Somalia Supercapacitor Energy Storage System

HRES systems based entirely on RE sources and pumped hydro storage can be regarded as a highly suitable approach to addressing the global environmental challenges posed by conventional energy resources, particularly in Somalia. However, several challenges must be addressed before the proposed system can be implemented in the Hobyo Seaport area.

For instance, supercapacitors are currently employed in hybrid systems for buses and trucks, storing regenerative braking energy of light rails and automobiles, heavy-duty vehicles, industrial power, consumer electronics, and load-balancing systems for fluctuating energy sources. [16, 36, 38]

This comprehensive review has explored the current state and future directions of supercapacitor technology in energy storage applications. Supercapacitors have emerged as promising solutions to current and future energy challenges due to their high-power density, rapid charge-discharge capabilities, and long cycle life.

While RE systems have been widely studied, Somalia's unique geographical and socio-economic context, particularly for seaport energy needs, remains underexplored. Existing research on HRES in Somalia has focused mainly on rural electrification, with limited attention to critical infrastructure like seaports.

A supercapacitor has owned some internal resistance, resulting in energy loss. It can be modeled as a system consisting of a capacitor in series with a resistor (RES), as depicted in Figure 10. The RES is the resistance of the electrochemical capacitors and is important in reflecting the energy efficiency and power performance of supercapacitors.

Hybrid supercapacitors combine battery-like and capacitor-like electrodes in a single cell, integrating both faradaic and non-faradaic energy storage mechanisms to achieve enhanced energy and power densities .
