Strategic Development of a Hydrogen Supply Chain in Corsica: a Multi-criteria Analysis

A multi-objective framework for hydrogen supply chain (HSC) planning is developed for island contexts, incorporating Mixed-Integer Linear Programming (MILP) over multiple time periods. The model minimizes total system cost, greenhouse gas (GHG) emissions, and a risk index criteria. The case study of Corsica is considered, using Geographic Information Systems (GIS) for spatial analysis and infrastructure locating. The 2050 future design of the HSC is determined including site selection, capacity sizing, and technology choices. The proposed m-TOPSIS-based multi objectives solution shows a decentralized infrastructure with a levelized cost of hydrogen of € $6.55 / \mathrm{kg}$, and greenhouse gas emissions under $2 \mathrm{kgCO}_{2} \mathrm{e} / \mathrm{kg} \mathrm{H}_{2}$. The study also integrates water availability and tourism-induced demand variation as key drivers of energy planning in insular regions.
