Back to Hydrogen. From what I understand, Hydrogen powered cars, share a similar problem with electric cars. The problem is range. For Example: BMW has a Hydrogen powered 750. The car has a range of about 250 miles from a 37 gallon tank (about 6.7mi per gallon). It gets worse...The 37 gallons are LIQUID HYDROGEN! Is the efficiency of a fuel cell that much better than an internal combustion engine...I don't know. Is it possible to store more BTUs of hydrogen than liquid hydrogen (other than tied to carbon atoms)? I'm not positive...I hope so
