More nonsense: Hydrogen for an alternate energy source

Since some have complained about my nonsense, I'm going to complain about someone else's nonsense to show that I can and do evaluate the OPPOSITE side of the argument before I make a judgment. So I'm going to attempt to advocate FOR something I don't believe to show just how much my convictions are really 'nonsense.'

Hydrogen fuel cells for automobiles:

This is a potentially everlasting fuel source for automobiles, but it depends upon another energy source to be produced. Nuclear, coal, wind, solar... all could be used for vehicles using hydrogen as a catalyst. Electricity is dependent upon either expensive batteries, or upon a physical connection to a power grid. In addition is that batteries take a long time to charge, but gasoline and liquid hydrogen take only about 5 minutes to replenish.

No emissions other than water vapor:

There are actually emissions that come from this fuel, but they originate from locations other than where the cars operate. A nuclear plant can be built in a public location, but coal could be 1000 miles away and the electricity could be transmitted via power lines. Hydrogen fuel is produced using that electricity and then transported via pipeline to fuel station. Cars powered by gasoline produce emissions on sight where hydrogen's emissions can be placed elsewhere.

Gasoline is only 30% efficient:

Internal combustion engines are only 30% efficient and can't be pushed passed that rating, so even with the loss of energy through hydrolysis, the larger the scale of the power plant, the more efficient it becomes.

Storage:

Electricity can't be stored on a large scale, so any excess energy produced from the US power grid is wasted. Hydrogen could take the excess energy and be used where that energy would otherwise be wasted. Batteries are expensive for electric cars, but hydrogen is dependent upon the size of the tanks. That is cheaper than with more batteries.

Universal:

The US has enough coal to last hundreds of years, but most American vehicles can't use anything that doesn't come from petroleum. This would allow for almost any form of energy to be interchangeable to be used for transportation.


So, how many people think this is nonsense?
