Innovation trends in electrolysers for hydrogen production
On May 2022, the European Patent Office (EPO) and the International Renewable Energy Agency (IRENA) published a joint report on innovation trends in electrolysers technology. This IRENA Insight Webinar will present the main findings of the report and the patent methodology used for the analysis.

The report analyses patent statistics to reveal the trends and dynamism in the exciting field of hydrogen that can be produced using renewable electricity via electrolysis. The great momentum observed in electrolysers is expected to continue and to spur future innovation. In fact, the rising trend in patent filings signals that more will come soon, addressing the urgent need for new solutions to lower the cost of electrolysers in parallel with raising technological efficiency and production capacity.

Electrolysis of water, using renewable electricity, is the sustainable option to produce green hydrogen as an attractive low-carbon energy carrier. To respond to the growing demand for renewables-based hydrogen, an extraordinary expansion of the market for electrolysers is needed linked to a significant capacity increase in the manufacture and deployment of electrolysers. A rapid reduction in electrolyser system costs is essential and technology innovation is crucial to this end.
