Hydrogen production technology, according to the joint EPO-IEA report summarizing patent trends in the hydrogen economy (summarized here), accounts for the largest percentage of patenting activity since 2011 among the three primary stages of the hydrogen value chain (i.e., (i) production, (ii) storage, distribution, and transformation, and (iii) end-use industrial applications). Trends show a shift in hydrogen production from carbon-intensive methods to technologies that do not rely on fossil fuels. The bulk of recent increased patent activity is directed to electrolysis development, while patent activity related to production from biomass and waste has decreased.
