LOHC, a Compelling Hydrogen Transport and Storage Solution

Industrialized and high energy demand regions may lack the potential to produce renewable energy required for producing sufficient quantities of Low Carbon Hydrogen at competitive cost. Thus, importing Hydrogen may be necessary after maximizing their own renewable energy production.

Hydrogen is becoming an essential vector of the global energy mix as we move towards renewable energy and decarbonization. However, the transportation and storage of Hydrogen pose logistical and safety challenges. Liquid Organic Hydrogen Carriers (LOHC) offer a compelling solution for establishing a cleaner and more sustainable Hydrogen supply chain.

LOHC Schemes

How Liquid Organic Hydrogen Carrier (LOHC) works?

The family of carrier selected is Toluene (“TL”) and MethylCycloHexane (“MCH”). These carriers are preferred due to their low toxicity, chemical stability, and ease of handling and storage. They can be stored in existing oil infrastructures at ambient conditions without losses during transport or storage, offering significant advantages over other options. 

The concept is binding H2 to TL. This step is called hydrogenation and is performed at the location where H2 is produced. Then liquid MCH is easily and safely stored and transported to importing regions. At this location, chemical binding is broken to release H2 and TL. This step is called dehydrogenation. TL is then returned to the producing country to complete the cycle. 

To propose the complete LOHC chain, Axens allied in 2022 with Chiyoda Corporation, each Company offering TL Hydrogenation and SPERA MCH DeHydrogenation respectively.
