First, I have to disclose that I work for a company that manufactures hydrogen generators. Virtually all of the equipment we have sold has been for industry or laboratories where the transportation or storage of hydrogen was not desirable. The market determines what works and what does not except for subsidies (ethanol).
Second, hydrogen is NOT an energy source. It is an energy carrier. Hydrogen does not occur in the free state on this planet even though it is the most abundant element. It has to be manufactured and it is expensive to do so. Otherwise we would be using it.
There is little doubt in any logical mind that hydrocarbons are a finite resource. If you have seen the staggering growth in India and China, as I have, it is pretty clear that the future will have another couple of billion people that want the same oil and gas that we want. When you look around and see that the plastics, fabrics, shampoo, fertilizers, and on and on all come from petrochemicals you realize how important the resources are to modern society and how much will change when supplies tighten. It is almost a crime to waste. Future generations will consider it the great folly of our era.
Nuclear. I agree that we will probably be saved by nuclear, hopefully by fusion. I have supplied some equipment for the fusion development project that has (not enough) worldwide funding and is in Europe. What is the solution for transportation? Hydrogen. Either through electrolysis or some other technology. Hydrogen can be a very dense energy carrier. This is why fuel cells are used for space missions because the batteries are too heavy to lift. Electric cars have a short range on batteries and the wires would be a tripping hazard for those of us that still like to walk.
so another solution is required. Hydrogen produced from nuclear power on-site could be the way to extend the range of vehicles. They are even talking seriously about hydrogen fuel for aircraft. This would free up a lot of oil for the petrochemical industry as supplies dwindle.
Nothing will change significantly for perhaps 50 years except for the price of oil. Recent energy policies that have encouraged domestic drilling and extraction have advanced the technology of drilling so future finds are a certainty, but it also means that we will likely be the first major industrial country to run out of oil first. We better be ready. I'll be gone by then but I hope what I am doing today will be part of the solution and not part of the problem.
We will probably see fork trucks start using hydrogen and fuel cells fairly soon. Solves the problem of CO from propane trucks and solves the problem of the long recharge time on electric trucks that take them out of service. The fuel cell stacks are looking much better and I actually think they have a chance. The economics of $4 a gallon gas will change a lot of things in our lives. Innovation can come from the most unexpected places. The president of IBM once said there was a market for for something like 5 computers. That is pretty close to the market for hydrogen cars today. One for each company. When the oil is too precious to use for joyriding, people and markets will be willing to make other choices.

Good Job playing.. nice idea.. someday it may be viable, but not right now..
