German cleantech company Hydrogenious LOHC Technologies has begun supplying hydrogen to a vehicle filling station in Erlangen, Germany, using its proprietary liquid organic hydrogen carrier (LOHC) technology.
The use of Hydrogenious’ LOHC marks the implementation off the full LOHC supply chain. The new filling station, at Henri-Dunant-Strasse 2 in Erlangen has been built and is operated by H2 MOBILITY Germany. Up to now, such filling stations have been supplied solely with compressed hydrogen, but this limits storage capacities and requires a lot of space. LOHC, according to Hydrogenious, offers a viable alternative, with safe, simple handling. The LOHC is based on benzyltoluene, which is flame-retardant and non-explosive, and can be stored in conventional underground tanks as for other liquid hydrocarbons.
The new filling station offers hydrogen at two pressure levels – 350 bar for buses and commercial vehicles and 700 bar for hydrogen cars. Hydrogen is released from the LOHC onsite using the ReleaseBox10, housed in a 30’ (9 m) container. Release occurs at 45 bar, before the hydrogen enters an intermediate storage tank where it is compressed to the correct pressure. LOHC is transported to site using a conventional tanker.
The filling station demonstration is part of Hydrogenious’ H2Sektor pilot project, which has received subsidies from the Bavarian State Ministry for Economic Affairs and Energy. With H2Sektor, Hydrogenious intends to develop and research a complete LOHC-based chain from green hydrogen production, to transport, and the use of hydrogen for mobility.
‘With our LOHC-based solution, hydrogen refuelling stations can be supplied with hydrogen easily, safely and in an area-optimised manner, especially in densely populated, urban areas. With the H2Sektor project, we are laying the foundation for large-scale hydrogen refuelling stations, which are needed especially for commercial vehicles and the operators of large hydrogen-based truck and bus fleets, thus supporting the decarbonisation of the mobility sector. From the operation of the very first LOHC-supplied refuelling station, we will gain valuable practical knowledge for the production, transport and supply of green hydrogen for mobility applications. Together with other hydrogen offtakers from industry and transport, the Erlangen filling station will become part of our transregional supply chain for green hydrogen, which we are developing with European partners, for example, as part of the Important Projects of Common European Interest,’ says Dr Daniel Teichmann, CEO and founder of Hydrogenious LOHC Technologies.
Hydrogenious recently announced the successful conclusion of the HySTOC EU project to test an efficient hydrogen value chain utilising its LOHC technology in Finland, from production to use. In March 2022, the company signed a joint study agreement with Uniper, JERA Americas and Abu Dhabi National Oil Company (ADNOC) to explore hydrogen transportation between the UAE and Germany using its LOHC technology.
