Hydrogen-resistant control valves for innovative HyCARE storage system

About the HyCARE project

The storage of renewable energy is still a major challenge. The HyCARE project has set itself the task of using hydrogen to store energy from renewable sources such as photovoltaics and wind. This project is unique in Europe: The developed, innovative plant technology stores 50 kg of hydrogen in large hydrogen tanks using metal hydrides at low pressure and low temperature.

The goal is to install a thermal management system that increases the overall efficiency of such plants and stores renewable energy sustainably and permanently - for later use as needed.

The requirement: Safe control of hydrogen

For the supply line to the HyCARE storage system, Stühff needed two valves that could withstand the high demands of hydrogen, a critical medium. The gas can easily penetrate a wide variety of materials and lead to embrittlement. To prevent this, the control valves must be of special and high-quality material.  

In order to control the smallest flow rates of hydrogen, our low-flow set was used here.

The result: H2-Ready control valves from A. Hock

The innovative showcase project HyCARE has received a lot of international attention. A. Hock delivered the hydrogen valves, specially adapted to the novel plant and the critical medium, within a very short time.
