Anyone hear about this? Another interesting large scale ESS technology - https://www.thecooldown.com/green-t...orage-project-wisconsin-carbon-dioxide-grant/

There have been several studies and attempts to get funding for such a project in northwest Alabama 10-12 years ago by TVA, never got off the ground.
$30million is a drop in the bucket, it’ll all get eaten up. There is a lot of money to be made in the business of studying and scoping such projects- that amount of $ won’t even get a single physical piece of work done

The uncompressed co2 balloon has modern gasworks vibes. I wonder what the lifespan is on that oil made landfill fodder.

Whatever you did, that's what you planned.
Compressed carbon dioxide for long term energy storage. Sounds like an made up idea coupling of today's hot buttons just get to some grant money.

It’s technically feasible. But the idea, which I don’t ever see making economic sense is to capture CO2 from plants burning coal or gas and store it underground in a manner similar to how natural gas has been stored in places like West Virginia for many decades. The next step would be to compress it, then release in periods of high electrical demand, then store and recompress at times of low demand.
The article refers to a 75% efficiency, which is ludicrous and very misleading. They are misleading by giving the efficiency of a small piece of the total process needed to produce the power. If 75% were possible, there wouldn’t be a single coal, gas or nuclear plant left.
