Patents for green hydrogen technology on the rise: IRENA

Patents for green hydrogen technology on the rise IRENA

A joint study published today (12 May) by the International Renewable Energy Agency (IRENA) and the European Patent Office (EPO) uses patent statistics to reveal the trends and dynamism in the field of hydrogen that can be produced using renewable electricity via electrolysis.

Innovation trends in electrolysers for hydrogen production shows that patent filings for hydrogen production technologies have grown on average by 18% each year since 2005.

The new report tracks the evolution of patent filings over the last 15 years and highlights several trends, including:

The demands for cleaner energy have never been greater. Although patent filings show a steep increase, the report underlines that major innovations in electrolyser technology are still needed to further reduce its costs and make it market-ready at industrial levels. With its charts and commentary, today’s report is useful to technologists, companies and investors wanting to better understand these rapidly expanding technology domains.
