Green hydrogen is gaining global momentum as a cornerstone of the energy transition. Its production, utilization, and trade require a robust regulatory framework to ensure safety, quality, and market access. This report examines international and regional regulations, standards, and guidelines relevant to green hydrogen, with particular emphasis on adapting them to the Jordan context. It synthesizes European Union (EU) directives, International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) standards, as well as U.S. and international best practices. It compares these regulations with Jordan’s current regulatory landscape. Drawing on the Draft National Green Hydrogen Strategy for Jordan (2023) and the World Bank’s 2025 policy note, this review identifies critical gaps, proposes an adaptation roadmap, and explores how Jordan can position itself as a regional and export-oriented hub.
