Re: Gravity Energy Storage

This showed up to me today, please forgive if it is redundant:

What I think is also quite interesting is that I have seen ideas of pressuring natural Gas into such wells, as an energy storage method, and then I have to wonder if you could fetch heat up from a well, by pulling the compressed gas up.  In that case you might compress CO2 instead.

Here is a compressed Natural Gas notion: https://www.nrel.gov/news/features/2022 … %20storage.

This might still let you use the suspended weight, provided that there is enough clearance for the gas to be compressed into the well.

As for brining up heat, I guess that might be workable, but maybe not massively impressive in thermal output.  But you would heat the well when you compressed the Natural Gas into it.

If you wanted to live dangerous you could heat the Natural Gas before compressing it into the well.

But if you went to CO2, you could also heat that prior to compressing.

But if you discharged the CO2 the greens would go nuts.  But at least you have used the CO2 created by burning something to do something "Green".

But the weight energy storage concept is very interesting to me.

Re: Gravity Energy Storage

An idea has come to me, which is a combination of Gravity, Compressed Air, and Geothermal/Geostorage.

I am thinking of a variation on the Eavor Company Geothermal: https://www.eavor.com/

Keep in mind that this is more of an energy storage device, then geothermal, but still in some cases geothermal could be involved.

A back and forth cycling of A<>B, allows storage of energy by gravitation, pressurization, and thermal means. 
For instance, when B was pressurized with air, then the heat of compression then is pushed into the well walls.
When it becomes time to release the pressurized air from B though a turbine, then A fill push the air, and the walls of the well section B will distribute heat back into the depressurizing air.

And if you had liked to you could have preheated the air that was to be compressed into B, so injecting extra heat into the well.

But you could also involve true geothermal if the site favored it.

Compressing air into a well, if you encountered Hydrocarbons or Hydrogen could be a bad thing.  But if you encounter hydrocarbons and especially Hydrogen, then that is to be a good thing.

In creating such wells, you might accidently find Helium: https://www.naco.org/news/helium-find-c … extraction.  (They were looking for an ore).

But by drilling wells for energy storage, and perhaps geothermal, you might find a gas resource such as Helium or Native Hydrogen.

In that case you probably use it for that then and try somewhere else.

The storage device could be good for wind and solar energy.
