On 18 September 2025, the Batteries European Partnership Association (BEPA) hosted a Technology Talk titled “Making the Battery Passport a Reality: from data methodology to deployment.” Farhadur Arifin, Senior Control Engineer and Project Lead at Technovative Solutions Limited (TVS), was one of the speakers representing the BASE project at the webinar.
The webinar brought together leading European projects and experts to discuss how harmonised life cycle data and interoperable digital systems will shape the future of the Digital Battery Passport (DBP). With the EU Battery Regulation requiring passports for all batteries above 2 kWh by 1 February 2027, this discussion could not be more timely.
Technovative Solutions Limited (TVS), a member of BEPA, is playing a key role in the BASE project by developing digital tools such as the Product Environmental Footprint (PEF) calculation tool and data space architecture, ensuring that the Digital Battery Passport is both technically robust and fully aligned with EU regulatory requirements.
The Significance of This Webinar
The Digital Battery Passport is a cornerstone of Europe’s clean energy and circular economy agenda. Its purpose is to ensure traceability, transparency, and sustainability throughout the entire battery value chain. Delivering on this vision requires two pillars: a harmonised approach to life cycle assessment (LCA) that provides reliable and comparable data, and digital platforms that can securely manage and share that information across industries.
This webinar united two flagship Horizon Europe initiatives:
- TranSensus LCA (LCA4Transport): TranSensus LCA (2023–2025) developed a harmonised life cycle assessment methodology for zero-emission vehicles, giving the battery sector a consistent way to measure and compare environmental performance.
- BASE (Battery Passport for Resilient Supply Chain and Implementation of Circular Economy): BASE (2023–2026) is building the Digital Battery Passport, an interoperable platform that ensures traceability, resilience, and circularity across the battery value chain, demonstrated through real-world pilots.
The event highlighted how methodological rigour and digital innovation are being combined to make the battery passport a practical reality.
The Speakers
The event was moderated by Bozorg Khanbaei, Executive Director of BEPA, who highlighted the urgency of moving from pilot concepts to scalable solutions.
From the TranSensus LCA project, Anh-Linh Bui Van, Research Engineer of CEA, presented the consortium’s work in developing a harmonised LCA methodology for zero-emission vehicles. The guidelines provide cradle-to-grave boundaries, standardised functional units, and mandatory impact categories, enabling environmental assessments that are comparable and auditable.
The BASE project was represented by Dr Shahin Jamali of Fraunhofer IEG, coordinator of the project, who introduced the project’s overall framework for building an operational DBP, and Farhadur Arifin of Technovative Solutions Limited (TVS), who gave a detailed presentation on the carbon footprint challenges and solutions that BASE is addressing.
BASE’s Contribution: Turning Regulation into Reality
In his session, Farhadur Arifin explained the regulatory landscape that the industry now faces. From 2025, manufacturers of electric vehicle batteries above 2 kWh must provide carbon footprint declarations, with further obligations for performance classes, labelling, and lifecycle thresholds phased in from 2026 to 2029.
At the centre of this framework is the Product Environmental Footprint (PEF) methodology, Europe’s harmonised approach to life cycle assessment. Unlike conventional LCA practices, PEF requires stricter boundaries, fixed functional units, and compliance with Commission-recognised datasets.
Mr Arifin outlined the obstacles companies must overcome to meet these requirements. Gathering primary data across global supply chains is resource-intensive, especially when datasets for critical raw materials remain incomplete. Modelling end-of-life processes, such as recycling, introduces additional complexity, while ensuring full coverage of the 16 mandatory environmental impact categories presents technical and organisational challenges. On top of this, all results must undergo third-party verification, raising the compliance burden further.
BASE is tackling these issues head-on. He highlighted how the project is developing a secure and interoperable data space that enables companies to share information without losing sovereignty over their data. Within this architecture, EF-compliant datasets are being integrated alongside quality assessment mechanisms to ensure reliability.
BASE is also building a dedicated PEF calculation tool linked to the Digital Battery Passport, allowing manufacturers to generate compliant declarations consistently and efficiently. By embedding these tools into the DBP platform, BASE is not only supporting regulatory compliance but also enabling predictive analytics on battery performance, safety, and circularity.
Mr Arifin emphasised that the project’s ambition is to create a system that industry trusts, regulators recognise, and society benefits from: a Digital Battery Passport that makes compliance achievable while adding value across the supply chain.
TranSensus LCA’s role
The TranSensus LCA project (2023–2025) was presented by Anh-Linh Bui Van of CEA. This Horizon Europe initiative set out to create a harmonised life cycle assessment (LCA) methodology for zero-emission vehicles, addressing the long-standing issue of inconsistent and non-comparable environmental assessments across the sector.
By defining cradle-to-grave system boundaries, standardised functional units, and mandatory impact categories, TranSensus LCA has delivered a consolidated set of guidelines that industry and researchers can apply. For the battery industry in particular, the project’s outcomes provide the methodological backbone needed to measure and compare the environmental footprint of batteries on a consistent basis.
This is critical not only for regulatory compliance under the EU Battery Regulation but also for enabling more transparent supply chains and informed decision-making across the value chain.
Looking Ahead
The BEPA Technology Talk showcased how far Europe has progressed in bringing the Digital Battery Passport to life. TranSensus LCA is setting the methodological standards, while BASE is building the operational tools and testing them in real-world pilots spanning automotive, maritime, and stationary storage applications.
The message from the webinar was clear: delivering the Digital Battery Passport is not only about meeting regulatory obligations, it is about strengthening Europe’s industrial competitiveness, advancing circular business models, and ensuring that batteries play their full role in the green transition.
