The power of Hydrogen is very green and useful. It is already used to power some cars. Using hydrogen instead of fossil fuels will reduce our carbon footprint, get out of our dependency on oil and reduce global warming. The only output of hydrogen is water. This technology can power your car and maybe your house. Unlike nuclear fission, it has no harmful emmisions. You can use it in a fuel cell (safe) or maybe liquid hydrogen as to fuel engines for a thought. Even cold fusion can be an alternative to nuclear fission. Hydrogen has given light and energy to our sun and ultimately to Earth and mother nature. It's time to learn from them.
Silly. Hydrogen is not a power source, just a storage medium. There is no hydrogen capture... it has to be manufactured, usually by splitting water using electricity. It is far more efficient to just use the electricity in an electric motor than to create / transport / store hydrogen and create a whole new distribution network and on and on.

Yes we have the conundrum of how we can get the hydrogen, the transportation, the parts of the cell, the labor hopefully with little or no emission. Sort of a paradox isn't it? Can't get the technology of green energy without using an un-green energy source to make the green energy possible, but we can try I guess. :)

Yes, Hydrogen can be explosive. But even gasoline has been known to be explosive but in fuel cells they do not use an engine so no explosives there. And even in an engine with hydrogen the engine can take the pressure (Although the use NASA does with liquid Hydrogen AND liquid Oxygen in large quantities it can be a problem), plus if the hydrogen leaks somehow it disperses quickly because it is a VERY LIGHT GAS (emphasize on light). Even if it ignites it will just pop. Look it up. No burn. You may see the Hindenburg and say hydrogen is bad, but the danger was the hydrogen mixing with the metal on the blimp. There was a mythbusters episode on this, look that up too. And the use I'm talking about is in small amounts (no rocket ship here) and mainly in gas form. There were more explosions of gasoline than hydrogen.
PS - Hydrogen has a specific energy (MegaJoule per kilogram) of 143 in all forms and a energy density (MegaJoule per litre) of up to 10.1 in liquid, and 0.01079 in gas form. For gasoline the specific energy is 53.6 and the energy density is 34.2. Gasoline is more explosive and less powerful. HYDROGEN FTW!

Hydrogen is great until it blows you up. Then the lawsuits start flying and Hydrogen will fizzle and die just like the in the past use of Hydrogen for transportation.
Yes hydrogen has potential, but may be out of scope with what the city alone can do. It takes an entirely supply chain / much more r+d / and mass acceptance for it to real work as a replacement for fossil fuels. Currently the most cost effective way of supplying hydrogen also happens to be extracting it from crude oil.... Worth a thought though.

Fuel cells powered by hydrogen are gaining footholds in certain markets. They are great in terms of zero emissions, so long as the hydgrogen is manufactured/sourced using zero or very low emission methods. At the moment, the only "clean" sources of hydrogen are coming from Quebec and must be transported to BC by rail or other mode. Not perfect yet but hopefully one day soon.
