If kept in a vacuum insulated tank (big Thermos bottle), it could last a fairly long time. As the compressed (even liquified at that temp?) air heated slowly it would have to be bled off.

uh, you are joking right? minus 100 degrees centrigrade? can you even comprehend how much energy would be needed AND insulation to keep it at that temperature? Mind you this air is compressed to 4,500 pounds per square inch! So you want to bleed it off as it warms up? Then you might as well keep it hooked up 24/7 to an air compressor that will compress to 4,500 pounds per square inch!!! That is more than the preassure at the bottom of the deepest part of the OCEAN!
