Honda hydrogen car??

[coffeeman]

Just heard about a hydrogen car made by Honda. In limited production by 09 or there about. The real thing here is Honda is working on a little hydrogen plant that can be a home model. I guess it's the long way around because you will not see big oil promoting this fuel. I read it would be cheaper if done in hugh plants. However, it would be nice to keep the big companies out of the supply business. Honda has teamed up with GM. If they could pull off these home plants, what a new industry! A little hydrogen plant in every home. Multiply the homes that need these plants by a few thousand dollars profit. Nice new industry being created. By the way, things change fast. About 6 months ago Popular Science magazine listed hygrogen as one of the least likely alternative fuels. If I understand right, Honda has improved the way hydrogen can be stored in to car for use. They have a 350 mile range per fill up.

Check it out. Search Honda, hydrogen and GM. Some nice stories to dream about.

BMW 7-series (hydrogen) will be out in 6 months.

It would be nice to have "A little hydrogen plant in every home" Problem is it will not happen (I think). Same thing was said about fuel cells about 10 years ago.

Your probably right. There is a wild card here, though. If auto company produces an alternative car they still sell about same number of units. In this case they have potential to sell the car and sell the home plant;almost like selling an extra car for for each sale. Honda and GM (not down and out yet) seem to think a little about this idea. Lots of $$$ could be made here.

If the "little hydrogen plant home model" was as good as a Honda, heck I would buy one!

So you use electricty or natural gas to generate hydrogen. So the green house gases are still generated and actually go up a lot because an additional process is required and no process is 100% efficient.
Why not use a hybrid car as a backup for your house. When on the road they are very efficient, and at least some of the energy directly drives the wheels, green house gasses and energy is saved. They could drive the grid during peak useage and the car will probably be at home if you are using much electricity. We also have a lot of experience handling gasoline. Hydrogen is very good at leaking as the molecules are very small and have low viscosity.
Please tell me how hydrogen is better. It is not actually a fuel source but must be made from another fuel source. It's high combusiton temperature during burning will probably generate nitrous oxides. It will waste energy. It takes a lot of room to store it (Honda claims to have fixed this). The systems are very expensive.

I'm highly doubtful that hydrogen will ever be a truly viable fuel for automobiles. We don't have an efficient way to produce it - water electrolosis is the only real way to get large quantities of it, and it takes more energy in the form of electricity going into the process than the energy you get out of the hydrogen either by burning it or using it in a fuel cell. The only place it works is in Iceland where they're using their seemingly limitless supply of hydrothermal power to make the electricity to split H2O into H2 and O. Here we would have to burn coal, oil, or natural gas to get the electricity to make H2 out of water.

The stuff is also notoriously hard to store and carry around with you. It takes a pretty large very high pressure tank to hold H2 in gaseous form, or a very large, very cold tank to hold it in liquid form. It's also such a small molecule that few materials can hold it without leaking at least a little of it away, and all of the plumbing and valving required to move it around will be well nigh impossible to keep from leaking. Oh yeah...it's also some of the most volatile stuff in the universe, think rocket fuel and the element stars burn in their atomic fusion bellies.

Unless someone can find a huge store of liquid hydrogen or hydrogen ice floating in space (and space is actually too hot for that to happen), H2 power ain't gonna' happen. I would go for natural gas engines long before a hydrogen economy could work. Heck...I'd venture a guess that we'll find a way to harness fusion power (the opposite of nuclear energy) before hydrogen becomes economical.

I would go for natural gas engines

Honda already has one of these available in the civic. You can also get the home recharging station for it. I would own one if they would run the NG down my street

The news had an article about tests on a Prius using high pressure nitrogen gas instead of the batteries. It would reduce the weight of the vehicle a lot to make it more tossable around curves.

Big Charlie has it right; hydrogen is no solution to our energy problems. Hydrogen is expensive to make, expensive to store, and expensive to transport. Because its energy density per unit of volume is so low, a tanker truck full of hydrogen would use up the equivalent amount of energy in the tank if it were to carry it for more than 200 miles. That is why centralized production of hydrogen is not feasible. You need to make it very near to where it will be used to avoid the high energy loss due to transport. Hydrogen shouldn't really even be thought of as a fuel at all. It's actually more of an "energy transfer medium" much like electricity. You use some energy up front to make the hydrogen, and then you get some smaller fraction of that energy back when you burn the hydrogen or use it in a fuel cell. The only time you should even consider using it as an energy source is when you cannot use the primary energy source directly. Currently around 90% of hydrogen is made by steam reformation of natural gas, because that is the cheapest way to make it. You'd be much further ahead efficiency wise to build a car that runs directly on natural gas and skip the hydrogen middle man entirely. The "Hydrogen Highway" project out in California is a dead end road for sure. Unfortunately for the taxpayers out there they are going to have to learn the expensive way.

We could all be little willie s with those home energy plants.
