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 supporting the project with funding of €9 million. The Krefeld-based subsidiary of Hydrogenious LOHC Technologies, LOHC Industrial Solutions NRW, will take charge of project management and plant operation.
Its investor Covestro Deutschland will provide the site area and, in the future, the green hydrogen. The scientific partner is the Jülich Research Centre with its Institute for Energy and Climate Research. Two million euros of the funding for accompanying scientific studies will go there. Together with the Dutch co-investor Royal Vopak, a possible expansion of the project and potential establishment of a green hydrogen supply chain between the plant in Dormagen and Rotterdam is also being planned. There, the green hydrogen would be released from the LOHC and used primarily in the mobility and industrial sectors.
“As part of our project, we are making the Dormagen CHEMPARK the home of the world’s largest pilot plant for storing green hydrogen in LOHC – we will use our proprietary technology based on the LOHC carrier medium Benzyltoluene for this purpose. With the planned plant capacity, about 1,800 tonnes of hydrogen per year can be stored in LOHC.“Daniel Teichmann, founder and CEO of Hydrogenious LOHC Technologies.
One focus of the project is to integrate the heat energy released during the LOHC hydrogenation process into the steam network and thus into the site’s energy supply. The overall efficiency of the LOHC cycle can thus be significantly increased.
Commissioning of the plant is scheduled for 2023. Covestro Deutschland, a shareholder in Hydrogenious LOHC Technologies, plans to supply the green hydrogen for this purpose. This will be produced at the site in future as an industrial by-product.
