I thought I read somewhere that if all of the current corn acreage was used for fuel, it would only be about 10% of our needs. I think there is a capacity problem that cannot be overcome. That's true and it's driving up the price of beef - at this rate I'll need two or three deer tags. The holy grail is the discovery of an economical process to use the corn stalks instead of the grain - cellulosic ethanol. Now to convince everyone that hydrogen is much safer than gasoline Hydrogen still requires 4 times the space to store the same amount of energy as gasoline - which leads to compression solutions. Not sure I want a 5000 psi 60 gallon gas tank in my car. If you thought the Ford Pinto was a problem...you ain't seen nothing. What I don't know is whether the solutions involving combining hydrogen with other materials to create a solid increase or decrease the volume problem. If you've done any SCUBA diving - you'd know they fill tanks in a bath of water in a safety tank of steel and concrete in case something goes wrong and generally to only 3500 psi - could you see bubba filling his truck with an 88 gallon tank compressed to 5000 psi with no cooling. Perhaps we build containment walls around the filling pump? Also, SCUBA tanks are tested every few years to ensure they can still handle the pressure. I don't think hydrogen is safe in it's normal/compressed state - some other form of storage is required.
