@ Tom the Brat
“Where you gonna get all that hydrogen?”

From WATER…aka H2O 9thatwould be TWO hydrogen atoms for every one oxygen atom).

A fool cell will never be viable for many reasons but the most important is it takes 4x’s as much energy/mile than an EV does. And cost of energy, eff will be the driver of future transport.

Ian is completely wrong as EV’s cost many times less, charge faster, 15 minutes at a fast charge station and can go as far or farther/charge. Now we buy Lithium LiFePo4 EV size batteries for around $.30/wthr which is less than a sealed lead battery.

Everyone else has dropped H2 cars except Honda because the only reason for them was to keep EV’s from becoming common, used as the excuse. But now 300 mile EV’s are viable as Li batts drop in price they can’t be ignored anymore since oil is going back up with a bullet.

As for them being coal powered, coal is dying, being replaced by NG. Last yr wind was the largest new electric energy source, beating coal, NG, nuke, hydro. But even powered by coal EV’s according to the EPA are cleaner, more eff. Many Evers buy RE to charge their rides.

My EV’s get between 250 and 600mpg cost equivalent at $2.50/gal gas. Let’s see HS or any other type beat that!! And using wind or solar I can make my own fuel if prices rise.

It is true that hydrogen is the best performing fuel in Fuel Cells. It needs less noble catalysts (platinum) and provides high power density and acceptable cell-lifetime . Hydrogen is, however, a highly explosive gas and compression, storage and transport, also liquified or stored in metalhydrides, is quite expensive and needs severe safety precautions. A distribution grid typically in a major European country will cost approx. 2 Bio. Euros which the consumer has to pay through the Hydrogen fuel price.
Because of these barriers liquid fuels like Methanol/Aethanol, that perform at lower power density are nevertheless preferred since they can take advantage of the existing distribution grids and the storage on the vehicles is much easier and less costly than for a highly explosive gas.

Hydrogen is not a “middle man,” it’s a longer solution for electrics. Stop thinking of hydrogen as a “fuel” and instead think of it as an electric storage medium, which is what a fuel cell really is. Pound-for-pound, inch-for-inch, compressed hydrogen WAY outperforms any battery technology. It’s also fully renewable and non-polluting.

Toyota is reading the tea leaves and foreseeing the quick death for the carbon based economy. With global action now revving up to cap or make costly carbon fuel sources like coal and oil, alt fuels are going to start moving forward quickly. Electric vehicles are basically coal (or worse, nuke) powered vehicles today.

Hydrogen could be a good replacement for baseload power sources, if they can get the funding to work the kinks out. It promises to be a true universal fuel that can power both home and vehicle from distributed power sources, like a home hydrogen power plant.

I hope you can go really far on hydrogen, because I’ve never seen a hydrogen filling station, and it doesn’t seem like they are working on developing the infrastructure by 2015.
