 AIRBOOSTER.COM - COMPRESSED AIR SAVINGS
Unfortunately, most compressed air systems are inherently inefficient, converting less that 20% of their energy input into useable compressed air.
Consequently, reducing unnecessary compressed air usage and improving the efficiency of the compressed air systems themselves are excellent energy-saving strategies.
Compressed air is often used because it is believed to be convenient, safe, and labor-saving.

 Treehugger: What About Compressed Air Cars?
The compressed air technology (CAT) engine is used whenever the car needs lots of energy (to start up and accelerate), and the electrical drivetrain is used to maintain velocity and cruise, requiring a lot less power overall than an all-electric cars.
Of course, air cars will only be as clean as the energy source used to compress the air that powers them, but it is a lot easier to clean up that process than to clean up the internal combustion engine.
The air is compressed using a small motor, powered by a 48-volt battery, which powers both the air compressor and the electric motor.

Air in the caverns is pumped up to 1000 pounds per square inch (mean sea level air pressure is 14.7 psi).
When electricity demand is high, air is released from the caverns and used to generate electricity (1).
The released air is heated by natural gas in a combustion chamber and then passes through high-pressure and low-pressure expanders to power a generator, which in turn generates electricity.

 OPTIMIZING PULP & PAPER MILL COMPRESSED AIR SYSTEMS
An investment-grade compressed air audit, analysis, design, and upgrade in an industrial facility requires a thorough understudying of original design basis, current problem definition, goal settings, load assessment, base case model development, and an ability to conduct unlimited "what if" analysis to determine the cost-effective efficiency improvement measures.
As usual, the compressed air utility was expanded on as-needed basis, but without optimizing electrical energy consumption of various compressor units that were partly loaded, under utilized and poorly designed as an integrated utility system.

 Air Hybrid Vehicle Study at UCLA Engineering School   (Site not responding. Last check: 2007-11-06)
Like its cousin the electric hybrid, air hybrid vehicles are being explored as a more fuel-efficient means of traveling the nation's roads, especially in urban areas, where stop-and-go traffic leads to a wasteful use of gas.
To make the air hybrid design work, Tsao introduced a few clever modifications to a traditional 2.5 liter V6 engine, including a valve design that allows the engine to not only burn fuel more efficiently, but to compress and expand air captured during braking as well.
As the car speeds up, the engine is used as an air motor to drive the vehicle until the compressed air is depleted, at which point the engine is switched to conventional combustion mode and begins burning fuel.
