Large energy storage pack cost analysis

Can cost and performance analysis support battery energy storage research?

Cost and performance analysis is a powerful tool to support material research for battery energy storage, but it is rarely applied in the field and often misinterpreted. Widespread use of such an analysis at the stage of material discovery would help to focus battery research on practical solutions.

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.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

What are base year costs for utility-scale battery energy storage systems?

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation.

Are stationary energy storage and electric vehicles competitive?

In addition to concerns regarding raw material and infrastructure availability, the levelized cost of stationary energy storage and total cost of ownership of electric vehicles are not yet fully competitive to conventional technologies, mainly due to high battery cost.

How can a battery cost and performance analysis be implemented?

Using publicly available information on material properties and open-source software, we demonstrate how a battery cost and performance analysis could be implemented using typical data from laboratory-scale studies on new energy storage materials.
