AIR tech.

Compressed air energy storage is coming, but how does it work?

Broken Hill will be the location of Australia's first large-scale compressed air energy storage system. What is it and how does it work?

That is interesting. I just don't understand why they can't run cool air through the turbines and harness the heat created by compression to increase overall efficiency.

Well Scott sign up with them and let them know what ya reckon or at least ask the question.....whoa! There are some experts on here that will answer you lol.

Not an expert but I have supplied thousands of ventilators to cool the turbines and transformers. They work better when they are cooled. Maybe the heat generated is not enough to worry about when they are already generating 7 or 8 MW

I would think that using cooled air would work better also for many reasons. The article however states that the air is cooled before storage, the removed heat is stored, and then the air is reheated before use in the turbines which seems unusual. They also state that they have only reached 60% efficiency and the heat problem has to be responsible for a significant amount of that inefficiency.
