Hydrogen a key component of the energy transition

Prometheus, the innovative series of PEM electrolysis stacks, is the result of more than 25 years of expertise and pioneering work by Stefan Höller, founder, Managing Director and Head of Development of Hoeller Electrolyzer.

The German start-up has one clear goal: green hydrogen for less than €4 per kilogram.
