US utility company Alliant Energy has moved forward with a long-duration energy storage project based on carbon dioxide-based technology.

Executives at US flow battery manufacturer ESS Inc. have said the company will be able to continue into 2025 and reach a gigawatt-hour of annual production capacity next year.

A new research centre ‘uniquely equipped’ to evaluate energy storage technologies has opened at Pacific Northwest National Laboratory (PNNL) in Washington, US.

Work has begun on the first pilot project using Form Energy’s iron-air battery, designed to cost-effectively store and discharge energy over multiple days.

A disused paper mill in Maine, US, will host a ‘multi-day’ battery storage system as part of a major project to reinforce and upgrade the electricity grid in New England.

The Central Electricity Authority of India (CEA) is fast-tracking two large-scale pumped hydro energy storage (PHES) projects totalling 2,600MW of power.

SSE Renewables has revealed plans to progress a 1.8GW pumped hydro project at Loch Fearna, Scotland, UK.

The Energy Research and Development Division of the California Energy Commission (CEC) has issued a report highlighting the importance of energy storage facilities with a discharge duration of eight hours or more in order for the Golden State to reach its target of a zero-carbon electricity grid by 2045. 

The CPUC has proposed the procurement of over 10GW of new energy resources, including 1GW of multi-day long-duration energy storage (LDES) and another 1GW of 12-hour-plus LDES.

Rounding up a busy week’s worth of energy storage activity from the UK market, as reported by our colleagues at Solar Power Portal.
