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?!
Empowered Through Blockchain Technology
Leveraging blockchain technology, we are developing a decentralized, tamper-proof system that ensures the verifiable tracking of hydrogen’s origin, production method, and carbon intensity. By providing an immutable and transparent record, this approach enhances trust, regulatory compliance, and sustainability within the hydrogen value chain
Optimized for Transparency and Security
We hypothesize that implementing Digital Product Passports will greatly enhance transparency and minimize fraud in the hydrogen market by enabling real-time tracking of key metrics. Early findings indicate that DPPs can streamline certification processes and facilitate cross-border trade by ensuring compliance with international standards
NTFs and Smart Contracts
We employ smart contracts, decentralized identifiers (DIDs), and non-fungible tokens (NFTs) to securely track the lifecycle of hydrogen batches and their associated sustainability data. This approach ensures immutability, transparency, and verifiability throughout the supply chain, enabling precise documentation of origin, production methods, and environmental impact.
