Europe is at the forefront of innovation in electricity grid technology, sharing the lead with Japan in global patent filings over the past decade. According to a joint study by the European Patent Office (EPO) and the International Energy Agency (IEA), the European Union accounted for 22% of all grid-related patents from 2011 to 2022. However, the rapid ascent of China, now the top global region for grid-related patents, has created fierce competition in this critical field.
The report, Patents for Enhanced Electricity Grids, highlights how the race to modernize electricity grids is accelerating as nations embrace clean energy transitions and integrate digital innovations. The study reveals that patents for grid technologies have surged sixfold since the early 2000s, with AI-driven solutions leading the charge. Between 2010 and 2022, patents incorporating smart features into grid designs rose by 50%, with electric vehicle charging and supply-demand forecasting emerging as key growth areas.
Europe’s commitment to cutting-edge grid technology is underscored by its global leadership in patents. Within the region, Germany leads with 11% of grid-related patents, followed by Switzerland, France, the UK, and Italy. Startups and research institutions play a pivotal role, with 37% of Europe-based grid-tech startups applying for patents—far outpacing the average for other European startups.
António Campinos, President of the EPO, emphasized the strategic importance of these developments. "Europe must take the lead in new clean technologies to secure its economic competitiveness. Smarter, more flexible electricity networks are essential to meet growing power demands while balancing the variability of renewable energy sources," he said.
China's share of global grid-related patents has grown from just 7% in 2013 to a staggering 25% in 2022, surpassing the EU for the first time. This growth reflects the nation’s aggressive investments in clean energy infrastructure and innovation, positioning it as a formidable player in the global energy transition.
The IEA's Executive Director, Fatih Birol, highlighted the global stakes. "Inadequate electricity grids are a barrier to economic activity and clean energy deployment. The rapid rise of China in this space signals a new era of competition for other regions," he said.
The report stresses that grid technology innovation must continue at pace to overcome the challenges posed by aging infrastructure and rising energy demand. Europe's robust patenting activity and strong ecosystem of startups and research institutes provide a solid foundation for maintaining its leadership. However, as nations race to develop more efficient and flexible grid solutions, sustained investment in innovation is essential.
