STOFF2 uses its innovative technology to convert solar and wind power into green hydrogen and green electricity. Stoff2 has developed the so-called Zinc Intermediate Electrolysis (ZZE) for this purpose. The ZZE combines energy storage and electrolysis in one device. This makes it possible to generate a constant green hydrogen output from fluctuating renewable energies using the storage concept. Whether for green industries, for CO2-free mobility, for sustainable chemistry or for the municipal utilities of the future – the hydrogen produced in this way can be made available to customers as required.
