Up to 80 percent efficiency

Up to 80 percent efficiency

In the water electrolysis process, electricity is passed through water and breaks it down into oxygen and hydrogen. Excess electricity can be used for this and converted into a different energy source – hydrogen. This is useful when additional energy is needed. Then, the hydrogen can be turned into electricity again.

The technology is well-known but we aim to make it more cost-effective. The chances are good that our process will reduce the capital costs of water electrolysis plants by a factor of 3.5 to 5. We are also targeting efficiency of up to 80 percent.

Water electrolysis: Power to gas

We are reducing costs and increasing efficiency


In this we benefit from our experience with chlor-alkali electrolysis, a technology similar to water electrolysis for which we have already sold more than 100,000 elements.

An initial lab-scale plant has already been built. The next planned step in the development process is a pilot plant.

Successes:

  • Up to 80 percent efficiency
  • Investment costs 3.5 times lower
