Hydrogenious LOHC Technologies, the German pioneer in the field of liquid organic hydrogen carriers (LOHC), has signed a contract with the Griesemann Gruppe for the Front-End Engineering and Design (FEED) phase and the subsequent EPCM phase (Engineering, Procurement and Construction Management) for its Green Hydrogen @ Blue Danube project.
The scope of work includes engineering, procurement and construction services for what will become the world’s largest LOHC release plant at the Bayernoil refinery in Vohburg, with a release capacity of up to five tonnes of RFNBO-certified hydrogen per day.
Equivalent to around 1,800 tonnes of green hydrogen per year, this output could replace grey hydrogen produced from natural gas and save up to 16,000 tonnes of CO₂ annually.
A potential expansion of the dehydrogenation plant could further contribute to a secure hydrogen supply and the future decarbonisation of industries across the Danube region.
The FEED phase is scheduled for completion in the second half of 2026, representing an important milestone on the path to reaching FID (Final Investment Decision) for the Green Hydrogen @ Blue Danube project.
Following a positive FID, on-site construction will begin, with the start of commercial operations planned for mid-2028.
The first LOHC supply chain will secure hydrogen availability in Bavaria. Hydrogenious’ “Hector” project, currently under development, demonstrates the large-scale storage of RFNBO-certified hydrogen in LOHC at a storage plant located at Chempark Dormagen, North Rhine-Westphalia. The Green Hydrogen @ Blue Danube project will establish the corresponding release plant on the offtaker side.
