Hydrogen Buses In Iceland 465
dapyx writes "As part of the shift away from the fossil fuels, Iceland began its switch to hydrogen-powered buses, which are now used on the streets of the capital, Reykjavik. About 70 percent of Iceland's energy is already met by green power. Iceland plans to become the first oil-free country by 2050."

Except that hydrogen isn't found, or mined, it's created. Either from fossil fuels or by electrolyzing water, which requires electricity, which comes from fossil fuels.
How are they generating the hydrogen?
It's easy for iceland to claim 70% "green" because geothermal heating is a real option for them. The air is cold, the earth is hot. It doesn't work for most of the rest of the world. There's nothing for me to dig into but cold muck and the chesapeake watershed.

elsewhere, you got this 'nukularrrr' reaction that you can use to create power to break down that water. but don't tell the ecomaniacs, they wouldn't want you to save the earth.
(honestly, that's just about the only REALISTICAL option for breaking water down to hydrogen on big enough scale. hydrogen is just a way to store energy in this case and the energy HAS to come from somewhere, and the 'eco' sources are not that plentiful or viable to be used in the scale that replacing oil dependency needs.. my opinion? that we won't move into such direction on large scale before we have fusion as viable energy source)

With distributed computing catching on, this might not be such a bad idea. How many people own or otherwise use exercise equipment? (i know, wrong place to ask). It shouldnt be too hard to convert those machines into generators and have them dump their power into the grid. Individually, each person may generate an insignificant amount of electricity, but it all adds up.
I'm picturing a World War II style government propaganda blitz with "victory workouts" replacing victory gardens.

If you have a source of carbon dioxide handy, you could just convert the hydrogen to methane (2H2 + CO2 = CH4 + O2) and just have the end users burn the methane in an internal combustion engine instead. Or use steam reformation to re-release the CO2 and split it from the Hydrogen.
Anyway, Hydrogen has a very nasty habit of leaking from just about every containment vessel ever produced. When it leaks, it goes up. Due to its extremely low weight, it reaches escape velocity and goes into space, though there's a good chance some of it will do a bit of melding with atmospheric ozone on its way up and even further wreck the ozone layer.
If we produce heaps of hydrogen and half of it ends up going into space, even if the energy source for producing the hydrogen is renewable, the fuel certainly isn't.

Nobody is claiming that hydrogen is an "original" power source, just that it's a better carrier than even the best batteries in an electric car, which is why it'll be used when oil runs out (assuming batteries won't get any development meanwhile). The electricity can originally be created with environment friendly nuclear plants, or in Iceland's case, geothermal heating.
Nuclear energy is cleaner than burning any fossil fuels. This is really a no-brainer.

That is the least of the reasons why hydrogen isn't a good alternative fuel supply. The main reason being that it isn't a fuel supply at all. It is a storage medium... and not a very good one at that. But I guess if you are swimming in geothermal energy like Iceland is, it makes more sense to waste some of the energy using hydrogen than it does to import oil. For the rest of us, oil is extremely convenient form of energy. All you need to do is pump it out of the ground and process it a little... and maybe go to war from time to time.
If this country (USA) wants to get off its coal, natural gas, and petroleum dependency, it has to build new nuclear power plants to power homes and use that to generate hydrogen to power vehicles. No new nuclear power plant has been built since the Three Mile Island incident, which similar to Chernobyl, was a combination of untrained workers and poor design.
Sorry, the "too cheap to meter" dream died a long time ago. Get with the times, man. There are more reasons than fear that keep us from moving all power to nuclear. Fossil fuels are just too damn convenient and still plentiful enough.
