The challenges imposed on society require concerted action between energy and climate policies and other government areas, with particular emphasis on the areas of industry and transport, as only then will it be possible to trace a feasible path towards an economy and a carbon-neutral society that is, at the same time, a promoter of economic growth and an improvement in the quality of life. In this context, hydrogen plays a central role, being simultaneously presented as an efficient option to promote, deepen and facilitate the energy transition and as an economic, industrial, scientific and technological opportunity for Europe. In 2016, Portugal assumed the objective of achieving Carbon Neutrality by 2050, having developed the Roadmap for Carbon Neutrality 2050 (RNC2050). This was presented at the end of 2018, in anticipation of the draft of the National Energy and Climate Plan 2021-2030 (PNEC 2030) - the main instrument of national energy and climate policy for the next decade, towards a carbon neutral future - presented in January 2019. The PNEC 2030 is essential to ensure the achievement of energy and climate goals in the next decade, being oriented towards the future and towards Portugal&#39;s long-term goals. In Europe and Portugal, 2019 was a year of intensification of the decarbonization commitment, but it was also the year of public discussion of the initial proposals of the PNECS, which were very much based on pure electrification, which deserved some pockets of resistance in the gas sector. and in any industry. The market has signaled the existence of a gap that can be efficiently filled by hydrogen production.
