Technical Economic study for Electricity Production by Using (Tidal-Hydrogen) in Socotra Island, Yemen

Abstract

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.

Sustainable development of Socotra Archipelago. Application and reflexivity

“…Thus, Serag et al (2021) proposed that tidal energy be implemented in Socotra. “Tidal energy is a type of renewable energy source, as tidal movement in oceans is converted into electrical energy by tidal turbines” (Serag et al, 2021, pg. 2).…”

“…While searching for information on the Socotra economy, I found no academic papers or any other reports. Some economic studies can be found about electricity production in Socotra (Alkaf et al, 2010; Serag et al, 2021), and those are the only accessible studies related to the economy of Socotra. It does not come as a surprise that the island suffers from electricity shortages (Alkaf et al, 2010), which I experienced while there.…”

“…On the day of our departure, I had to ask them to leave the electricity on for our phones to charge before we left for the airport. Thus, Serag et al (2021) proposed that tidal energy be implemented in Socotra. “Tidal energy is a type of renewable energy source, as tidal movement in oceans is converted into electrical energy by tidal turbines” (Serag et al, 2021, pg.…”

A SWOT Analysis of the Green Hydrogen Market

“…As expected, the production costs of green H 2 from PV and wind energy remained the highest, with an estimated 3.64 USD/kg H2 . Serag et al [52] performed a techno-economic study on the production of green H 2 using a PEM electrolyzer powered by the tidal movement in the oceans surrounding the Socotra Islands in Yemen. The assessment results showed that the production cost of H 2 was 9 USD/kg H2 , with most of the fault being due to the high electricity costs.…”

“…Figure 6 illustrates the potential for cost reduction in current AWE and PEM electrolysis by combining several stacks to increase the capacity of the overall system, according to the IEA [36]. In IRENA's 2020 report "Green hydrogen cost reduction: scaling up electrolyzers to meet the 1.5 • C climate goal" [52], a detailed analysis of strategies for cost reduction at stack and system levels of electrolyzers, along with their associated challenges and benefits, is presented.…”
