The Role of Hydrogen Trade Openness in the Transition to Low-Carbon Economy 1: IFP Energies Nouvelles, France; 2: Economix-CNRS, University of Paris Nanterre, France According to the International Energy Agency (IEA), reaching Net-Zero emissions target by 2050 requires a deep penetration of hydrogen, and is expected to represent 12% of global final energy consumption. However, this deployment faces constraints on both supply and demand scale up, and matching. In this paper, we ask if global hydrogen trade liberalization enables the optimal hydrogen production capacities deployment in a carbon-neutral energy system by 2050. Combining an energy system least-cost optimization model (KiNESYS-IFPEN) with an adapted logistic diffusion model with uncertainty on parameters, we find that, while regionally impactful, global hydrogen trade openness has limited effects globally. The distribution effect across regions dominates since several specialize themselves as exporters (Middle East, Latin America, Australia and Africa), or as importers (Europe and East Asia). This effect is stronger when combined with investment costs reduction in electrolysers and longer expectations on future hydrogen market size. These results highlight the trade-off between achieving least-cost regional energy transition and ensuring hydrogen supply security. | |
