Compressed Air as Alternative Fuel Source

Share this article:

Compressed air refers to air that’s kept at a prescribed pressure. The air pressure is usually more than atmospheric pressure. Compressed air has many uses, and has actually been utilized for some time now.

Uses of compressed air

Compressed air has been used for several purposes. The most popularly known is its use in scuba diving. The air tank used by divers contains air that’s compressed at 14.7 Psi for every ten meters. Compressed air is also used in pneumatics, or the process of using pressurized gases for work. Vehicles have also used compressed air in their braking systems.

Of late, progress is being made in the use of compressed air to power engines. These engines have been called Air Engines, and use compressed air as fuel. They are practically emission free and cost less than petroleum and hydrogen fuel. An Air Car has been developed to run at over 35 mph, powered by air alone. A company has targeted to release an Air Car that can reach up to 96 mph by 2010.

Advantages of using compressed air as fuel

Compressed air is inexpensive, and can be available anywhere. It is a clean energy source and the technology for this is very simple. It’s always been around but has not been harnessed as alternative fuel until recently.

Compressed air fuel is also chemical-free. Hence, air motor parts can theoretically last a long time. Likewise, ideally, users can “refuel” right in their homes.

Disadvantages of using compressed air as fuel

Currently, compressed air has not been listed as alternative energy sources, alongside hydrogen, electricity and biodiesel. Likewise, their effectiveness varies according to temperature, engine size and tank volume.
