The European Patent Workplace (EPO) and the Worldwide Power Company (IEA) launched a brand new report on hydrogen tech patents. They word an increase in electrolysis innovation and say automakers and chemical suppliers are main the best way in hydrogen patents.
Europe and Japan lead when it comes to new international hydrogen patent functions within the 2011-20 interval, based on a brand new report by the IEA and the EPO.
Japan is the area the place the variety of new hydrogen patents elevated on the quickest tempo all through the 2011-20 interval, with a compound common development price of 6.2%. America is the one a part of the world the place the variety of patents has decreased over the identical interval.
South Korea and China account for about 6% and 4% of whole patents, however they present sturdy development, with common annual development of 12.2% and 15.2%, respectively. South Korea, particularly, is specializing in rising end-use functions for hydrogen.
The European chemical trade, primarily in Germany and France, dominates the innovation of established hydrogen applied sciences. Nonetheless, the brand new hydrogen patent heavyweights are primarily Japanese and Korean corporations within the automotive and chemical sectors. Such corporations are likely to deal with electrolysis and gas cell applied sciences.
“About half of the worldwide patent households (IPFs) on hydrogen applied sciences within the interval 2011-20 are associated to hydrogen manufacturing,” stated the IEA and the EPO. “Different IPFs are divided between end-use hydrogen functions and applied sciences for hydrogen storage, distribution and transformation.”
Patenting has shifted from fossil fuel-based tech to low-emission strategies. The report famous a rise in innovation in electrolysis expertise. Japan leads in patents on alkaline and PEM applied sciences between 2011 and 2020.
“The EU 27 and different European nations are energetic in patenting and manufacturing – particularly in SOEC applied sciences – whereas additionally making important contributions when it comes to PEM and alkaline applied sciences,” stated the IEA and the EPO.
Each establishments name for sturdy insurance policies to make low-emission hydrogen cost-competitive. They word that technological advances all through the worth chain are vital for hydrogen to play a “bigger function” within the power transition.
