You should be careful listening to anyone, including this channel. Everyone has their own biases and this channel is no different, he is always desperate to pump up any "green" technology and ignores the downsides of the things he discusses, here for example the reality is redux flow batteries are very low density storage systems. It is completely impractical to use these for most use cases as you would need very large amounts of land to store the energy of a large industrial lithium ion battery. This channel always seems to ignore the clear downsides of the technology he discusses if it favours an advertised green solution.

@davestagner

7 ай бұрын

@@paulosullivan3472 Low density storage is only a problem if physical space is at a premium, i.e. on board a vehicle. But for grid scale storage, the usual constraints are cost and lifespan, not size. Lithium batteries are expensive, and have a relatively low ceiling on the number of charging cycles they can handle. Flow batteries can be made of much cheaper materials (like iron and salt!), and can avoid the dendrite problem that eventually kills lithium. This makes it cheaper. If the grid battery farm needs another acre or two of land, that’s ok, if it means saving millions of dollars in the process. Make sure you’re looking at the correct constraints.

Your higher level of sass in this video is sparking joy.

A German company is advertising a flow battery that can be installed at home like a powerwall: "Prolux Solutions says that all components can be repaired indefinitely. It notes that the vanadium electrolyte also retains at least 95% of its capacity, even after 20 years, so it can be reused indefinitely." I live off grid full time and now use LIFEPO4 but I like the idea of a battery that can be fully repaired and doesn't require Lithium mining and can be fully recycled.

Dave, I appreciate your videos! It is my opinion, based on my own energy needs, doing a lot of reading, watching everything on batteries and renewable energy, etc., that batteries are the key to everything! We need less expensive, home and business scale storage batteries. And these batteries need to be inexpensive, safe, affordable, easily recyclable, low cost, made of common materials, and economical. We also need more streamlined permitting and easier access to financing for small scale solar, wind and batteries. Citizens have been mistreated by the utility monopolies for far too long. Distributed energy production and storage is robust.

He fell victim to some anti-nuclear fusion hype, that weird fear-inducing intro he has in his video about nuclear fusion is very inappropriate.

First to demonstrate the vanadium battery was of course Maria Kazacas of NSW University Australia. I thought it was a great idea . Naturally what came to mind then was other elements to use with multiple valence states to exploit , elements like iron yes , then there's copper too but iron is more appealing. Lead also has multiple valence states and the lead acid battery operates because of this . The advantage is when you can avoid the clutter and unpredictability of how heaps of different substances will adversely interact and shorten life . There's heaps of different substances in the lithium batteries as an example. .

People can be terrible, especially online. I appreciate the work you do! On the topic itself, 5c/kWh LCOS with the specs stated (including non-toxicity) sounds pretty dang good. It would be on a level where I think it is cheaper than many of the non-renewables we are using today. So this really sounds promising as a grid-scale energy storage that could help to make a big push towards sustainable electricity production.

Hey dude glad you got to ESS because these companies that are finding solutions without using more expensive elements or rare earth are critical to sustainable grid storage, which is critical for green energy, so I put them high up on the list of great solutions and am hoping they start winning lots of contracts to get their tech out there.
