1 gal liquid H2 weighs approximately 0.25 kg which is 2.7 imes more powerful (energy content) than the gasoline at the same weight. So we are talking roughly 0.675 kg gasoline=1.45 lb=-.9 literl gasoline=0.23 gal gasoline

The fuel efficiency of hydrogen vehicles is typically measured in miles per kilogram (mpgge - miles per gallon gasoline equivalent) instead of miles per gallon (mpg). On average, a hydrogen fuel cell vehicle can achieve around 60-70 mpgge, depending on the efficiency of the specific vehicle and driving conditions.
If you drive 480 miles, and you get 15 miles per gallon, this equals 32. If each gallon is $3.75 per gallon, times 32, this would equal $120 in gas money.
900 miles / 50 miles/gallon = 18 gallons
That is 26 miles per gallon.
At $2 a gallon, about $90.

(835 miles) x (1 gallon/20 miles) x (3.75 bux/gallon) = $ 156.56
You can drive up to 300 miles at that rate.
$128.53
(2,700 miles) x (1 gallon/12 miles) x (2.70 $/gallon) = $607.50
