PEM electrolysis stacks for your electrolyzer

hyworx Electrolyzer Stacks -
the core component for generating green hydrogen

hyworx Electrolyzer Stacks
Many markets, two sizes

To drive forward the energy transition, hyworx is focusing on the development of two sizes of PEM electrolysis stacks as core components for electrolysers:

(1) For local, decentralized hydrogen production:
hyworx Electrolyzer Stacks of the S Series

(2) For integration into large industrial plants in the multi-megawatt range:
hyworx Electrolyzer Stacks of the XL Series

hyworx Electrolyzer Stacks of the S Series

4 - 40 kW

Efficient stacks for local, decentralized hydrogen production

hyworx PEM electrolysis stacks from the S Series are designed to ensure the self-sufficient production of green hydrogen to cover internal demand as a process gas or for energy supply. This is the perfect solution for companies that want to become independent of central suppliers.

hyworx PEM electrolysis stacks of the S series

  • Rated stack power: 4 - 40 kW*

    (depending on the number of cells installed)

  • SOP (start of production): Q3/26*

* As of October 2025

Independence
from natural gas

Replace natural gas consumption with your own hydrogen. PV systems can be coupled with electrolysers to end dependence on fossil fuels.

Saving costs in hydrogen supply

Replacement of H2 rental cylinders in manufacturing. With an electrolyzer, companies can produce their own hydrogen and reduce their operating costs.

Efficient
energy storage

An electrolyzer combined with a storage unit and a fuel cell is a powerful alternative to battery storage systems.

Ideal for
training

Our technology is ideal for universities and vocational schools for practical teaching on the hydrogen economy and the energy transition.

We are working on expanding the S-Stack to up to 100 kW  in order to serve the aforementioned markets even more comprehensively.

hyworx Electrolyzer Stacks of the XL Series

2.0 MW

High-performance stacks for large industrial plants in the multi-megawatt range

The PEM electrolysis stacks in the XL Series from hyworx are designed for the megawatt range, ideal for the centralized production of green hydrogen in large industrial plants and for energy storage.

hyworx XL Series PEM Electrolysis Stacks

  • Rated stack power: 2.0 MW
  • SOP (start of production): Q3/27*

* If financing is successful by mid-2026
As of October 2025
