Europe has set ambitious decarbonisation targets for its power and transport sectors. Batteries can play a crucial role in reaching these targets, allowing the integration of variable renewable sources in the European power market and enabling the emission reduction of the transport industry. This insight takes a closer look at the emerging European battery industry to estimate Europe's battery supply and demand until 2040. By distinguishing between the domestic and non-domestic battery and mining capacity production, the report highlights if Europe can secure a self-sufficient and sustainable battery industry. The findings shed light on market bottlenecks and outline strategic takeaways for different industrial players and governmental parties.
