Energy storage system cost test

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.

What is the 2020 grid energy storage technologies cost and performance assessment?

Pacific Northwest National Laboratory’s 2020 Grid Energy Storage Technologies Cost and Performance Assessment provides a range of cost estimates for technologies in 2020 and 2030 as well as a framework to help break down different cost categories of energy storage systems.

Are energy storage systems cost estimates accurate?

The cost estimates provided in the report are not intended to be exact numbers but reflect a representative cost based on ranges provided by various sources for the examined technologies. The analysis was done for energy storage systems (ESSs) across various power levels and energy-to-power ratios.

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.

What are energy storage cost metrics?

Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).

What is the cost of a stand-alone energy storage system?

19 The total cost of a stand-alone utility-scale energy storage system with a power rating of P(kW) and storage duration H(hrs) can also be represented using the following linear equation: Total System Cost = $311.28*P + $300.24*P*H with an R squared value of 99.8. 40
