How does it perform in the rain?

FTFA: Lead researcher Michael J. Aziz said the storage of intermittent forms of renewable energy such as wind or solar power could be more economical if organic flow batteries were used to provide back-up power when the wind stops blowing and the sun isn't shining.

Flow batteries probably won't ever be used for EVs, but great for grid storage.

It's totally against Musk's ideology (Solar Superchargers and all) so definitely *not* in a Tesla product.

2 cups rhubarb, sliced
2/3 cups granulated rhubarb
1 tbsp. all-purpose rhubarb
1 tsp. grated orange rhubarb
3 tbsp. rhubarb, on fire
1 large rhubarb
1 cross borehole electromagnetic imaging rhubarb
2 tbsp. rhubarb juice

Flow batteries were proposed for electric cars as far back  as the 70's.  The idea was that
you would go to the filling/charging station and they would pump out the discharged
electrolyte and refill the battery with recharged solution.  The energy density never
allowed for a small enough battery.  This idea for large scale storage sounds
promising.  But like the other daily alternate energy "breakthroughs", I'll just wait and
see.

No one gets my post.

Now get off my lawn.

I didn't see any mention of energy density.  How big would a battery with, say, 10KWh capacity be?


Unlike solid-electrode batteries, flow batteries are recharged by two chemical components dissolved in fluids that are kept in separate tanks.

Maybe this is a reporter translation error.  Does this imply that the recharging process means physically replacing the fluids rather than plugging into an energy source?

My bike ride across Iowa was powered by strawberry rhubarb pie... and beer

So this isn't a fuel cell how?

Why is that? Too big? Do EVs have anything in thing in the works with higher energy density?

BEV drivers absolutely hate the idea of not being able to recharge at home.  Anything that requires them to "fill up" at a station is an instant non-starter.

Yes, but can the flux capacitor run on garbage?

There's an old phrase - "Do you think the rain will hurt the rhubarb?" to which you would reply "Not if it's in cans."

To my understanding, it was a catchphrase you'd use if you wanted to change the subject if it was unpleasant.

Oh, please. You know better than to complain about being too obscure. In fact, someone just made you look silly a few posts later.

Conventional Lithium batteries and fast enough (and getting faster all the time) that it's not really necessary these days to come up with a "liquid refueling" solution.  The biggest advantages of flow batteries are that they can do endless cycles without degrading, and they are easily scaleable.  That makes them nice for grid storage, where energy density isn't a big deal because it's stationary.

Either, if I recall correctly.  If you need a quick recharge, replace the fluid with fresh stuff.  Otherwise, run them backwards.

Albinoman: So this isn't a fuel cell how?


Pretty similar, but two electrolytes instead of a fuel (usually a gas) and oxygen.

Yeah, energy density is (relatively) low, which is a huge deal with EVs.  Even today's Lithium is much more energy dense, and future technologies such as Lithium-air and Lithium-sulfur batteries will increase that even more.

As an EV driver, I have to agree.  Stopping to fill up is a bug, not a feature.  Even with a relatively low range, I much prefer to drive my EV for this reason.

overall, the concept kinda put me in the mind of it being a hightech potato clock battery.

how am I right/wrong? no snark, actually interested.

I just started the Old World Blues expension in Fallout: New Vegas. I never thought I'd be able to say that I have a Tesla Coil in my head. But now I can, and I feel so cool.
