Lead-acid energy storage cost analysis table

What is a Technology Strategy assessment on lead acid batteries?

This technology strategy assessment on lead acid batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

What are lead-acid rechargeable batteries?

In principle, lead–acid rechargeable batteries are relatively simple energy storage devices based on the lead electrodes that operate in aqueous electrolytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.

Can lead-acid batteries be used in electric grid storage?

Perhaps the best prospect for the unutilized potential of lead–acid batteries is electric grid storage, for which the future market is estimated to be on the order of trillions of dollars.

Which battery energy storage technology has the lowest annualized value?

• On an annualized basis, Li-ion has the lowest total annualized $/kWh value of any of the battery energy storage technologies at $74/kWh, and ultracapacitors offer the lowest annualized $/kW value of the technologies included. An attempt was made to determine the cost breakdown among the various categories for PSH and CAES.

How much does a lead-acid battery cost?

There are not many examples in the literature of O&M costs specific to lead-acid systems. Aquino et al. (2017) estimated that the fixed O&M cost for an advanced lead-acid battery combined with an asymmetric supercapacitor to be in the range of $7-15/kW-year, and that the variable cost for the same system is estimated to be $0.0003/kWh ($0.3/MWh).

Are large lead–acid batteries in operation?

However, large lead–acid batteries with discharge time of hours are in operation, e.g. in Chino project, California, with a power capacity of 10 MW and 4 h discharge time . New advances in lead–acid battery׳s configuration has offered improved characteristic for the utility scale applications.
