What is the cost of hydrogen? I found this web site above that tried to make it look like hydrogen was a cheap fuel source. But looking at the numbers I did notice that they were only using $0.03 per Kwh of electricity. I did some checking and found that southern California off peak residential rate is $0.11 per Kwh. I imagine there is some power company that is charging this low of a rate some place, but not in California. This means to get this cost savings they would need to produce only during off peak times. This would limit the amount of hydrogen that can be produce from water. They used the number of 60 Kwh to produce the equivalent energy to one gallon of gasoline. How far does your EV go on 60 Kwh of electricity? One gallon of gasoline has the equivalent energy of 33.7 Kwh. The Honda FCX Clarity can travel 60 miles on 1 Kilogram of hydrogen. 1 Kilogram of hydrogen has the energy density of 33.3 Kwh. Most electric vehicles have over 100 MPGe ratings. We can see that the battery is more efficient over the fuel cell. Using an electrolyzer to extract hydrogen from water is less efficient then charging a battery. This is why an electric vehicle will go 2 to 3 times further on the same amount of energy. The fact is the cheapest source for hydrogen is from waste gasses from manufacturing and land fill gasses. You can also get hydrogen from natural gas. Which is cheap right now.
The Honda FCX Clarity uses a 5000 PSI hydrogen tank.
