Comparative study of energy storage modules

Is thermal energy storage a cost-effective choice?

Sensitivity analysis reveals the possible impact on economic performance under conditions of near-future technological progress. The application analysis reveals that battery energy storage is the most cost-effective choice for durations of <2 h, while thermal energy storage is competitive for durations of 2.3–8 h.

Are energy storage technologies economically viable?

Through a comparative analysis of different energy storage technologies in various time scale scenarios, we identify diverse economically viable options. Sensitivity analysis reveals the possible impact on economic performance under conditions of near-future technological progress.

What are the different types of energy storage systems?

The main research objects chosen for this article include battery energy storage (BES), thermal energy storage (TES), hydrogen energy storage (HES), pumped hydro storage (PHS) and compressed-air energy storage (CAES) (as shown in Fig. 1) to reflect their differences. Fig. 1. Schematic diagram of energy storage system in this study.

How are energy storage technologies compared?

Several works have compared energy storage technologies based only on economic, technical , or environmental aspects .

Are energy storage systems the future of power systems?

Finally, the research fields that are related to energy storage systems are studied with their impacts on the future of power systems. It is an exciting time for power systems as there are many ground-breaking changes happening simultaneously.

What is the LCOE of thermal energy storage?

From 8 h to 16 h, the LCOE of thermal storage is under 0.5 CNY/kWh, making it economically competitive. The LCOS of lithium batteries and thermal energy storage overlap when the duration is between 2 and 4 h, and the economic advantage of thermal energy storage gradually exceeds that of lithium batteries.
