In the past few decades, electricity production depended on fossil fuels due to their reliability and efficiency [1].Fossil fuels have many effects on the environment and directly affect the economy as their prices increase continuously due to their consumption which is assumed to double in 2050 and three times by 2100 [6] g. 1 shows the current global
Accordingly, the European Commission has recognized electricity storage 1 as one of the strategic energy technologies in SET-Plan in achieving the EU׳s energy targets by 2020 and 2050 .
The costs of purchasing power in charging phase is not included in the estimations, as it directly depends on the market and application of the asset. The range of natural gas prices in the examined literature varies between 8 and 20 €/MWh, while the emission costs were between 18 and 22 €/ton CO 2.
The results indicated that mechanical energy storage systems, namely PHS and CAES, are still the most cost-efficient options for bulk energy storage. PHS and CAES approximately add 54 and 71 €/MWh respectively, to the cost of charging power. The project׳s environmental permitting costs and contingency may increase the costs, however.
The results indicate that underground CAES offers the lowest capital costs (893 €/kW) for bulk energy storage systems, followed by Ni–Cd and Fe–Cr batteries, 1092 and 1130 €/kW, respectively. For power quality applications, SCES and SMES show the lower costs, 229 and 218 €/kW, respectively.
In terms of TCC (total capital cost), underground CAES (with 890 €/kW) offers the most economical alternative for bulk energy storage, while SMES and SCES are the cheapest options in power quality applications. However, the cost data for these electro-magnetic EES systems are rather limited and for small-scale applications.
This new setting has imposed technical, economic, and environmental challenges for secure supply of electricity. Energy storage is deemed as one of the solutions for stabilizing the supply of electricity to avert uneconomical power production and high prices in peak times.
