The tanks must be designed to safety standards appropriate for a pressure vessel, such as ISO 11439. [7]The pressure vessels or air storage tanks that can be used in compressed-air vehicles can be made of low pressure (9 atm (130 psi)) or high pressure (more than 240 atm (3,500 psi)), and can be made of composite materials like thermoplastic and fiber reinforced thermoplastics, [6] [8] that ...

Electric cars were limited to urban use by their slow speed (no more than 24–32 km/h or 15–20 mph [42]) and low range (50–65 km or 30–40 miles [42]), and gasoline cars were now able to travel farther and faster than equivalent electrics. Gasoline cars also overcame much of their negatives compared to electrics, in several areas.
