Lithium leader S Korea funds 4MWh vanadium trial that targets doubled energy density
Date: Sep 25, 2018
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.
The ASX-listed company is involved both with vanadium resources as well as creating energy storage systems using vanadium pentoxide electrolyte, producing its own stack technology, V-KOR. V-KOR ‘stacks’ individual vanadium redox flow battery (VRFB) cells within a main system stack, unlike most vanadium flow battery designs in which the whole system is one large ‘cell’. Protean claims this lowers manufacturing costs and improves battery performance. The company connected its first project to the grid in Australia in August, a 100kWh system in Western Australia.
