Feasibility into hydrogen and fuel cells technology for the Principality of Andorra

(ENG) The Principality of Andorra (PoA), a small country of 468 Km2, with a main road of 40 Km of length that crosses the territory, placed in the middle of the Pyrenees, is practically foreign energy dependent. On the one side, it has a hydropower plant that generates 15% of the annual electricity consumption, and two high-voltage lines of 110 kV for electricity imports, which comes from France and Spain respectively. On the other side, the dependence is total from the hydrocarbons fuels used by heating and transport, approximately 56% comes from Spain and 40% from France. For gas, 50% from Spain and 50% in France. Because of this situation, this document investigates the feasibility of employing a H2 and FC technology system involving water electrolysis, metal hydrides storage, and the heat and power cogeneration (CHP) via fuel cells (FC), into the energy system of Andorra as an opportunity to improve the country's energy security. Positive and negative findings (technological and economic) from the study are discussed and analysed, as well as considering increase in prices of traditional energy sources. Different energy sources are also discussed and analysed, driving to a five proposal for generating different percentages of energy consumption of the country.
