Deeya seem to be unspecific about what technology they are using for their flow batteries - zinc, vanadium, whatever.
Googling didn't help.

My main interest in the article was mainly in the chemistry involved.
Their initial order seems a better bet for generating revenue to support progress than say VRB who are exploring a market which does not yet exist.

Deeya’s also claims its products will for the first time ever commercialize peak-off-peak load shifting, a market estimated to be worth $10B for electricity consumers and worth $160B for electricity producers and distributors.

I think that the above claim is incorrect. NGK Insulators NAS battery is a commercial product which is already being used for load shifting. I do not think that these batteries are particularly cheap or that the sales volumes are high, but NGK is selling them for profit and not just setting up demonstration projects like VRB.

Roger,

And it is claimed that the worlds largest flow battery is in Fairbanks Alaska, allegedly the size of a football field. There are at least of couple of other companies with various types of flow batteries in the market.

Tom,

Do you have any company names? I know a number of flow battery systems have been installed, but that is not the same thing as having a commerical product available. VRB is still doing demos. Regenysis went belly up, etc. Looking at the ESA website the only comany I found that seems to have a real commercial flow battery product (i.e. they have a phone number you can call to order one) was Premium Power. They are selling a relatively small Zinz Bromide battery for UPS systems.

Roger,
I tried to link a pdf in, but firefox went weird on me. The university is testing a vrb flow battery. I assume it is climate related (Fairbanks is the coldest non Russian city of any size in the world).

yahoo search under "flow battery fairbanks" had several hits.

Roger Brown

Tom,

I found a story related to Fairbanks flow battery. This is a system from VRB Power which is still installing pre-commercial demos. I certainly hope that they eventually enter commercial production, but their web site gives no indication of how soon they hope to do so.

Does anyone know why the CEO at Deeya resigned after being on board only for a few months?

John Roberts

Deeya CEO Vic Mahadevan calls it quits after being on the job for only less than 4 months. The company has been looking for a CFO for 4 months, and now the CEO leaves. Way to go!

Touissant

Please confirm if the Vic Mahadevan really quit...thank you

Adam Whitehead

Another company with a commercial flow battery product is Cellstrom GmbH (http://www.cellstrom.com)

There is no doubt about it. Energy drinks have soared in popularity all across the globe. Since the first of these drink first hit the market, the choices have grown

I wasn't familiar with flow batteries, glad I read this!

Deeya sounds like a pretty good company.

Have they expanded like they planned on doing?

Rug Cleaning Los Angeles

They must be doing an alright job if they raised that much money...or they just have rich investors.

Tours in Venice

Is it weird that Deeya hasn't revealed the chemistry of its' flow battery? Or do you think they're just trying to keep
their secrets so no one steals their methods?

Would you say Deeya is better than the Canadian company?

Furniture Stores in Los Angeles

I haven't heard of Deeya before
