Green energy – hydrogen storage solutions for the energy transition

Goodbye complexity, hello clarity – with VAKO’s experience.

Many green energy projects start with unanswered questions and uncertainties surrounding hydrogen and its storage: Which storage solution is the right one? What pressure and volume should be used? Which standards must be observed? What are the costs involved?

VAKO offers clear guidance here. We develop solutions for the storage of hydrogen that are safe, tested, and economical—and accompany you as an experienced partner from planning and production to commissioning.

Future-proof projects:

Wilo H₂Powerplant x VAKO

State-of-the-Art Hydrogen Plant

The H2Powerplant in Dortmund is one of the world’s most advanced hydrogen plants – a pilot project that combines renewable energy, storage, and reconversion. We are very proud that our storage solutions help to ensure that surplus solar and wind energy can be stored efficiently and converted back into electricity when needed. 

With its modular design, high safety standards, and comprehensive integration, this plant has proven its worth many times over in practice. Innovative storage solutions like this enable green energy to be used locally and autonomously – our technology in a groundbreaking application.
