摘要:The great need to use electricity at present and to ensure its continuity in future requires finding renewable and sustainable sources; the best of those sources are renewable energy sources such as wind energy, solar energy, and tides. All research focuses on studying those sources for each region to give the complete database that can rely upon in future to build projects generating electric power according to accurate scientific studies, specifically in areas far from the main electricity grid, such as remote islands, including Socotra Island, which, like other Yemeni cities, suffers from a severe crisis to access electricity. Energy storage is a natural thing when using renewable energy due to seasonal change, daily and hourly in these sources; one of the best ways of storing is the production and storage of hydrogen for use at peak periods or any other benefits. Economic information is still incomplete about the production of electricity by hydrogen, especially in the Middle East region, which considers that the primary source of electricity is only fossil fuels. This paper gives a study of the level of tides on Socotra island, and a technical study of the possibility of producing electricity using this renewable source according to its efficiency, and an economic assessment of electricity generation by (Tidal-Hydrogen) for this island.
