in simple terms, the cost of hydrogen and methanol fuel cell systems are a joke...the cost is 8 to 9 dollars per shift. This is contrast to 1.90 to 2.35 for electrical costs for charging, and remember in food distribution, almost all class 3 trucks go into cold.. that's the area where fuel cells have issues with water vapor exhaust....the fuel cell only have been in use with class 3 trucks.. limited in class 1 and 2 due to the enclosed compartment and the need for counterweight.. when companies have the onboard systems.. they lose weight and ampacity to work...in simple words..AC Power has made them a joke...
