11.1 Scope

It is widely known that “without a technological shift, the EU will fail on its 2050 ambitions” [1]. In this context, hydrogen‐based energy has the potential to play a major role in decarbonizing the European energy landscape in the coming decades. Hydrogen provides a clean alternative energy carrier that can be easily produced from several kinds of primary energy sources, stored, and distributed. Its relevance is transverse to the entire energy sector, such as transportation, buildings, utilities, and industry. Through combination with fuel cells, power can be generated in the desired quantities and with no additional greenhouse gas emissions.

Hydrogen can be produced using an extensive range of fuels (e.g. natural gas and coal, biomass, non‐food crops, nuclear energy) [2] and renewable energy (e.g. wind, solar, geothermal, and hydroelectric power) [3] through advanced technologies, in centralized or distributed production facilities. The diversity of supply ...
