HydroChain: um software protótipo para emissão de certificados de origem para hidrogênio verde em blockchain

Abstract

Faced with the challenges of global warming and the quest for decarbonization driven by the Paris Agreement, Green Hydrogen, produced via electrolysis with renewable energies, stands out as a promising alternative. However, its sustainability and market confidence are hampered by the absence of a national certification process in Brazil and the lack of standardization, despite the relevance of schemes such as CertifHy and the potential of blockchain technology as a “trust machine” for traceability and transparency. To address this gap, this paper proposes HydroChain, a system that issues green hydrogen certificates of origin such as NFTs using blockchain, with the aim of boosting the market and offering digital traceability of production. The system developed improves the credibility and efficiency of certification, serving as a starting point for discussions in Brazil.
