Sounds good, but that makes me ask, so why aren't they already widely deployed? Makes me think there is some problem you aren't mentioning.

- ethbro 9y agoPer Wikipedia, flow batteries aren't as far along the research-production timeline as Lithium batteries. That + grid-scale customers being extremely conservative = gradual uptake.
- Brajeshwar 9y agoActually, there are indeed at-least 5 big and established companies with finished products operating right now. I was talking to a cousin at the World Bank and got connected to a battery expert at the IFC. He calms me down that Vanadium Redox batteries are well proven and are being used now. Improvements are being advanced and announced regularly. In the next few years, I believe this will become common terms, as another means of storage. Some of the "problems" are huge initial capital investment required to start up, the battery sizes start as big as (approx) 5x5x5 ft to get a 5kW output. The recent bad news in the Vanadium Redox Battery is that of Imergy Energy shutting down[1] and their assets liquidated (I read somewhere, Sherwood Partners managed their liquidation). For those interested, IFC recently released a 50+ paged Report on Energy Storage[2]. 1. https://www.greentechmedia.com/articles/read/flow-battery-aspirant-imergy-has-let-go-its-staff-and-is-selling-its-assets https://www.greentechmedia.com/articles/read/flow-battery-as... 2. https://www.ifc.org/wps/wcm/connect/ed6f9f7f-f197-4915-8ab6-56b92d50865d/7151-IFC-EnergyStorage-report.pdf?MOD=AJPERES https://www.ifc.org/wps/wcm/connect/ed6f9f7f-f197-4915-8ab6-...
