dc.description.abstract | Despite the potential of hydrogen as a sustainable energy carrier, existing studies analysing the recent evolution
of this technology are scattered, typically focusing on a specific type of hydrogen technology within a single
country or region. In this paper, we adopt a broader perspective, providing an overview of the evolution of
knowledge generation across different types of hydrogen fuel, and the leading countries in developing new
technologies in this field. Using data from the European Patent Office, we map knowledge generation on
hydrogen fuel technologies, exploring its geographic distribution and its link with environmental sustainability.
While the United States leads the generation of new knowledge, other Asian and European countries show
greater dynamism in growth and specialisation. Our study shows that although hydrogen fuel is considered
environmentally friendly, most recent technological developments are still related to fossil energy sources.
However, a faster growth rate is observed in the knowledge of hydrogen fuel from renewable sources, pointing to
a promising path towards sustainability. Moreover, our analysis of the knowledge interconnection between
different hydrogen types suggests that those technologies developed for hydrogen based on fossil energy sources
have enabled novel applications based on renewable energies. | es |
