The HySTOC project has the primary objective to demonstrate the feasibility of the Liquid Organic Hydrogen Carrier (LOHC) technology for distribution and storage of hydrogen to supply Hydrogen Refuelling Stations (HRS).
Hydrogen is the most tangible path towards providing a renewable fuel that combines easy and quick refuelling with long ranges even for large cars, trucks and busses. Therefore, hydrogen is a versatile energy carrier that will allow the EU to accomplish its strategic targets of zero-emission mobility, integration of renewables and the decarbonisation of industry.
Although hydrogen is currently nearly exclusively produced from natural gas, it can be produced renewably by splitting water via electrolysis, making it abundantly available. However, its low density and explosive nature make hydrogen storage and transport technically challenging, inefficient and comparably expensive.
The LOHC-technology provides several advantages to overcome these issues and therefore to support hydrogen mobility targets within Horizon 2020.
High transport capacity
Up to 5x higher transport capacity per 40-to truck compared to 200 bar tube trailers and up to 3x higher compared to 500 bar tube trailers
Low transport cost
LOHC reduces operating costs of hydrogen logistics by up to 80%. Potential use of standard oil tank infrastructure reduces investment costs significantly
Easy road transport
The LOHC of choice in the HySTOC project is dibenzyltoluene (DBT), which is classified as a non-hazardous good according to ADR. Handling of hydrogen bound to LOHC can be done at ambient conditions.
As the hydrogen is chemically bound, no molecular hydrogen has to be stored. The carrier material (DBT) is hardly flammable and non-explosive, allowing storage of large amounts of hydrogen at existing refuelling stations
