The consequences of the climate crisis and the increasing energy demand make the energy transi-tion crucial and necessary. Green hydrogen has a significant potential for a low-carbon energy transition. New policies and strategies emerge in line with energy transition and hydrogen poli-cies. This study has presented a model-based outline for the global green hydrogen supply and trade infrastructure in 2050 focusing on supply cost and potential using a cost minimization linear pro-gramming (LP) model which is implemented in the General Algebraic Modeling System (GAMS) with two scenarios. The results of the Hydrogen Policies Scenario are presented which examines today's hydrogen strategies and initiatives, as well as where the evolution of current technologies could take the hydrogen and energy sectors in 2050. The global hydrogen trade volume reaches 605 Mt (megaton) hydrogen trade per year, with North Africa dominating at 210 Mt. In conclusion, solar power and pipeline infrastructure will be the decisive force of the expansion of the global hydrogen trade.:Concept Methods Hydrogen Policies Conclusion Results
