The scope of work covers engineering, procurement, and construction management for a Liquid Organic Hydrogen Carrier (LOHC) release plant to be built at the Bayernoil refinery in Vohburg, Bavaria. The facility will have a release capacity of up to five tonnes of RFNBO-certified hydrogen per day – equivalent to around 1,800 tonnes per year – replacing grey hydrogen from natural gas and reducing CO₂ emissions by up to 16,000 tonnes annually.
Completion of the FEED phase is scheduled for the second half of 2026, marking a major milestone on the path to a final investment decision (FID) for Green Hydrogen @ Blue Danube. Subject to a positive FID, construction will begin thereafter, with commercial operations planned for mid-2028.
Together with Hydrogenious’ Hector project – which demonstrates large-scale hydrogen storage in LOHC at Chempark Dormagen, North Rhine-Westphalia – the Green Hydrogen @ Blue Danube project will form the release counterpart of the company’s first end-to-end LOHC value chain. The combined LOHC Link initiative will enable the storage, transport, and release of RFNBO hydrogen for industrial offtakers in Bavaria and the wider Danube region.
The plant will be based on Hydrogenious’ proprietary LOHC technology, which uses the thermal oil benzyl toluene (LOHC-BT) as a carrier medium to store hydrogen safely and efficiently under ambient conditions. The hydrogen-loaded carrier can be transported using existing infrastructure for conventional liquid fuels.
Dr Stefan Bürkle, Chief Operating Officer at Hydrogenious LOHC Technologies, said: “Launching the FEED phase is an important step in scaling up our LOHC technology to the industrial level. The storage and release plants together will demonstrate how hydrogen can be stored, transported, and supplied safely and efficiently to decarbonise industry and strengthen hydrogen supply security.”
Uwe Gaudig, Managing Director at Griesemann Gruppe, added: “Hydrogenious’ LOHC technology provides an important foundation for the availability of green hydrogen. We are pleased to contribute our engineering expertise to this pioneering project, supporting the safe and efficient transport of hydrogen as part of the energy transition.”
