@xringer air storage need not operate at 4000 psi to be safe and inexpensive the systems we used in the navy operated at 1850psi, but i would opt for a much lower pressure perhaps 300psi or less and use more of the cheaper and easer to obtain tanks,therby greatly increasing cost and safety concerns.
another very important factor is when trying to charge batteries look at how much storage potential is COMPLETELY lost because the turbine is not spinning fast enough to produce the voltage needed to charge the batteries--air compressor pumps at all speeds and if the turbine spins too fast and produces
extra voltage a portion of extra power is lost there to as well unless your using mppt. See you have to take into account ALL or the real world factors.
@xinger 3rd you don't understand the compressor gives up all it's heat and whatever drives the compressor is what gets hot (motor) but the work done in the compressor and in the pneumatic motor loses all its heat and creates a cooling effect, anyone who has used a pneumatic tool for a long Time knows how cold it gets. On the obverse if you drive the same system from the other side and use a hydraulic motor, you get alot of heat; collect and use that in winter, drive it from air side in summer.
@Xringer I was on an aircraft carrier in the navy and this is the setup we had. Compressed air storage to supply backup power to the hydraulic system via accumulators. I know my diagram leaves alot to the imagination but i'm very busy with other projects now. 1st show me a battery that can retain ALL of its stored power. 2nd you say tanks aren't cheap but show me a battery bank that cost less and will outlast AND outperform an accumulator tank, theyve been in service for many years in the navy
@windsunvolts Show me an air powered car that has 50% the range of a modern EV...
I know you get loads of waste heat off the compressor, (as you burn up KWh) to fill the tanks, but if it's mid summer, what are you going to do with that excess heat? Save it until winter??
An, there is the problem of tanks.. 4,000 PSI tanks aren't cheap.. And, they can be a bit dangerous..
google the Iowa stored energy park for related info on storing compressed air from wind turbines.

@xringer cars have limited space on 10 acres thats that would be a ridiculous comparison as space is a non issue.

Sounds a it would be more, than just a little inefficient.

@Xringer batteries are inefficient.
