I KNOW THAT IS HARD AND EXPENSIVE TO GET LIQUID HYDROGEN BUT I WANT TO KNOW THE PRICE

Answer 1

Why buy it when your car can produce it for free?

I have two tanks installed now. Eight more should give me free fuel.

Answer 2

Liquid hydrogen ranges in prices depending on how it is made, who makes it, and how much you buy.  Typical present costs seem to be around $5.50 per kg.  The density of LH is 0.07 kg/L, so this would be about $0.40 per litre, or about $1.50 per gallon.  It really isn't all that hard to get LH, if you are willing to buy 200 L at a time.

However, if used as a fuel, that gallon of LH has one fourth the energy of a gallon of gasoline.  The ultimate cost would then be $6.00 per gallon.

And some other points to consider.  $5.50 per kg is the cost if hydrogen is made from natural gas.  If made from electricity, it jumps to about $7.50 per kg.  Almost no supplier makes hydrogen from electricity.  The price of natural gas also goes up with the price of oil and gasoline.
