The EU Battery Passport Conference 2026 took place on 4th February 2026 in Lille, France. This was Europe’s first dedicated forum focusing exclusively on readiness and technology in preparation for the upcoming Digital Battery Passport (DBP) requirements under the EU Battery Regulation (Regulation (EU) 2023/1542).
With the February 2027 compliance deadline approaching, discussions moved decisively beyond theory. The conference addressed a pressing question for the entire battery value chain:
“How can Digital Battery Passports move from regulatory requirement to scalable, real-world implementation?”
Ingrid Flatebø Holsen, Project Lead for Battery Passport at Corvus Energy, represented Corvus Energy and the BASE project’s maritime use case at the event, joining a panel discussion titled “The Future of Battery Transparency: How Digital Product Passports Will Reshape the Entire Value Chain.”
She was joined by Dr Fahim Chowdhury, CEO of Technovative Solutions Ltd., and Farhadur Arifin, Senior Control Engineer at Technovative Solutions Ltd. and Technical Manager of the BASE Project, for a cross-industry dialogue exploring both strategic direction and practical implementation challenges surrounding Digital Battery Passports. The session was moderated by Salauddin Sohag, Managing Director of DigiProd Pass Ltd.
Following the event, we spoke with Ingrid Flatebø Holsen to gain deeper insight into the maritime perspective on battery transparency and implementation readiness.
Interview with Ingrid Flatebø Holsen
Q1. How would you describe your overall experience at the EU Battery Passport Conference 2026 and the panel on “The Future of Battery Transparency: How Digital Product Passports Will Reshape the Entire Value Chain”?
The experience at the EU Battery Passport Conference was very positive and inspiring for me. I had the opportunity to meet people deeply involved in implementing battery passports across different industries. We’re all dealing with similar questions, uncertainties, and technical challenges, and being able to openly share experiences through panels, presentations and networking was incredibly valuable.
Q2. As Project Lead for the Battery Passport at Corvus Energy, what did the discussion reveal about the practical challenges of implementing Digital Battery Passports in real industrial settings?
One of the main takeaways was that organisations across sectors are facing similar challenges. There are still unknowns regarding responsibilities, data availability, evolving standards, and the regulation's interpretation.
However, the consistent message was clear: start with what you have and build from there.
For me, it was reassuring to recognise that Corvus Energy is not alone in navigating an evolving regulatory landscape. At the same time, it was encouraging to see that the topic is maturing quickly. Even if the first version of a Battery Passport may be simplified, early readiness will be important to remain competitive and compliant.
Q3. Within the BASE project, Corvus Energy leads the maritime use case. What key lessons from this work demonstrate how battery transparency can function in practice?
Through the BASE project, we have learned that the Battery Passport must function as a living asset, not just a static certificate.
Maritime batteries generate operational data continuously. Capturing and updating this information provides real value for safety, performance monitoring, and long-term lifecycle management.
The project also explores how transparency around key product information — from material composition and carbon footprint to manuals for repair, repurposing, and disassembly — can significantly reduce administrative burden. When stakeholders across the value chain have access to consistent, verified information from a single trusted source, processes become faster, clearer, and more reliable.
Through the BASE project, we demonstrate that the Battery Passport can go beyond regulatory compliance by enabling measurable improvements in operations, safety, and sustainability, while laying the foundation for circularity.
Q4. How did the audience respond to the maritime perspective during the panel, and what questions or discussions stood out during networking sessions?
The maritime perspective was very well received, particularly because it highlighted challenges that differ from the more mature EV sector. Many attendees noted that maritime battery systems bring additional complexity due to demanding operating conditions and the involvement of multiple stakeholders across the value chain.
During networking discussions, there was particular interest in how operational vessel data can be shared securely, how responsibilities are divided between shipyards, integrators, manufacturers, and operators, the role of classification societies, and how granular the Battery Passport should be for large maritime battery systems.
Q5. How can Digital Battery Passports support safety, lifecycle management, and circularity for maritime battery systems?
Digital Battery Passports can play a significant role in strengthening safety, lifecycle management, and circularity for maritime battery systems when supported by verified, up-to-date data throughout the battery’s life, helping ensure that operators, service personnel and regulators always have access to reliable information.
From a safety perspective, the DBP enables traceability of manufacturing data, commissioning records, maintenance events, and incidents, supporting better risk assessment and safer vessel operations.
For lifecycle management, access to performance insights helps optimise maintenance strategies and strengthens warranty and service processes.
In terms of circularity, key information about composition, carbon footprint, repairability, and remaining capacity becomes easily accessible. This simplifies decisions related to reuse, repurposing, and recycling at the end of life, while increasing trust in second-life applications.
Q6. Based on the discussions at the conference, what should maritime battery manufacturers and operators prioritise in the next 12–18 months to prepare for implementation?
Over the next 12–18 months, stakeholders in the maritime battery industry should focus on structured preparation.
Ensure data readiness: Understand what data is currently available, where it resides, and who is responsible for maintaining it.
Establish clear responsibilities: Establish internal governance and clarify responsibilities across the value chain, including shipyards, integrators, operators, and service partners.
Ensure technical readiness: Focus on technical readiness, including enabling QR code functionality so batteries can be linked to their Digital Battery Passport once systems are fully implemented.
Get started: Begin with a simplified version rather than waiting for complete certainty
Monitor evolving regulation: Stay aligned with delegated acts and developing industry standards as the framework continues to mature.
Q8. From your perspective, how does attending and actively contributing to events like the EU Battery Passport Conference help advance the battery industry as a whole?
Events like the EU Battery Passport Conference play an important role in moving the industry forward. By sharing practical experiences, challenges, and early lessons across sectors, we help create a more aligned understanding of what battery passports need to support in real applications.
Contributing to these discussions ensures that the maritime perspective is represented and that emerging standards and solutions reflect the realities of a broader range of use cases. It also strengthens collaboration across the value chain, which is essential for building trusted and interoperable approaches to transparency.
