The article discusses the critical need for societies to transition towards sustainable energy sources due to the detrimental impacts of Greenhouse Gas (GHG) emissions on climate change. Green hydrogen is highlighted as a viable alternative energy carrier that allows for efficient storage and utilization across various industries. Among different production processes, sustainable electrolysis is distinguished as a method that aligns with environmentally friendly practices. In response to the challenge of verifying the provenance and sustainable production of green hydrogen, the article proposes the implementation of a blockchain-based certification system (BLC-CS). This system aims to ensure transparency and secure information sharing between stakeholders in the green hydrogen industry. By leveraging blockchain technology, the certification process becomes more streamlined and trustworthy, enabling producers to comply with regulations for sustainable development. Through a design science research approach, experts collaborate to create an artifact that simplifies the certification process for green hydrogen producers, regulators, and consumers. The proposed BLC-CS facilitates information gathering, verification, and reporting, ultimately contributing to the advancement of sustainable energy practices in the industry. The article concludes with a comprehensive discussion on the feasibility of the blockchain-based certification system for green hydrogen certification. It includes insights on technical extensions, practical recommendations, and outlines directions for future research in this domain. Overall, the sentiment of the article towards the role of hydrogen in sustainable energy practices is positive and forward-thinking.
