What are the disadvantages to alternative fueled vehicles?

-CNG compressor in fueling system is expensive. -Electric- initially more money, batteries are expensive, heavy and don’t last, recharging situations not in place yet. -H 2 / Fuel Cell- manufacturing and operating costs are high, and high quality H 2 is expensive. -Hybrid Gas/ Electric – Still produce some polluting emissions.
