An optimal power system portfolio for the US state of California that would drive the world’s fifth largest economy towards greenhouse gas reduction goals for 2030 and then to zero carbon by 2040, includes 1GW of long duration energy storage.

Paul Verrill, director of energy data analysis & consultancy firm EnAppSys, explains how renewable energy generation, with the integration of smart grid technologies and efficiency energy storage systems, can create a sustainable power system for the future.

It’s been predicted for some time that the redox flow energy storage space will, after some turmoil and rapid consolidation, find success in providing energy storage at durations of more than four hours. This past couple of weeks have been a tale of both turmoil and success.

The latest auction for the UK’s Capacity Market cleared at a record low price at the end of last week as battery storage projects seemingly struggled to compete.
