"Apex will need a small amount of natural gas to heat the air it compresses to maximize turbine output."
As far as I understand they need to heat up the turbine as air (a gas) cools down upon (adiabatic) expansion.
And while accumulating / compressing air in ground lacunae, pumping it into the storage, we are just heating up the ground.
Am I right in my understanding of the process thermodynamic ?
- rdiddly 9y agoSounds correct to me. It sounds like they're hoping the compressive heating effects will be dispersed through a large enough volume to be negligible. Whereas the expansive cooling will be concentrated at the point of exit.

- samcheng 9y agoYou are correct, the article has a typo and should state 'decompresses' instead of 'compresses.'
