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.
By calculating a single score out of CF and cost, a final recommendation is reached, combining the aspects of environmental impacts and costs. Most of the assessed LIBs show good performance in all considered application cases, and LIBs can therefore be considered a promising technology for stationary electrochemical energy storage.
Fig. 2. Comparative cost analysis of different electrochemical energy storage technologies. a, Levelized costs of storage (LCOS) for different project lifetimes (5 to 25 years) for Li-ion, LA, NaS, and VRF batteries. b, LCOS for different energy capacities (20 to 160 MWh) with the four batteries, and the power capacity is set to 20 MW.
Energy related costs include all the costs undertaken to build energy storage banks or reservoirs, expressed per unit of stored or delivered energy (€/kWh). In this manner, cost of PCS and storage device are decoupled to estimate the contribution of each part more explicitly in TCC calculations.
... Energy storage is even more expensive than thermal units' flexibility retrofits. The lithium-ion battery is the most cost-effective electrochemical storage choice, but its cost per megawatts is 1.28 million dollars, which is much higher than thermal generator flexibility retrofits .
We further analyze the detailed cost composition for the EES, which mainly includes five categories: capital, operation & maintenance, renewable electricity (reference wind electricity), replacement, and contingency ( Fig. 2 c). The capital cost is the most significant part of the EES.
