New energy storage field enters scale

On September 12, the National Development and Reform Commission and the National Energy Administration released the “ New Energy Storage Scale Development Action Plan (2025-2027)”, which clearly proposes that by 2027, new energy storage will basically achieve scale and market-oriented development, with technological innovation and equipment manufacturing capabilities remaining at the forefront globally.

How big is the energy storage scale required for a power station

To determine the necessary energy storage capacity of a power station, various factors must be considered, including 1. the energy demand profile, which indicates how much power is required over time, 2. the generation mix, encompassing the types of energy sources being utilized, and 3. the desired unit’s operational flexibility, affecting the speed at which energy can be dispatched.

Extra large energy storage capacitor

Yet, commercial electrical double layer capacitor (EDLC) based supercapacitors exhibit low energy densities and a moderate operating voltage window, which leads to large numbers of cells being connected in series to achieve the desired power and meet the energy demand, ultimately increasing the production cost of the supercapacitor-based ESS.6 Therefore, continuous research efforts are needed in terms of increasing energy densities and widening the operating voltage window of the EDLC devices.7 Supercapacitors can be classified into three types: (1) EDLCs, (2) pseudocapacitors, and (3) hybrid supercapacitors.8 (Fig. 1) Amongst the three types of capacitors, EDLC-based supercapacitors are considered the most appropriate for the ESSs as the EDLC offers the most stable charge storage capability for long-term cycling which is the most important criterion for fabricating high performance and stable ESSs.
