As the main sources of renewable energy are affected by intrinsic stochastic availability, the sustainability of electrified mobility hangs substantially on the energy supply. A constant renewable energy supply is dependent on an appropriate application of energy storage technologies, avoiding the appearance of the so called 'winter hole' . This term refers to the shortage of electricity that can appear in countries where the energy supply is solely based on seasonal-subject resources. The historically available energy storage methods, such as batteries, pumped storage hydroelectricity and flywheels have limited capacity on the time scale and would require excessive space and investment to be extensively used on the seasonal scale . For this reason, the seasonal storage of electricity in chemical bonds has raised as a promising option over the last few years . In this context, production of H2 by water electrolysis is regarded as the most mature technology to produce an energy vector from electricity . However, direct H2 storage presents various challenges, due to the low volumetric energy density of gaseous H2 and to the low boiling point. Hence, for practical applications, H2 should better be converted to chemical molecules that carry H2 in solid (e.g. metal hydrides ) or in liquid form (e.g. liquid organic carriers ).
