In the past decades the emissions of greenhouse gasses contributed to the global warming, a product of the emission of the fossil fuels. To solve this problem the governments agreed to implement the renewable energy production, exploiting resources such as solar, wind, geothermal and ocean. These resources could reduce the greenhouse gasses emissions playing a main role in the goal to reach the carbon neutrality by the 2050. These types of energy come out of the nature and so is not possible to plan the production and modelling it as required by the energy demand. The only way the production can meet the demand is through energy storage or energy carriers, like hydrogen.
