BASE EU: Battery Passport for Transparency & Circularity

BASE stands for the Battery Passport for Resilient Supply Chain and Implementation of Circular Economy. Although central to the green transition of road transport, the battery currently suffers from a supply chain that lacks traceability, sustainability, resiliency, and circularity. Implementing the digital battery passport (DBP) concept in the battery value chain could resolve these issues. The European Digital Battery Passport (DBP) initiative stems from the EU REGULATION (EU) 2023/1542, also known as the EU Battery Regulation (“Regulation”). The main goal of the BASE project is to develop, validate, and implement a working DBP service, as mandated by this “Regulation.” On the data management side, by exploiting distributed ledger technology, BASE will ensure built-in data authenticity verification along the value chain, with no data duplication, avoiding data manipulation, assuring privacy by design, and promoting data interoperability. The DBP will provide up-to-date and accurate data on battery performance indicators, remaining useful life, dismantling, material composition, and safety. The applicability of the DBP will be demonstrated through four pilot use cases in the BASE Project. This project has received funding from the Horizon Europe Framework Programme (HORIZON) Research and Innovation Actions under grant agreement No 101157200.
