The integration of Blockchain Technology (BCT) into the Hydrogen Supply Chain (HSC) is of paramount importance, as it not only strengthens the infrastructure against inefficiencies but also establishes a foundation of trust and transparency critical for the large-scale adoption of hydrogen as a clean energy source. This study explores the role of blockchain technology in enhancing the HSC for sustainable energy. It suggests blockchain can simplify and secure the supply chain, making hydrogen a more prominent part of our energy solutions. The research identifies how blockchain’s features, like smart contracts, could improve efficiency and reduce costs. Through examining case studies, the study reveals how blockchain integration can tackle industry challenges. In summary, the research positions blockchain as key to advancing a sustainable hydrogen economy and driving the energy sector towards a greener future.
