A good technology for large scale load matching for utilities and other large industries?

These flow batteries seem a blend of fuel cell and standard storage battery. The constant replenishment of electolyte is like an electron fuel supply line. Do you know why TVA cancelled its big flow battery demonstration project in the deep south?

Thanks for these posts on flow batteries, Jim. I've been meaning to write one myself but you've saved me the time.

Flow batteries strike me as probably the most promising option for load leveling of intermittent energy sources like wind (geographically independent option that is, CAES is great but only when you've got the right geology). Their scalability (in both MW and MWh) is excellent and they offer much better overall efficiencies than producing hydrogen for storage and eventual conversion back to electricity via fuel cells (another fully scalable option).

I imagine 500 MW wind farms with MW-scale flow batteries to avoid the fees imposed by transmission operators for variable energy sources or even to allow the wind farms to operate as 'constant' power sources on hourly timescales.

Doing the math on the economics (i.e. profitability) of such a set-up is a complicated task but I would highly suggest that wind developers start crunching the numbers. I imagine it would pay off nicely at some scale or another...

Can you please acknowledge the source of the diagram of the flow battery you used in your article.
Please note also that the MPower company has ben incorporated into The Axeon company and the new email and web addresses are given above

The leading provider of energy storage technology ZBB is set to go public this month, and many of my friends are eager to get in on the action as it is posed to skyrocket upon opening…Can anyone provide suggestions or feedback on the ZBB play?

Thanks much, DG

Now we just need to find a source of a few extra million tonnes of vanadium each year. Mine the moon, or some asteroids?
