In the last two centuries the continuous emissions of CO2 level has brough the greenhouse effect at unimaginable levels, due to an uncontrollable use of fossil fuels. The objective to stay within the 2 °C increase within 2050 is challenging but the continuous development of renewables is year by year most promising. Their intermittency makes them unreliable without proper energy management strategies and efficient storage systems, so far, the use of modern batteries is crucial to store surplus energy from renewables and new storage technologies are in development. Among them the use of hydrogen as storage has draw the attention of plenty of researcher.
