How did Recology's hydrogen fuel cell truck pilot go?

6. It's the tank needed to hold enough H2 for a decent range that is heavy.

At 700 bar (~10,000 psi) a storage system would have a volume of about 200 liters ((53 gallons -progree)) or 3-4 times the volume of gasoline tanks typically found in cars today. A key challenge, therefore, is how to store sufficient quantities of hydrogen onboard without sacrificing passenger and cargo space.

But for a 300 mile range, the H2 itself is lighter than the gasoline itself (progreerian words and progreerian math) :

The compressed H2 itself weighs about 5kg (from the energy.gov source above)

A gallon of gasoline weighs about 6 pounds - jdpower. So at say 40 mpg, a 300 mile range vehicle needs 7.5 gallons or 45 pounds ((20.45 kg)) of gasoline. ((2.2 pounds per kg)).

So the weight difference is that H2 is 20.45 - 5 = 15.45 kg lighter ((34 pounds)) than gasoline.

Caution: the above numbers are typical of a regular vehicle, not a waste hauling truck. It's just an example.
