Say Hi to Hydrogen - Honda rolls out new zero-emission car

You're right. To make hydrogen you need another energy such as oil but again oil consumption will be much less than the actual consumption.

Quote from kalzayani:

so how will da Hydrogen be made?...zero emissions from da car but made somewhere else
da same from battries...
Just another Nicroete subtitute for cigarttes...
I over Estiamte Public awareness I guess:D

Quote from limitdown:

crack spread is what they call the refiner process of breaking crude into combustable fuels,

I am not up on the hydrogen break process, other than the basic knowledge that it takes a micro reactor operating at high temperature to molecularly seperate the combustable hydrogen from the water in a vaporous state and then achieve collection and then subsequent combustion.

it would be interesting to see how they achieved this in an automobile package.

I will be looking for popular science magazine issue on this...

Fuel Cells do not use H for combustion, rather "reaction". The chemical reaction "power" from the fuel cell is converted into Electricity, which move the vehicle.

There are vehicles that use H for combustion, BMW 7 (Edward Norton, Cameron Diaz, opera star Placido Domingo and ultimate influencers Brad Pitt and Angelina Jolie.), but the H is not "made" in the vehicle, rather it is "pumped" in via a fueling station.

Just like that of gasoline, we don't fill up with "Crude Oil" and expect the vehicle to refine the oil into usable fuel.

BMW burns hydrogen in a conventional internal combustion engine. GM and Honda, like most other carmakers developing the technology, mix hydrogen gas with oxygen from the air in a device called a fuel cell to create electricity that drives electric motors.

Proponents note that hydrogen vehicles emit no greenhouses gases, unlike gasoline-powered cars. They have greater range than today's electric cars and can be refueled faster than a battery can be charged.

Solar power, wind farms, even Hydo-Electric (water flowing through dams) are example of pollutant free methods of generating Electricty to"crack" H20 into H. Yes, electrolosis IS the most inefficient method to produce H. But we are (we as in the human race) a clever bunch. I'm sure some guys sitting in their garage tinkering around will "discover" the most efficient method to separate H from H2O. When they do, I'm all over that IPO!

??? You won't be using oil to make hydrogen. You can make hydrogen a number of ways, but it most likely will be made by electrolysing water. The power will come from nuclear reactors, hydroelectric, or possibly wind, solar or geothermal.

We need far more nuclear reactors. Many bad decisions were made regarding nuclear reactors in the US during the 60's and 70's. We built horribly expensive one off plants that were way to big to manage either in the construction phase or the operational phase, whereas the French and Japanese built safe, smaller, one- design reactors at far lower cost. The French were disposing of reactor waste in glass casks dropped into the deep ocean. This is very safe and very practical, but i don't know if they still do it this way. We have way overreacted to the problem of disposing of spent fuels, and as a result wasted massive amounts of money once again.

By the way, by far the greatest proportion of US nuclear waste is from military programs. The waste from civilian reactors dwarf that from the military. So if your worried about reactors because of the nuclear waste your worries are misplaced. I would far rather live next to a nuclear reactor than a coal fired power plant. And here is another fact, coal fired power plants emit orders of magnitude more radioactivity into the atmosphere than do nuclear reactors (which don't emit any activity into the atmosphere).
 
Despite the high fossil fuel prices, hydrogen production is still predominantly from natural gas and oil because it is cheaper than electrolysis.
http://en.wikipedia.org/wiki/Hydrogen_economy
Currently, global hydrogen production is 48% from natural gas, 30% from oil, and 18% from coal; water electrolysis accounts for only 4%.[8] The distribution of production reflects the effects of thermodynamic constraints on economic choices: of the four methods for obtaining hydrogen, partial combustion of natural gas in a NGCC (natural gas combined cycle) power plant offers the most efficient chemical pathway and the greatest off-take of usable heat energy.

If I'm not mistaken we did it chemistry class, as far as I know there were not any reactors around.
 
Blah blah blah, BMW already made a hydrogen 7 series a year and a half ago...

Hydrogen is like ethanol. It looks good as a fuel until you find out the details and the economics and the environmental impact:

Why not just go the way of a hybrid plug-in vehicle with minimum premium over a regular hybrid?

You still have to plug it in. Where does that extra energy come from?
