Liquid Organic Hydrogen Carriers (LOHC) is the term used for a substance that can be used to hold hydrogen without any off gassing. We use the thermal oil Benzyl Toluene (BT-V) with the commercial name Marlotherm LH as our carrier material. The unique properties of our LOHC carrier material enables us to bind hydrogen in the oil through an exothermic reaction. The process requires a reactor, catalyst material and 15-30 bar pressure. After the hydrogen is bound in the oil, we get perhydro-benzyl toluene (BT-H) that has the capacity to carry 54kg H₂/m³ or 62kg H₂/t. BT-H can now be stored or transported at ambient pressure and temperature with the use of conventional equipment used for MGO or Heavy Fuel. This enables us to re-use infrastructures that today are used for carbon based fuel and thus there is now need to invest in building new infrastructure to realise LOHC as a fuel.

On board the ship we make the hydrogen available again with our LOHC release unit. The process on-board is an endothermic reaction with the use of a reactor, catalyst material and heat to release hydrogen from the LOHC oil and feed it to a hydrogen off taker i.e. Fuel cell or internal combustion H₂ engine.
