An EU study examined the electrical situation of Skyros island, Greece. Consideration of various sustainable options yielded an optimal solar/wind power-generation solution, plus hybrid hydrogen systems for the transportation fleet.
Islands are often electrically isolated from mainland grids, requiring independent electricity generation at great cost, thereby increasing the feasibility of otherwise unviable alternative energy technologies. Skyros is one such island and in need of more economical options.
