European battery energy storage system (BESS) manufacturer GAZ Energy has partnered with Minespider to introduce digital battery passports across its industrial battery systems ahead of new European Union requirements taking effect in February 2027.
The agreement, announced on October 29, will allow GAZ Energy to link product, compliance and lifecycle information to individual battery systems, providing customers and project developers with access to data throughout their operational lives.
GAZ Energy currently has more than 2 GWh of BESS projects at various stages of implementation across Germany, Finland, Czechia, Poland, Slovakia and Romania.
Under the partnership, Minespider will establish a digital infrastructure connecting each battery system to a persistent identifier, accessible through a physical data carrier such as a QR code.
The system will bring together manufacturer information, product documentation, regulatory compliance records, circularity data and relevant operational information.
Application programming interfaces (APIs) will allow information to be updated throughout a battery’s lifecycle, while public and permission-controlled data layers will determine which information is available to different stakeholders.
The initiative is designed to prepare GAZ Energy for the EU Battery Regulation (EU) 2023/1542, which requires industrial batteries with a capacity greater than 2 kWh to have a digital battery passport from February 18, 2027.
The requirement applies to batteries placed on the EU market or put into service from that date and is intended to improve transparency and access to information throughout the battery value chain.
Nathan Williams, founder and CEO of Minespider, said the value of digital battery passports extended beyond meeting regulatory obligations.
“A Digital Battery Passport becomes much more valuable when the data behind it remains connected to the battery after it enters the market,” he said.
“GAZ Energy is connecting regulatory and product information through persistent identifiers and APIs. That gives GAZ Energy a foundation for the 2027 requirement and for battery data that stays useful across the life of the system.”
David Vodička, a member of GAZ Energy’s board of directors, said maintaining access to information over the long operating lives of energy storage systems was becoming increasingly important.
“Our customers invest in battery systems with a long operational lifetime, and the information associated with those systems needs to remain accessible and useful throughout the project,” he said.
“As our BESS portfolio grows across Europe, we see Digital Battery Passports as an important part of building a consistent and transparent data environment around our systems.”
The companies are also developing the identifier and QR-code structure that will connect individual battery systems to their digital passports.
GAZ Energy said the partnership would support both regulatory compliance and the development of a consistent data management system as its European energy storage portfolio expands.
