ESS Inc’s recent special purpose acquisition company (SPAC) merger, which listed the iron flow battery manufacturer’s shares and warrants on the New York Stock Exchange, has raised US$246 million cash.

A new CEO-led organisation representing a broad range of long-duration energy storage technologies and their role in achieving global energy system decarbonisation has launched today. 

New York Governor Andrew Cuomo has said the state is “exploring every resource available as a potential tool to address climate change,” as funding was announced for long-duration energy storage technologies along with investigation on the role of green hydrogen in decarbonisation.

Ensuring high quality levels in the manufacturing of lithium-ion batteries is critical to preventing underperformance and even safety risks. Benjamin Sternkopf, Ian Greory and David Prince of PI Berlin examine the prerequisites for finding the ‘sweet spot’ between a battery’s cost, performance and lifetime.

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.

Recent moves in California to develop large-scale energy storage with four hours’ storage duration are just the beginning of a move towards using batteries as a capacity resource, the president of flow battery company CellCube has said.

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.
