10. Outlook

Dihydrogen is a highly investigated area of applied research. Clearly, particular care must be taken to control the entire value chain, from source to use. Particular attention needs to be paid to the risks of leaks, accidents and active safety, as well as to the fuelling and storage of this energy.

The 5 priority paths to be favored to decarbonize mobilities with a diversified energy mix concern electricity, hydrogen, enriched hydrogen, gaseous fuels such as biomethanization and its derivatives with biomass, synthetic fuels obtained by combining hydrogen with CO ₂ .
