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.
For brick-based storage systems, cost and performance information was obtained for a single power output (10 MW) with two different energy outputs (40 and 2,40 MWh) (Terruzzin, 2021). From this information, costs were extrapolated for the various energy and power levels considered in this study by solving two linear equations.
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).
Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.
The total investment cost consists of the EPC cost, EPC contracting fees and owner's costs. For conventional power plants, EPC costs include mechanical system costs, electric system costs, civil costs, and indirect costs.
Energy storage and its impact on the grid and transportation sectors have expanded globally in recent years as storage costs continue to fall and new opportunities are defined across a variety of industry sectors and applications.
