The work carried out in this thesis aims to evaluate the technical and economic feasibility of producing low-cost green hydrogen in Patagonia Argentina, exploiting wind energy, and ocean shipping to Italy to satisfy the demand of the national steel industry. Two production scenarios have been evaluated, related to the hydrogen demand needed to decarbonise the Direct Reduced Iron production process. The first scenario assumes the replacement of 30 % of Natural Gas with pure Hydrogen. The annual hydrogen demand is 143.144 tonnes. In the second scenario is assumed the total replacement of Natural Gas with pure Hydrogen, to completely abate CO2 emissions.
