A CleanTechnica open letter addressed to top European Commission leaders argues that Europe’s battery strategy is at a decisive moment. It recalls that by 2021 Europe began trying to establish a European battery value chain, and that companies invested billions based on promises from policymakers.

The letter frames the current situation as a test of whether “Made in Europe” means anything in practice. If those early commitments are not backed by concrete action, the credibility of the entire European battery project could be called into question.

No other source is included, so the article reflects only the letter’s argument. The central claim is straightforward: Europe’s battery ambitions will be judged by whether it honors the promises that drew private investment in the first place.
