Energy storage technology investment comparison

Why is it important to compare energy storage technologies?

As demand for energy storage continues to grow and evolve, it is critical to compare the costs and performance of different energy storage technologies on an equitable basis.

How to calculate energy storage investment cost?

In this article, the investment cost of an energy storage system that can be put into commercial use is composed of the power component investment cost, energy storage media investment cost, EPC cost, and BOP cost. The cost of the investment is calculated by the following equation: (1) CAPEX = C P × Cap + C E × Cap × Dur + C EPC + C BOP

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

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.

How much do electric energy storage technologies cost?

Here, we construct experience curves to project future prices for 11 electrical energy storage technologies. We find that, regardless of technology, capital costs are on a trajectory towards US$340 ± 60 kWh −1 for installed stationary systems and US$175 ± 25 kWh −1 for battery packs once 1 TWh of capacity is installed for each technology.

How can energy storage technology improve economic performance?

To achieve superior economic performance in monthly or seasonal energy storage scenarios, energy storage technology must overcome its current high application cost. While the technology has shown promise, it requires significant technological breakthroughs or innovative application modes to become economically viable in the near future.
