Hydrogenious LOHC Technologies, German provider of liquid organic hydrogen carriers (LOHC), has signed a contract with the Griesemann Gruppe for the front-end engineering and design (FEED) and the subsequent engineering, procurement and construction management (EPCM) phase for its ‘Green Hydrogen @ Blue Danube’ project.
The scope of work includes engineering, procurement and construction services for the world’s largest LOHC release plant at the Bayernoil refinery in Vohburg, Germany, with a release capacity of up to 5 tpd of RFNBO-certified hydrogen from LOHC.
Corresponding to 1800 tpy of green hydrogen, this can replace grey hydrogen produced from natural gas and thus save up to 16 000 tpy of CO2. A potential expansion of the dehydrogenation plant could further contribute to a secure hydrogen supply and future decarbonisation of industries in the Danube region.
The FEED phase is planned to be completed in the second half of 2026 which will represent an important milestone to reach final investment decision (FID) of the ‘Green Hydrogen @ Blue Danube’ project. Following a positive FID, the construction phase will begin on site. Start of commercial operations is planned for mid-2028. First LOHC supply chain will secure hydrogen availability in Bavaria.
Hydrogenious' project ‘Hector’ demonstrates the large scale storage of RFNBO-certified hydrogen in LOHC with a storage plant at Chempark Dormagen, North Rhine-Westphalia. The ‘Green Hydrogen @ Blue Danube’ project will establish a corresponding release plant on the offtaker side.
Combined, the two projects form the ‘LOHC Link’ – a comprehensive and sustainable hydrogen value chain including storage in LOHC, safe transport, and the release and supply of RFNBO hydrogen to industrial offtakers.
Project of common European interest
The ‘Green Hydrogen @ Blue Danube’ project has been notified as an ‘Important Project of Common European Interest’ (IPCEI) by the European Commission and receives funding from the German Federal Government and the Bavarian State Government.
The plant will be operated based on Hydrogenious' innovative Liquid Organic Hydrogen Carrier (LOHC) technology, which uses the thermal oil benzyl toluene (LOHC-BT) as a carrier material to store hydrogen safely, efficiently, and flexibly. The LOHC-BT can be transported by deploying already established infrastructure for conventional mineral oil products. As part of the ‘LOHC Link’ supply chain, hydrogen-loaded BT will be transported by truck at ambient conditions.
Competent and experienced partner for FEED and EPCM
Following a tender process, Hydrogenious selected the Griesemann Gruppe as its engineering partner for the FEED phase, with the aim of developing the project to FID. Given the Griesemann Gruppe's project execution capabilities for complex process plants, Hydrogenious intends to entrust the Griesemann Gruppe with the EPCM services of the world’s first industrial scale LOHC release plant.
Dr Stefan Bürkle, Chief Operating Officer of Hydrogenious LOHC, commented: “Launching the FEED phase, is a strong sign of scaling-up our LOHC technology to an industrial level – and will kick-start the implementation of the first commercial LOHC value chain of a material size. The storage and release plants combined will demonstrate how hydrogen can be stored, transported, and supplied safely and efficiently – decarbonising industries and ensuring security of hydrogen supply.”
Dr Andreas Lehmann, Chief Executive Officer at Hydrogenious LOHC, added: “At a time when the hydrogen economy is facing uncertainties, we need tangible projects and technology-neutral approaches. The FEED phase for 'Green Hydrogen @ Blue Danube' is not only a technical milestone – it is a signal to policymakers and industry to stay on track and actively shape the ramp-up of the hydrogen economy based on innovative solutions such as LOHC.”
Uwe Gaudig, Managing Director of Griesemann Gruppe, stated: “Hydrogenious' LOHC technology creates the essential conditions for the scaling and availability of green hydrogen. The Griesemann Gruppe is delighted to be part of bringing this innovative technology to fruition, in collaboration with our partner. Drawing on our experience as an engineering partner and EPC contractor, we are committed to contributing to the energy transition and transformation of industry. Ensuring safe and efficient transport is a vital step in the hydrogen value chain.”
