The compressed air for such vehicles might be easily produced by common forms of renewable energy. Using the plastics might permit open source fabrication using numerical control, including additive manufacturing. The energy, vehicles and compressors might be easily produced by decentralized methods, even circular industry. This technology might develop into an inexpensive green transportation technology. Also, the weight and cost of tanks and pneumatic parts might be reduced by using recycled and bio-based thermoplastics. For example, combining the storage tank into the car chassis, higher pressure tanks, new rotary engines, and a more efficient heat exchanger. Efficiency and range might be increased by a number of practical improvements. This is as much as 90% of the efficiency of lithium-ion electric cars. This prototype used low pressure air tanks and exhaust air recovery to power a paraffin heat exchanger system. Reza Alizade Evrin of Ontario Tech University developed an isothermal compressed air vehicle. The capacity factor can reach up to 3.6 MJ/m 3 Isothermal compressed air energy storage ICAES plants can store energy with up to four times the energy per volume (capacity factor) of lithium-ion batteries. Thermal energy losses in the compresser and tankage reduce the capacity factor of compressed air systems. Air cools when expanding and heats when compressed. The car might be powered solely by air, or combined (as in a hybrid electric vehicle) with other fuels such as gasoline, diesel, or an electric plant with regenerative braking.Ĭompressed-air cars utilize a thermodynamic process. It is propelled by the release and expansion of the air within a motor adapted to compressed air. Compressed air system with a PCM heat exchanger prototype diagramĪ compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air.
