Converting internal combustion engines to run on hydrogen is nothing new. IIRC, GM, working in conjunction with NASA, accomplished this with at least one full-size Chevy and a Monte Carlo back in the early 1970s. Unfortunately, the use of hydrogen as a vehicle fuel never really progressed any further in this country.

That a real shame.

One thing that distinguishes hydrogen from any other fuel that I've heard of is that that it is a perfectly renewable resource. I suspect the most abdundant source of hydrogen would be water, but liberating H2 from O is a slow process.

When it comes to the environment, burned in the presence of oxygen, the only product of combustion is H2O - in the form of water vapor. However, conversions that I've seen use atmospheric oxygen, which is not pure, and I'd have to wonder what other byproducts of combustion might result from that.
