Pre-feasibility analysis of an energy supply system for Southern Europe: Technical aspects

Abstract

Technical aspects of the feasibility of energy transmission from hydroelectric power plants in Zaire to southern Europe, and to Italy in particular, have been studied. Three alternatives were considered: electric power transmission, gaseous hydrogen pipeline, and methylcyclohexane/toluene loop cycle. The technical feasibility of each alternative, also for a mid-term prospect, and energy losses were examined and evaluated. A comparison, from an energetic point of view, was also carried out among the three systems by varying the ratio between hydrogen and electric power required by the users. The high values of the energy transmission factor make this energy supply system very attractive. Depending on the sharing of the energy required for final uses, a double transportation system, based on electric power together with hydrogen, could be convenient. Indeed, if a very high amount of hydrogen is required by the users, a system based on hydrogen would be preferable.
