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.

Germany company Voltstorage, claiming to be the only developer and maker of home solar energy storage systems using vanadium flow batteries, raised €6 million (US$7.1 million) in July.

Lithium battery cells will be rolling off a production line at a 16GWh-capacity factory in France in 2023, with manufacturing startup Verkor then planning to scale up to 50GWh “in line with market dynamics”.

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.

Northvolt has now raised over US$3 billion to support its plans to become a major player in the European battery manufacturing space, including US$1.6 billion in debt financing which it announced today.

Iberdrola is to develop a landmark solar-storage-hydrogen facility in central Spain, professing it to be the largest industrial green hydrogen facility in Europe once complete.

While we do acknowledge the challenges faced as a result of COVID-19, we cannot afford to lose sight of the opportunity renewable energy and energy storage solutions, such as the Vanadium Redox Flow Battery (VRFB) present, argues Paul Vollant, Director of Sales and Trading at vanadium supplier Largo Resources.

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.
