Zinc Bromide GEL batteries. Cheaper, greener, simpler & safer than lithium -ion!

Zinc bromide as power storage is quite old, but the gel concept reduces the bromine build up problems. Looks very promising.

I love the way you present new products in an optimistic but sober way without the usual hysterical "gamechanger" hype. Thank you so much for sharing. We are in the midst of a "game changing" energy revolution, but the development is slower and more difficult than many would wish for. However, the real difficulties lie more in the social, political and economic spheres than in the technologies themselves. And while most politicians and economists seem to be STEM and engineering adverse (or at least ignorant of) we will have big hurdles... Enjoy your holiday next week!

This has by far, the best chance of succeeding, especially given it can slot so easily into current manufacturing processes.

I love the idea of new kinds of batteries for different applications. The ground doesn't care how heavy the battery pack is so a lower specific energy isn't that big of a deal. So use Zinc Bromide GEL, LFP, Lithium Ion, Lead Acid, etc...where they are most fit for purpose. :-)

I've felt for some time that Li-Ion batteries are overkill for home/business/utility scale battery systems. With Li-Ion more ideal in the realm of mobile solutions. Stationary batteries do not suffer from the practical limitations inherent in mobile solutions. You don't need something that is particularly light or small. I definitely feel that Li-Ion does not hit the sweet spot for stationary applications. Furthermore it would be better if the demand for minerals needed for Li-Ion for mobile applications does not have competition from the manufacturing of stationary batteries.

Could be really interesting to eventually switch out existing Li-ion batteries for these, in ground-based applications, and repurpose/recycle the lighter weight Li-ion cells for mobile applications

Technology aside, 'Just have a think' always provides an easy listen. The important pros and cons of each technology are covered and explained in a thorough yet simple way. Love this channel.

If this works out, lithium will keep going for a while but it would be goodbye lead acid. And the idea of reusing most of the infrastructure for making LA batteries for the new fangled ones is just excellent! Probably these batteries would be better for ground based energy storage than L batteries too, when weight isn't an issue (if it happens).

This looks very promising and I'm glad to see how close they are to mass production. I would like to see more information on the charge/discharge longevity of such batteries. If there are some critical assessments that would be a helpful addition as well. One thing I'm aware of is that bromine is a highly reactive element which easily diffuses into the air. That is not a situation found in most of the other battery technologies.

Warm greetings from sun-generated electricity from central Poland. Thank you for introduction of this new type of rechargeable batteries.

A very interesting and well presented report on Gelion's battery breakthrough. One thing I found disappointing was the lack of critical specifications such as charge/discharge efficiency and charge/discharge rates,. My interest is for off grid power applications. It wasn't clear how much cell management electronics will be required, either.

Many thanks for this one. This battery was announced at Sydney U with campus lights that solar collected in daytime and lit up at night. It is progress indeed that Gelion has made it onto your illustrious channel. Personally I will be happy when a powerwall replacement becomes affordable - even if I have to put it in a small garden shed.

Year after year, a new revolutionary battery technology is announced, yet year after year we're still using Li-ion.

I'm looking forward to your episode when you will follow up the different kinds of energy storage technologies that you have reviewed earlier.

You went into your 1 week break on a really high note. Loved this one. Positive hopeful video!

The only relevant question for stationnary storage: what's the cost of installed kWh ? How does it compare with, say, Form Energy Iron air battery with presumed 20USD per installed kWh ?

Bromine is classified as an extremely hazardous substance in the United States. I'm not sure how safe this is. It still be practical for grid-scale application where the operator has full accounting, but I can definitely see a NIMBY situation for anyone trying to implement it.

AND, it's nice to have your name to put with your face, Mr. Dave Borlace. Thanks for all you do.

The Gelion battery has been safety-tested by heating on a hot plate to 600 degrees. It can't catch fire. It kept pumping out power until the casing eventually melted and the thing fell apart.... It's very promising for long life, safe grid storage solution. GELN share price is just under 1 GBP and it's significantly under-priced in my opinion. (I've invested)

I have always looked at lithium batteries with the question: "Why are people using those when weight isn't an issue?" Lithium is great for moving objects, but for stationary ones the advantage is small. I've used lead-acid for electric vehicle designs before electric cars were popular, and it worked. But Lithium is great there. And should probably be reserved for that application.
