H2 and O2
  • The PEM device allows for separate storage of H2 and O2
  • The generated hydrogen can be stored for later use in a fuel cell

The PEM system requires two inputs: power and water. The semipermeable membrane inside is an ion conducting material, allowing only the hydrogen ions (H+) to pass through. With input power, the water molecules are split at the membrane interface, resulting in a current through the system and an oxygen exhaust. The H+ ions pass through the membrane and recombine with the electrons to form H2 molecules, and thus hydrogen fuel.
