The Green House Gas emissions in the atmosphere and the corresponding rise of temperatures represent an ongoing global issue. Knowing that the main emitting sources are in the energy sector is pushing countries all over the world towards a diffusion of the renewable energy sources (e.g. solar, wind) to cover an increasing energy need. In this direction, some challenges arise in terms of efficient utilization of the surpluses and deficits, distributed resources, reliability and integration for the grid stability. Energy storing system could be required to deal with intermittent operations of this energy source. To address such challenge, hydrogen can be considered a good alternative candidate.
