The growing focus on sustainable energy solutions has positioned hydrogen as a critical player in the decarbonization of industries. However, ensuring transparency and accountability in hydrogen’s lifecycle, particularly its certification as „green hydrogen,“ remains a challenge. Digital Product Passports, offer a potential solution by providing a secure, immutable record of hydrogen production, distribution, and consumption data. This research project funded by the German Federal Ministry for Economic Affairs and Climate Action aims to explore the role of blockchain in enhancing the traceability and regulatory compliance of hydrogen supply chains.
Distributed Systems
The energy market is inherently decentralized, as energy production and consumption are distributed across numerous locations rather than concentrated in a single hub. This is especially true for renewable energy sources like hydrogen, where generation often occurs close to the point of use, reducing transmission losses and dependency on centralized infrastructure. However, to ensure efficiency, safety, and market stability, regulatory bodies introduce centralized controls. While these regulations are essential, excessive centralization can hinder innovation and slow market growth. Our project leverages blockchain technology to align with the naturally decentralized nature of the hydrogen market. By enabling transparent, secure transactions and enhanced traceability, blockchain supports a distributed energy ecosystem that meets regulatory requirements while fostering innovation, efficiency, and market scalability.
Digital Product Passport
- Track and verify the sustainability of your hydrogen supply chain. Our Digital Product Passport (DPP) leverages blockchain technology to ensure transparency and authenticity in hydrogen production.
- Precise tracking of hydrogen production ensuring compliance with green manufacturing standards.
- Transparent supply chain visibility through blockchain, providing detailed insights into your hydrogen's journey.
- Boost consumer trust and regulatory compliance with immutable and verifiable proof of green hydrogen production.
Why Blockchain for Hydrogen?!
Proof of Origin & Chain of Custody
Hydrogen value chains involve many independent actors—producers, transporters, traders, storage operators, and off-takers. Blockchain creates a shared, tamper-evident record that helps prove where a batch came from, how it moved, and who was responsible at each handover. This reduces disputes, strengthens traceability, and builds trust across the market.
Certification-Grade Compliance & Auditability
“Green hydrogen” claims require evidence that stands up to scrutiny. Blockchain-backed records provide an immutable audit trail linking certificates, measurements, and process data to the corresponding batch and time period. This improves the reliability of compliance reporting, reduces manual reconciliation, and makes audits faster—because stakeholders can verify integrity, not just review documents.
Trusted Sustainability Data
Sustainability attributes—such as production pathway, electricity source, and carbon intensity—are only valuable if they are consistent and verifiable. Blockchain can anchor these metrics to primary evidence and enable selective disclosure: partners can validate the claim without seeing sensitive operational or commercial details. The result is credible sustainability information that supports cross-border trade and informed purchasing decisions.
Latest Events
Proof of Concept
We are excited to announce the rollout of our Proof of Concept for blockchain-based hydrogen tracking. This phase marks a significant step toward validating our approach in real-world scenarios. We aim to demonstrate the effectiveness of our solution in enhancing transparency, traceability, and sustainability across the hydrogen supply chain.
NORDEEP Deep Tech Business Summit (Espoo)
The team presented Blockchain Based green H2 – market (BBH2) at NORDEEP, the Nordics’ deep tech business summit, connecting with startups, research teams, investors, corporates, and public stakeholders to explore collaboration opportunities around hydrogen market digitalization and trust.
ADIPEC 2025 – Low Carbon Innovation
BBH2 was showcased at ADIPEC 2025 in the Low Carbon Innovation Sessions, highlighting a blockchain-based market architecture to build trust in the green hydrogen economy—enabling traceability, certification support, mass balancing, and ESG verification across hydrogen value chains.
Project Wrap-Up & Continued Development
BBH2 is officially finished as a project, but we are still developing it further. We’re building on the results so far, improving the solution, and continuing discussions with stakeholders to prepare next steps toward real-world use.
