Hydrogen patents for a clean energy future

This study, which combines the expertise of the International Energy Agency and the European Patent Office, is the most comprehensive, global and up-to-date investigation of hydrogen-related patenting so far. Uniquely, it covers technologies for the full range of hydrogen supply, storage, distribution, transformation and end-user applications, as well as introducing new search strategies to compare incremental innovation related to established fossil fuel processes with emerging technologies motivated by the climate challenge. The study is designed as a guide for policymakers and decision-makers to assess their comparative advantage at different stages of the value chain, shed light on innovative companies and institutions that may be in a position to contribute to long-term sustainable growth, and direct resources towards promising technologies.
