- Development of sustainable storage solutions for green hydrogen on a commercial scale
- EPCm contract for Bilfinger follows convincing engineering performance
- Bilfinger’s demonstration plant “H2DRY” enables efficient, large-scale hydrogen treatment
Krummhörn, Germany. Bilfinger has been commissioned by energy company Uniper to provide engineering, procurement and construction management (EPCm) services for a pioneering hydrogen project in the Krummhörn cavern storage facility. The aim of this research project is to develop a commercial storage solution for green hydrogen on a large scale. Uniper’s storage facility will be one of the first of its kind and is the second research project to use the hydrogen processing technology “H2DRY” developed by Bilfinger.
Uniper plans to construct a hydrogen storage facility with a capacity of up to 3,000 m3 in a pilot cavern in the former Krummhörn natural gas storage facility and operate it under real conditions. The knowledge gained during the two-year test phase will form the basis for larger-scale projects and the construction of commercial hydrogen caverns.
A team from the Bilfinger Engineering & Maintenance GmbH unit will provide engineering, procurement and construction management services for the planned construction of above-ground hydrogen processing facilities.
In addition, Bilfinger is coordinating the delivery and installation of a hydrogen drying system at the site, which was developed by the industrial services provider. The so-called “H2DRY” technology uses a suitable scrubbing liquid to remove water from the hydrogen by absorption, which is created during production in electrolysers or in contact with moisture in the cavern. The technology enables economical and efficient hydrogen treatment on a large scale and is based on Bilfinger’s many years of experience in the field of gas storage.
