This research investigates the application of hybrid closed-loop energy systems that combine multiple clean energy generation and storage technologies as an alternative to diesel fuel fired electrical generators. The El Hierro project in the Canary Islands, an Archipelago of Spain, represents the first major Megawatt-level energy project aimed at coupling continuous wind power generation with potential energy storage by pumping water to high elevation lakes. These are coupled to hydroelectric generators that can be used for load leveling, peak demand, and frequency control of the power supply to the island's grid. This first of a kind project is presented from technical, regulatory, and political perspective.
