European Patent Office (EPO) and the International Energy Agency (IEA) have recently published a joint study analysing the innovation along hydrogen value chains. The report is created based on the data from worldwide patents to provide a comprehensive, up-to-date analysis of innovation in hydrogen technologies.
In terms of international patent families (IPFs), which each reflect a high-value invention for which patent applications have been filed at two or more patent offices globally, the report presents the key trends in hydrogen technologies from 2011 to 2020. According to the study, the Europe and Japan, which together accounted for 28% and 24% of all IPFs submitted over this time period, lead the world in hydrogen patenting.
As indicated by the uneven trends in hydrogen-related patenting across technologies and regions, there are chances for governmental action to assist realize a future with net zero emissions.
