Hydrogen was at the heart of the debate at COP 21 held in Paris in December 2015. Hydrogen will play an important role in the energy transition in addition to renewable energy.
Renewables are intermittent and may produce more energy by the time that the network can absorb or even does not produce enough energy to meet network demands.
This phenomenon is observed with photovoltaic solar panels that produce an energy surplus between 10h and 16h but do not cover a home’s needs in the morning or in the evening.
Hydrogen allows, in particular, to store a surplus of energy compared to intermittent energies as it overcomes the constraints of decentralized production and finally its use can significantly reduce emissions of greenhouse gases.
Hydrogen thus has a relevant role in the energy transition, though its industrial operation still requires a lot of investment.
