Four arguments for a robust system:
the zinc intermediate step electrolysis.
Cost-effective green hydrogen
Our system uses renewable energy from e.g. solar and wind power in phases of high energy production. The power to run the STOFF2 Zinc Zwischenschritt Electrolyzer can therefore be purchased cost-effectively to reduce the cost of hydrogen produced.
Energy storage and electrolysis
Thanks to the hybrid functionality of the zinc intermediate step electrolysis with inherent energy storage function, our system is already today RED II-compliant, less technically complex and can be integrated more easily into the existing electricity and gas supply.
Hydrogen at the push of a button
The Zinc Zwischenschritt Electrolyzer separates timing of power intake and hydrogen production. This makes it possible to produce hydrogen on demand and also to use otherwise curtailed renewable energies.
Resource-efficient and safe
Our technology does not need PFAS, platinum, cobalt or lithium, but zinc, which is widely available and can be produced cheaply. The energy is not stored in gaseous form, but as a solid metal which conserves resources and is safe.
A technology that puts
1 and 1 together.
In the first step, electricity is drawn at high power and the energy it contains is stored in the system. Oxygen is released in the process and metal is deposited on an electrode.
Energy that is safe and constant.
The energy is safely stored in the form of solid zinc; this is what we call the zinc intermediate step or in german “Zwischenschritt”. Our system does not store the energy in gaseous form, which means additional safety.
Hydrogen that delivers reliably.
When discharging, the energy stored in the zinc layer is released as hydrogen: the zinc dissolves into the electrolyte and hydrogen is produced at the gas electrode. In addition, electricity and heat are generated. Since the charge-storage-discharge cycle is asynchronous, it can be flexibly adapted to special requirements.
We enable the
green hydrogen value chain.
