%X We demonstrate that the combination of hydrogen release from a Liquid Organic HydrogenCarrier (LOHC) system with electrochemical hydrogen compression (EHC) provides threedecisive advantages over the state-of-the-art hydrogen provision from such storage system:a) The EHC device produces reduced hydrogen pressure on its suction side connectedto the LOHC dehydrogenation unit, thus shifting the thermodynamic equilibrium towardsdehydrogenation and accelerating the hydrogen release; b) the EHC device compresses thehydrogen released from the carrier system thus producing high value compressedhydrogen; c) the EHC process is selective for proton transport and thus the process purifieshydrogen from impurities, such as traces of methane. We demonstrate this combinationfor the production of compressed hydrogen (absolute pressure of 6 bar) from perhydrodibenzyltoluene at dehydrogenation temperatures down to 240 C in a quality suitable forfuel cell operation, e.g. in a fuel cell vehicle. The presented technology may be highlyattractive for providing compressed hydrogen at future hydrogen filling stations thatreceive and store hydrogen in a LOHC-bound manner.
