In the recent advances towards more sustainable global energy supply, H 2 is a possible alternative for large scale energy storage. In this view, Liquid Organic Hydrogen Carriers (LOHC) are a class of molecules that allow for easier long term energy storage compared to conventional H 2 technologies. CFD simulations were used to showcase the hydrodynamics of the dehydrogenation of a LOHC in a new reactor unit, via a cold flow mock-up study. This reactor was designed to allow for a swirling motion of the liquid carrier material, favouring the removal of H 2 gas from the flow and forcing the equilibrium of the reaction towards dehydrogenation, as well as to keep the catalyst particles in motion. The CFD simulations were validated qualitatively with experimental operation of the reactor, in a system with identical dimensionless numbers (Reynolds and Stokes), in order to use less costly products during the prototyping phase. • A new swirling reactor is introduced for H 2 release of perhydro dibenzyltoluene. • The cold flow mock-up study shows fluidization of the catalyst beads. • Presence of the gas phase is crucial in fluidization of the catalyst bed. • A method for simulating three phase flows with open-source software is presented.
