Digital Battery Passport

Madrid, Spain – April 23, 2025 –At MOTORTEC Madrid, Partisia Blockchain today unveiled its groundbreaking Digital Battery Passport, a blockchain-enabled solution coupled with programmable confidentiality technology, co‑developed with TERA Batteries, DuoKey and Quantum Brand Protection (QBP). 

Built for full compliance with EU Battery Regulation 2023/1542 (effective February 2027), this industry‑defining decentralized system fuses upgradeable NFTs, multi-party computation (MPC) key‑management and tamper‑proof physical authentication to accelerate sustainable circular‑economy models in the battery sector.

Why this matters?

This Digital Battery Passport brings the following, to an entire continental economic area (Europe):

  • Regulatory Readiness: Delivers comprehensive tracking. Through materials provenance, carbon footprint, performance metrics and supply chain due diligence, this collaboration ensures audit ready compliance from manufacture through to end-of-life and beyond i.e recycling.
  • Selective Privacy & Transparency: Partisia Blockchain issues updatable NFT twins on a permissionless ledger with privacy enhancing capabilities baked in. DuoKey’s MPC secures cryptographic keys while QBP’s Q-Stamp QR codes anchor each digital identity to its physical battery.
  • Circular Economy Activation: Real-time, verified state-of-healt data powers second-life applicationsm optimizing recycling, and enables battery trading markets – without exposing proprietary data.
  • Market Impact: Europe’s battery market is forecasted to exceed €250 billion by the end of 2025. Position your operations ahead of regulations and unlock new revenue from reused and recycled assets.

Kurt Nielsen, co-CEO & co-founder, Partisia Blockchain also added,

“By tokenizing batteries on Partisia blockchain, we are enabling new circular economy business models. The immutable and transparent nature of blockchain technology ensures that data integrity is maintained throughout the battery’s entire lifecycle, from manufacturing through repurposing and recycling.”

Their involvement brings credibility and industry insights to the collaboration. With a direct connection to evolving battery regulation and recycling challenges, they provide a crucial link between compliance objectives and real-world application.

“Our Digital Battery Passport not only meets regulatory requirements but also provides meaningful value throughout the battery lifecycle. This collaboration brings together best-in-class technologies to deliver a secure, transparent and compliant solution for battery manufacturers.”
– David Santiago, CEO, TERA Batteries

DuoKey, a leading enterprise security provider specializing in key management and Multi-Party Computation (MPC). Its cryptographic infrastructure protects sensitive business and industrial data, allowing organizations to compute encrypted information without exposing underlying values. DuoKey ensures that battery passport data remains secure, verifiable and importantly auditable.

“The combination of DuoKey’s Multi-Party Computation technology with Partisia’s privacy-preserving blockchain creates an unparalleled security framework for managing battery data. This ensures that sensitive data remains protected while still enabling full regulatory verification”
– Nagib Aouini, CEO, DuoKey

Quantum Brand Protection (QBP) delivers cutting-edge anti-counterfeiting and authentication technologies. Their proprietary Q-Stamp system connects physical products to digital records through their tamper-proof QR codes. By providing secure markers for each battery, QBP ensures physical traceability and lifecycle authentication even in offline or recycling environments.

“This innovation provides durable, physical tamper-resistant authentication throughout the battery’s entire lifecycle, including recycling and refurbishing stages.”
– Dr. Nasser Hefiana, CEO of Quantum Brand Protection

About Partisia Blockchain & Our Contributions

Partisia Blockchain is next-gen public blockchain engineered for trust, privacy and speed-of-light finalization. It’s the first to combine secure multiparty computation with zero-knowledge processes and confidential smart contracts at scale, enabling a web3 with programmable confidentiality.

Maintained and developed by a Swiss Foundation, Partisia Blockchain provides the open-source infrastructure which underpins and enables the confidentiality components of the Digital Battery Passport.

This partnership provides a solution that enables stakeholders to meet and exceed the requirements of the EU Battery Regulation, whilst also opening the door to entirely new business use cases. This allows batteries to be tracked, monitored, verified and traded across different markets with reliable data baked in. It not only ensures that companies are compliant but helps manufacturers and recycling organizations unlock value from products that were previously difficult to trace. A key step in both the automotive industry and broader applications to supply chain management.

Our public blockchain network provides the following:

  • Updatable NFTs: Immutable digital twins that evolve with each battery’s lifecycle event while creating clear audit trails.
  • Zero‑Knowledge Proofs: Granular, selective, disclosure. Ensuring regulators are satisfied, while protecting commercial secrets.
  • Decentralized Governance: A multi‑node infrastructure prevents any single party from controlling the Digital Battery Passport ecosystem.

Conclusion

Live demonstrations of the Battery Digital Passport will be available at the TERA Batteries booth at MOTORTEC Madrid from April 23 to 26, 2025.

The TERA NOMAD 3R portable power station, identified with its digital passport, will be showcased, giving attendees the opportunity to experience the potential of the applied technology, which anticipates the 2027 regulatory deadline.

With this passport, we’ve proven that blockchains can be both confidential and transparent. This passport is the first real‑world asset use case that delivers on that vision at scale, transforming how regulated industries can approach compliance and sustainability simultaneously.”For more information please visit Duokey’s Medium blog here.
