Does China's energy storage technology improve economic performance?

Energy storage technology is a crucial means of addressing the increasing demand for flexibility and renewable energy consumption capacity in power systems. This article evaluates the economic performance of China's energy storage technology in the present and near future by analyzing technical and economic data using the levelized cost method.

What equipment is involved in an energy storage system?

To more accurately reflect the technical and economic performance of the energy storage system throughout its entire life cycle, the main equipment involved in the system has been categorized into power conversion equipment, energy storage media, and balance-of-plant components (BOPs).

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.

Is PHS a good energy storage option?

Due to its superior characteristics of high energy capacity and low specific capital cost energy, PHS can be the optimal energy storage option in a large number of operating conditions. It must be noted, however, that pumped hydro storage is subject to hydrology, geography and other conditions.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.

Which energy storage technology has the best economic performance?

When the storage duration is 1 day, thermal energy storage exhibits the best economic performance among all energy storage technologies, with a cost of <0.4 CNY/kWh. Even with increased storage durations, the economic performance of TES and CAES remains considerable. Fig. 8. Economic performance under the day-level energy storage scenario.
