MUNICH: A joint report by the European Patent Office and the International Energy Agency found that found that the average annual growth rate of patents for low carbon emissions technologies has fallen to 3.3 percent since 2017, considerably slower than the average level of 12.5 percent in the period 2000-2013.
It said that"the energy sector will only reach net-zero emissions if there is a significant and concerted global push to accelerate innovation." The key driver of patent growth since 2017 has been innovation in cross-cutting technologies such as batteries, hydrogen and smart grids, along with carbon-capture, use and storage .
