Defense and aerospace giant Lockheed Martin wants to be the first disruptive company of the flow battery era, with the expectation that its first devices will go into series production before the end of this year.

Flow battery maker Avalon has initiated a novel business model aimed at lowering the cost of deployment of its energy storage units, effectively ‘renting’ the electrolytes in the devices to a customer in California.

With a view to creating a mass market design for vanadium flow batteries, Australia’s Protean Energy will deploy a 4MWh battery energy storage project in South Korea that will be researched over eight years of operation.

ESS Inc, US manufacturer of a novel iron flow battery for stationary energy storage applications, has entered the German market via an agreement with investor, chemical company BASF.

One of Germany’s largest utilities wants to build what it says could be the biggest ‘battery’ in the world to date – using underground caverns filled with saltwater as a giant redox flow energy storage system.
