Utility and network needs are rapidly changing and some are adopting both batteries and ultracapacitors to meet these needs. David Lentsch of Maxwell Technologies looks at some of the various approaches.
US-based power firm Duke Energy plans to increase the energy storage capacity of its Bad Creek pumped storage hydroelectric station by 200MW between the years 2021 and 2024.
A large-scale system combining advanced batteries and ultracapacitor energy storage to provide utility grid services is up and running in North Carolina, according to one of the project’s partners.
Reports that a grid operator in France has found battery-based energy storage “too costly” to be used to integrate renewable energy have been criticised by a spokesman for energy storage developer Younicos.
