This is interesting tech..organic flow battery

The research paper is available for anyone to decipher and it reads well.
I'm no chemist but this stuff is riveting. Would love to see this progress to the point where the tech savvy can build it.
Talk about disruption to power companies..lol

organic flow battery

So the new bit is the "organic" part.
ZBB Energy are around the corner and have been making flow batteries for some time.
I do remember Murdoch Uni had a ZBB flow cell in one of their Golf Club cars they run around the campus.

So the bit about having "minimal impact on the environment" is no better.
And comparing a flow cell to Lithium Ion is pointless as no-one uses Lithium-Ion for backup storage.
It should have been compared to Lead acid as that is more common or LiFePO4.
More recently Lithium Titanate is better for Backup 16,000 cycles vs a flow cell of 5,000 cycles...

I found in the past flow cells aren't particularly good for ev's as they have low peak power.
The advantage is that rather than recharge on board the fluids could be replaced like at a petrol station.
So the short answer is NO but the long answer is YES.

Right..nice link.. I hadn't heard of ZBB.

In reading more, this paper/research was sponsored by ARPA-Energy.. the US Govt Advanced Research... so really deep pockets delving into storage solutions for wind and solar, so I'm guessing system weight and single-cell power output aren't supposed to be a factor... and therefore use inside an EV, and not to mention Cost.....


I would however 'd be very interested to see if this tech can be DIY friendly for home storage of solar power. It'd be great to stash away some of that plentiful sunshine us Aussies are blessed/cursed with, especially if the limit to energy storage is just another couple of 44 gallon drums..
