They had a nitrogen powered car in an article I read a while back. There are some real thermodynamic losses faced with compressed gases. That's why you compress them in water baths - lots of waste heat. Most designs have heat exchangers with the environment on the return cycle to input the lost heat back as it expands, so it ends up not being real bad as long as you don't try to get it all back at once. Considering what high pressure cylinders do when they get uncorked, that's probably a good thing!
