A test bench for the production of green hydrogen and its traceability and certification using blockchain technology

The energy transition is a challenge in which all countries in the world are involved to date with the aim of achieving climate neutrality. Green hydrogen produced by electrolysis through energy from renewable sources, can play a key role in the energy transition replacing fossil fuels used in industrial processes and heavy-duty transport. The widespread diffusion and massive adoption of this new and clean fuel, as well as the creation of national, regional, and international markets, depend heavily on traceability tools that certify its origin, creating transparency and stimulating demand. In this context, new information technologies such as Blockchain, thanks to their characteristics, could solve the problems associated with the traceability of green hydrogen, thus contributing to its diffusion. This paper describes a laboratory-developed system for green hydrogen production via electrolysis and proposes a Blockchain architecture for its tracking and certification.
