The International Flow Battery Forum is taking place this week and long-time organiser, Anthony Price of consultancy Swanbarton, wrote to Energy-Storage.news with some of his views on the market and a snapshot of where development currently lies.

VRB Energy, a maker of flow batteries headquartered in Canada and owned by a metal resources and mining company, said the first phase of a 40MWh flow battery project in China has now been commissioned.

Vanadium redox flow battery maker VRB Energy has begun commissioning a 3MW / 12MWh energy storage system project in Hubei, China, which is expected to help serve as a demonstrator for much larger projects to come.

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the first of a two-part special report, Andy Colthorpe learns what the flow battery industry faces in the fight for commercialisation.
