If you would have read further it will explain the hydrides of hydrogen and it says that a incendiary bullet can be fired through it and the tanks can be cut in half and not lose hydrogen. this is all true and acurate. The only thing I would be worried about is the burning out of the rings. I believe that hydrogen burns at a higher temp than conventional gasoline and will burn out the piston rings. Kind of like running premium gas in an old car. I work on cars on the side of my normal operations as kind of a hobby and relaxation tool from the stress. If you replaced the rings with some of higher quality (made to withstand the high heat) rings as opposed to converting your car with stock piston rings, I don't see why it would not be a great thing to do except the cost. If you do the math, and your car is not made to last over 250,000 miles it is not saving you any money at all.
