Evonik has signed an agreement to develop, scale up and produce proprietary fixed bed catalysts for mobile applications of Hydrogenious LOHC Technologies’ proprietary liquid organic H₂ carrier (LOHC) technology based on benzyl toluene (BT).

The safe, cost-efficient and flexible process chemically binds H₂ synthesized by sustainable energy to the LOHC-BT, which then is transported to the offtaker site where the H₂ is released for industrial or consumer use, or in the mobile application released on board to power propulsion units.

“We are committed to bringing our expertise in catalysis to jointly develop processes with the Hydrogenious team, that will help to transform the industry from fossil-based to sustainable feedstock,” said Michael Frey, Head of Product Line Polyolefin and Continuous Process Catalysts, at Evonik.  

“When transporting H₂ over long distances, liquid organic carriers play a particularly important role. To overcome catalytical challenges associated with the use of onboard applications, customization—based on extensive and proven experience—is required,” he added.

Hydrogenious’ LOHC process uses benzyl toluene as carrier material, boasting competitive safety and economic advantages. The thermal oil—which is loaded with H₂—is hardly flammable and non-explosive, with a risk potential comparable to diesel fuel. It can be stored at ambient temperatures and pressure, has a competitive storage density level, and is reusable as a H₂ carrier hundreds of times.

"The flexibility and scalability of our LOHC technology accelerates the ramp-up of the H₂ economy because we can leverage the existing liquid fuel infrastructure," said Dr Caspar Paetz, Chief Technology Officer (CTO) of Hydrogenious LOHC Technologies.

"We are happy to work with Evonik to further improve our technology - their expertise in tailoring catalysts to specific needs is an essential part of the development process," he added.

Catalysts for pilot plants and commercial units are expected to be available from 2026 onwards.
