Efficient solution for
the industrial drying of hydrogen


Leibniz Universität Hannover, EWE GASSPEICHER GmbH und Uniper Energy Storage GmbH




Bilfinger is building a demonstration plant for the drying of green hydroge.


As part of the research project sponsored by the German state of Lower Saxony, Bilfinger is designing and building a hydrogen drying plant. The plant will pave the way for a new process that dries hydrogen by absorbing moisture with a suitable scrubbing liquid. This will allow large quantities of green hydrogen to be dried efficiently and cost-effectively for pipeline transport. The technology will have applications in areas including large-scale hydrogen production plants and so-called caverns, where hydrogen is stored on a long-term basis in deep layers of the earth.

The plant is located on the first test field. First tests will be completed by the end of 2023.

added value:
  • Bilfinger's many years of experience in natural gas drying have resulted in an efficient and proven solution for large-scale hydrogen drying

  • Expertise in the integrated hydrogen value chain

  • Bilfinger is making a key contribution to reducing dependence on natural gas
