Last week, the European Patent Office (EPO), together with the International Energy Agency (IEA), released a detailed report on patenting activity in electricity storage between 2000 and 2018. An EPO press release is available on the EPO website along with the full report.

In a concerted effort to tackle climate change, countries around the world have proposed to ban conventional petrol and diesel cars within the next few decades, paving the way for an electric vehicle revolution. In our previous blog, The Future Of Automotive Powertrains, we found that in the realm of patents, car manufacturers favour batteries (and lots of them) to power their electric vehicles. In this blog we look at the capabilities and shortcomings of batteries and how fuel cell technology may yet play a part in powering our transport networks.
One of the major problems that faces the emerging electric vehicle (EV) market is the range of electric vehicles. While, due to improvements in battery technology and car design and efficiency, some electric cars now have ranges well over 300 miles, a more comparable level with the range of their internal combustion (IC) cousins, they often come at the cost of, well, a much higher cost than petrol or diesel cars. However, advances recently published in the journal Nature are mapping the route towards a potential solution.
