Assessment of advanced batteries for energy storage applications in deregulated electric utilities. Final report
- Electrochemical Engineering Consultants, Inc., Morgan Hill, CA (United States)
Fourteen advanced battery technologies, including advanced lead-acid batteries, batteries with nickel oxide positives, flow batteries, high temperature batteries, and ambient temperature lithium batteries, have been critically evaluated. Of these, ten technologies were found to be sufficiently promising to warrant a more detailed assessment. This assessment was performed in relation to four model energy storage applications for restructured electric utilities, by making comparisons with baseline lead-acid batteries that could be usable in the four applications. The economic attractiveness of batteries for the four model applications and the potential markets for batteries in these applications were not quantified. In the assessment, three battery technologies were found to be more economically attractive on a cost over life basis, and are expected to have better characteristics, such as lighter weight or better cyclability, than the lead-acid baseline systems. A further four technologies are expected to be somewhat more economically attractive, or economically equivalent and better performing than the lead-acid baseline. Four technologies were found to be potential candidates in the future, meaning there is evidence of economic attractiveness and technical superiority, but that further information is needed before a determination can be made as to just how attractive they might be. A recommendation is made that the possibility of jointly-funded projects to develop the most-promising advanced batteries for restructured utility applications be explored.
