The working group on “Battery Passport for Maritime Batteries” organized by the Maritime Battery Forum is aimed at defining a practical approach for battery passports for the maritime industry according to the EU battery regulations that will come in place from February 2027.
Deliverable
The working group will collaborate on publishing a paper describing a practical approach for implementing a battery passport for battery systems in the maritime industry. The aim of this paper will be to act as a guidance for suppliers, users, and regulators of maritime battery systems to implement a standardized battery passport within the maritime industry.
Planning
The EU Battery Regulations will be effective for batteries put on the EU market from February 2027. The aim is for this working group to finish the paper in 2026 to support all stakeholders in their preparation for the EU Battery Regulations. The MBF will organize monthly meetings to discuss the topics that we need to reach a consensus on within the maritime industry.
20th January 2026 at 3pm CET – Meeting to discuss the readiness of the maritime industry for the Feb 2027 deadline and definition of “Placing on the EU market” for maritime batteries.
Outline WG topics
Each meeting a different challenge will be discussed. Below is an outline of the topics of the planned discussions. As the working group continues these topics or the order of discussing them might be changed, or additional topics can be added.
Timeline -> is the maritime industry ready for the Feb 2027 deadline -> can MBF lobby for an extension for maritime batteries?
Placing on the EU market -> what does it mean for maritime batteries?
Module vs. System level passport (Module level more accurate, easier for maintenance/service, System level less administrative overhead)
Disclosure of sensitive data (from battery cells, battery systems, but also operational data from ships)
Responsibility -> who is responsible and where do the responsibilities lie
Enforcement model
Maritime Battery Recycling and second use, what are common practices and how does this affect the effectiveness of a battery passport
