Construction and operation of world’s largest project plant for storing green hydrogen kicks-off


Germany – The world’s largest plant for storing green hydrogen in liquid organic hydrogen carriers (LOHC) on an industrial scale is being built at CHEMPARK Dormagen.

The State of North Rhine-Westphalia is financing the initiative with a funding of €9 million from the programme. The Krefeld-based subsidiary of Hydrogenious LOHC Technologies, LOHC Industrial Solutions NRW GmbH, will be responsible for project management and plant operation. The Erlangen-based parent company, with its patented LOHC technology, will contribute the main element and the corresponding scaled plant method. The site area and, in the future, the green hydrogen will be supplied by its investor Covestro Deutschland AG.

Possible extension

The technical partner is the Jülich Research Center with its Institute for Energy and Environment Research. €2 million in support for accompanying research experiments will go there. A possible extension of the project and the potential development of a green hydrogen supply chain between the plant in Dormagen and Rotterdam is also expected, along with the Dutch co-investor Royal Vopak. Green hydrogen would be emitted from LOHC and would be used mainly in the mobility and manufacturing industries.

One of the goals of the project is to incorporate the heat energy emitted during the LOHC hydrogenation process into the steam network and thereby into the site’s energy supply. As a result, the total performance of the LOHC cycle can be greatly improved. The plant is expected to be completed in 2023. Covestro Deutschland AG – a shareholder of Hydrogenious LOHC Technologies since mid-2019 – aims to supply green hydrogen for this purpose. In the future, this will be developed at the site as an agricultural by-product.
