WHITE PAPER RESEARCH REPORT Comparing the Costs
factors driving the need for long duration energy storage and the role it plays on the grid. In this second paper, the installation and operating costs of. the five competing long
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.
They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.
Multi-energy storage performance under different scenarios: (a) Lithium iron phosphate battery energy storage, (b) pumped storage, (c) compressed air energy storage, and (d) hydrogen energy storage. The EES for the renewables scenario focuses on the economic indicators of energy storage.
This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
