In response to the growth in population, energy demand (particularly in the transport sector), and fossil fuel prices, Reunion's energy transition is based on the massive use of renewable resources. Currently, a large part of the local renewable electricity comes from converting solar and wind resources. However, the intermittency of these resources leads to storage and distribution problems, which can be solved using hydrogen, recognized as a flexible and clean energy carrier. Mainly used in the chemical and refining industries, this energy carrier could contribute to decarbonizing some industrial sectors, producing electricity, or supplying a part of the energy needs for the transport sector. Considering the potential of wind energy in Reunion and the high energy consumption level in the transport sector, producing electrolytic hydrogen powered by wind turbines is a promising alternative for developing green mobility. The present study aims to evaluate the potential of electrolytic hydrogen production, powered by wind resources, for heavy mobility in Reunion Island. The study includes (1) the estimation of the annual requirement of hydrogen to cover the needs of the heavy transport sector and (2) the determination of the wind energy necessary to meet these needs. Based on the hydrogen energy needs for heavy mobility, the results of the study will allow the selection of the most suitable locations for the implementation of wind farms based on the energy potential. This study provides insight into a prospective strategy for energy transition within the transport sector of a geographically isolated island by using hydrogen derived from wind resources. The inherent challenge of intermittency of climaterelated renewable resources, such as wind, could be potentially mitigated by employing hydrogen as an intermediary mechanism for storing and distributing intermittent energy.
