EWE is developing a large-scale green hydrogen production facility at its Emden site, with an installed electrolyzer capacity of 320 MW. The project requires extensive auxiliary and peripheral equipment to prepare the hydrogen for industrial use, including dedicated gas purification systems.
Under the contract, ReiCat will supply hydrogen purification units that form part of the electrolyzer’s technical peripheral systems. The purification technology ensures that the electrolytically produced hydrogen reaches a purity level of more than 99.999%, meeting the quality requirements for downstream applications.
The Emden hydrogen plant represents the central element of the multi-part ‘Clean Hydrogen Coastline’ flagship project. The initiative integrates hydrogen production with storage, transport, and utilization. With its planned capacity, the facility is expected to rank among the largest hydrogen production plants of its kind in Europe.
The purified hydrogen will be supplied to industrial customers and the mobility sector. According to the project description, the facility is also intended to contribute to the long-term resilience of the regional energy supply system in northern Germany.
“For the industrial use of green hydrogen, consistently high gas quality is essential. With ReiCat’s purification systems, we are relying on proven technology in Emden that perfectly complements our electrolysis operations. This collaboration is a key element for the reliable and safe operation of our large-scale hydrogen production,” said Tobias Moldenhauer, Managing Director of EWE HYDROGEN GmbH.
Michael Höfling, CEO of ReiCat, added: “We are delighted to be working with EWE and proud to contribute to this European lighthouse project with our ‘Made in Germany’ hydrogen purification systems. As a technology partner, we bring more than 40 years of experience in hydrogen treatment and purification.”
