One team,

one goal: 100% green energy.

Behind hyworx are experts
with a genuine passion for hydrogen.

We are a specialized team dedicated to developing innovative hydrogen technology. Our focus is on designing PEM electrolysis stacks that use renewable energy to split water into oxygen and green hydrogen.

Led by Stefan Höller, we combine a strong technical foundation with a solution-oriented approach. Small enough to offer maximum flexibility, yet experienced enough to deliver cutting-edge technological solutions.

Let’s shape the energy transition together. We look forward to hearing from you and to working with you as equal partners.
