Electricity is not the problem if you have a catalyst that will let you do it with a small enough current . So if your catalyst works good enough you can use a cheap pv to get the goods. Actually now a number of new catalyst have been found…take a look at what Dan nocera has been doing at MIT for instance….

We do not have a cost effective way to produce hydrogen from water. We also have no distribution system to get it from producer to vehicle.

Battery chemicals are contained and recycling processes are developed. We are already recycling lithium-ion batteries. “EMF caused cancer” lacks credibility.

Please provide some support for your “Detroit has a deal with the oil companies to make money by using oil.” claim. Sounds like a bunch of conspiracy bunk to me. And flies in the face of the fact that Detroit is starting to go electric.

The oil and battery industries spend tens of millions of dollars per year on disinformation campaigns and fake pundits/shills to discredit hydrogen because it beats their products on every metric.The waste product from hydrogen is potable water, the waste product from oil is cancer. (Oil is the root cause of cancer. ) It is worth anything to end Cancer so any arguement against hydrogen is offset by this fact alone. The waste product from batteries is Lithium poisoning and EMF caused cancer (The GM- EV1 was destroyed because of the EMF cancer risk).Hydrogen can now be efficiently made from water and the competing interests can’t control water so that want H2 stopped.The more batteries you add to an electric car, the less far it goes. Hydrogen carries more energy at less weight than any battery.Detroit has a deal with the oil companies to make money by using oil. Big oil does not want Detroit using H2. Big Oil controls the U.S. DOE and orders them to delay hydrogen.For every negative you could get a shill to make-up about hydrogen, there are thousands of technical papers that disprove it. For every negative that you hear about oil and batteries there are hundreds of thousands of technical papers that prove it.The gulf coast will now experience a doubling of cancer rates within 10 years, essentially killing off the deep south because of the BP Oil spill.Hydrogen runs the sun and that seems to work pretty well.

The production cost for wind-electricity is roughly a nickel now. During off-peak hours wind farms can sell for less than a nickel and make money.

But “$3/gallon” won’t put hydrogen fuel cell vehicles on the road. EVs using average priced ($0.12/kWh) electricity are running on “$1/gallon” juice. Hydrogen will have to get well below “$1/gallon”
to push EVs off the road once we have 200 mile range and an adequate number of rapid charge points.

It’s not the catalyst that makes hydrogen fuel expensive, it’s the electricity. It takes 60 kWh to make a gallon equivalent of hydrogen. At $.10/kWh, that’s $6.00 a gallon.

We won’t see hydrogen fuel until we have electricity at $.05 kWh or less. Solar can’t do that, but maybe some excess wind power (at night) can.

The World needs to begin building a bridge to the Hydrogen Economy, but that will require clean, affordable electricity – something we haven’t found yet. That’s the missing breakthrough, not a better catalyst.

Good Post. Hydrogen is the future energy carrier along with fuel cells.

Do you really think there’s much chance that we’ll ever drive hydrogen-fueled cars?

It looks like we’ll have affordable EVs with very good range (>200 miles), rapid charging (<10 minutes), and rapid charging stations in less than five years.

Hydrogen has three hurdles to overcome – 1) cheap, non-natural gas production, 2) efficient, affordable storage/distribution, and 3) affordable, long-life fuel cells.

Production and non-platinum fuel cells have made progress in the lab, but both are seemingly far from production. What works in the lab does not always transfer to real-world usage.

Distribution would require creating an entirely new infrastructure of hydrogen "gas stations" and delivery trucks. Hydrogen is bulky and hard to contain.

I can see hydrogen becoming a way for us to store energy in order to shift high supply to high demand, but I'm not optimistic about a hydrogen transportation future.

If EVs become accepted as an affordable, convenient form of personal transportation I can't see hydrogen fuel cell vehicles becoming adequately cheaper so that they could gain a meaningful foothold. Where will the demand arise to spend the billions of dollars to create hydrogen fueling stations?
