There’s a race to develop new technologies – and adapt existing ones – that can either be complementary to lithium batteries, or even compete with them. Representatives from three technology providers offer up some case studies, data, insights and opinions on where they think the market could go.

Independent power producer EDF Renewables North America has signed a 22-year power purchase agreement with NV Energy for a 200MWac solar project coupled with a 180MW, four-hour battery storage system.

US developer and utility NextEra Energy has said there is currently a “terrific opportunity” for wind, solar and battery storage while Texas-based CPS Energy plans to add up to 900MW of solar, 50MW of battery storage and 500MW of new technology solutions to its portfolio.

Long duration energy storage is “essential” to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, who moderates this panel discussion with Matt Harper from flow battery provider Invinity Energy Systems and Russ Weed from gravity energy storage company ARES.

Based in the United Arab Emirates (UAE), Dr Imran Syed is head of industrial power for Enerwhere, designing and implementing hybrid systems that use energy storage. Dr Syed spoke to Andy Colthorpe about some recent project case studies.
