Hydrogen patents for a clean energy future

Hydrogen Patents for a Clean Energy Future: A global trend analysis of innovation along hydrogen value chains is the third joint study produced by the European Patent Office (EPO) and International Energy Agency (IEA), following earlier reports on innovation in batteries and electricity storage (September 2020) and clean energy (April 2021).

This latest report uses global patent data to provide a comprehensive, up-to-date analysis of innovation in hydrogen technologies. It is the first study of its kind and covers the full range of technologies, from hydrogen supply to storage, distribution and transformation, as well as end-use applications.
