Innovation trends in electrolysers for hydrogen production

This joint study by the EPO and the International Renewable Energy Agency (IRENA) uses patent statistics to reveal the trends and dynamism in the field of hydrogen that can be produced using renewable electricity. Renewables-based hydrogen can be used in the chemical sector and as a fuel. It is abundant and can be obtained through the electrolysis of water in the presence of electrocatalysts. This makes hydrogen very attractive as a green energy source, provided that its production is green too.
