Future called, said it’s great.

STOFF2 makes hydrogen:
Secure, cost-effective, green!


A technology that finally puts 2 and 2 together.

We have developed an electrolyzer with a new innovative technology: the Zinc-Intermediate Electrolyzer. This hydrogen generating technology is flexible and has an integrated energy storage function. It offers the combined functions of a battery and an electrolyzer. As a result, it is ideally suited to produce hydrogen from volatile renewable electricity in a cost-effective and CO2-neutral manner.


Our system captures the cheapest electricity in times of abundant renewable energy. We provide CO2-free generated hydrogen to our customers as needed by converting volatile sources into a steady supply.


Our key advantages:

  • Electrolyzer with integrated storage function
  • Fast charging and continuous hydrogen production
  • Reliable renewable electricity as an additional product
  • High efficiency

‘Stoff geben’ – Accelerating decarbonization by enabling green hydrogen.

The EU has committed to become climate neutral by 2050 and reduce CO2 emissions by at least 55% by 2030. We do not know which paths the individual states will take, but one thing is certain: Green hydrogen will play a crucial role in making fossil and nuclear energy obsolete.
