The Hague, 10th November 2026: Euro Battery Group (EBG) and Circularise have completed a digital battery passport for the EBG 261 Semi-Solid State LFP (125 kW /261 kWh), its flagship battery energy storage system, shown at the opening of EBG's Energy Hub Binckhaven in The Hague on 10 September 2026. Anyone can scan a QR code on the battery and see what it is made of, where its components came from, and how it should be handled at the end of its life. The passport is in service more than five months before the EU Battery Regulation makes passports mandatory on 18 February 2027. The project was supported by a Digital Product Passport voucher from the Province of Zuid-Holland.
The passport is verifiable by design: each entry can be checked without exposing the commercially sensitive detail behind it. Together, the passport and the Circularise traceability platform cover the complete system rather than the battery alone, taking in the power conversion system, high voltage box, thermal management, edge box, and the fire detection and suppression system. Building one before the rules require it places EBG among the pioneers in European battery storage.
The two companies, both based in The Hague, worked together from June to August 2026 in two distinct parts. The first delivered the passport. Circularise ran a gap analysis against the data Regulation (EU) 2023/1542 requires for stationary industrial batteries above 2 kWh, sorted it into model-level and unit-level attributes, gathered what was missing from EBG's suppliers, and linked the result to a QR code fixed to the battery itself. That work took EBG from a concept-stage reading of the regulation to a validated operational system, a move from technology readiness level 6 to level 8. Alongside the regulated fields, the passport carries EBG's installation and general manuals, product videos, and its certifications, so anyone scanning the code reaches the documentation as well as the compliance record.
"We have spent two years getting inside our own supply chain, because you cannot be transparent about a product you do not control," said Niels Bakker, CEO and Founder, Euro Battery Group. "The passport is where that work becomes visible to a customer. Europe needs its own battery manufacturing, and it will only get there on supply chains it can see into. That is the path we are on."
Battery manufacturers face a practical conflict in the passport rules. The regulation requires them to disclose detailed information about materials and composition, but that same information describes how a product is built, and competitors can read it too. Circularise addresses this with selective disclosure, two levels of access behind the same QR code. The public view carries the safety, carbon footprint, manufacturer, and circularity information the regulation requires, while exact chemical mass breakdowns, dismantling manuals, and other confidential information are released only to notified bodies, market surveillance authorities, and auditors as required by regulation.
The second part went beyond the regulation. Circularise also supported traceability for the components upstream of the battery, mapping the system across multiple levels, from the assembled pack down to individual cells, and capturing more than 30 parameters including serial numbers, manufacturing dates, factory locations, and firmware versions. Each parameter is served from the supplier that owns it rather than copied into a spreadsheet, so it stays current and the supplier stays accountable for it.
None of this is required by the regulation, and most compliance work stops where the law does. Going further is what makes a passport useful rather than merely correct: knowing which cells sit in which unit turns maintenance from scheduled to targeted, ties state of health to the component, and makes second-life assessment a matter of reading a record. Selective disclosure applies to this layer too, so the added visibility costs EBG nothing in supplier confidentiality.
"Parts of the battery passport framework are still being finalised at EU level, which is exactly why it helps to build one early," said Teresa Oberhauser, Head of EU Research and Government Affairs, Circularise. "EBG have a working passport and time to adapt it, rather than a deadline and a blank page."
The Energy Hub is intended as a working showroom, and EBG plans to add further systems to it over time. For other manufacturers in Zuid-Holland facing the same deadline, the project offers a tested route to meeting the 2027 requirements early rather than late.
