On a global level, hydrogen technology addresses the growing gaps in the supply of fossil fuels. More specifically, it is the only fuel that can allow for a reduction in the overall emission cycle, while meeting our energy needs in a sustainable way. Besides, not many fuels can be produced from renewable sources such as sun, wind, water and biomass.
Determined to bring the power of hydrogen to the world, our initiative goes far beyond the vehicle itself. We are already collaborating with a wide range of dedicated partners, from global fuel distributors and fuel technology companies to government agencies and environmental groups. Today in Germany, there are five liquid hydrogen refueling stations - and soon there will be two in the US. Developed with Linde AG, they are virtually as easy to use as normal gasoline pumps.
If I understood that right, hydrogen is already well accepted as a magnificent fuel. The only problems it still faces is regarding safe storage in light tanks inside the car. - What is your opinion on that?
I look any prototipe in Europe where the tanks is down the car sean the tanks of petrol . But the problem is the tanks is very BIG.
If you get very small tanks is possible you get more security for protect this tanks and also the risk is more low in case of accident
About Hydrogen Storage
I get some information:
About storage and fabrication Honda have any project
Look in : STATION
@Honda Photo:
Rather than using thousands of psi to compress hydrogen into a tank, or cooling it down to minus 252°C (minus 421° F) to liquefy it, an intriguing alternative of hydrogen storage has led to metal hydrides, chemical hydrides, and physisorption-based storage, where hydrogen is adsorbed onto the interior surfaces of a porous material. The stored hydrogen can then be released by heat, electricity, or chemical reaction. Many metals are capable of absorbing hydrogen as well. Nanotechnology plays an important role here. Nanomaterials have diverse tunable physical properties as a function of their size and shape due to strong quantum confinement effects and large surface to volume ratios. These properties are useful for designing hydrogen storage materials. For instance, researchers are now investigating nanostructured polymeric materials as hydrogen storage adsorbents. The new polymer adsorbent material has shown great promise in preliminary tests.
| Due to their large surface areas with relatively small m *, single-walled carbon nanotubes (SWCNTs) have been considered very promising potential materials for high capacity hydrogen storage. Theoretically, they can store hydrogen up to 7.7 wt%, as every carbon atom in SWCNTs chemisorbs one hydrogen atom. In addition, the subsequent physisorption of hydrogen on the surfaces of hydrogenated SWCNTs can increase the capacity of hydrogen storage even further. However, there is some skepticism on carbon nanotube hydrogen storage due to early mistakes in experimental publications and a rational basis for high capacity hydrogen storage material is now beging developed. | |

| Not surprisingly, a fuel cell is essentially just the reverse of an electrolytic cell: whereas electricity is used to decompose water into its constituent gases during electrolysis, in a fuel cell water and electricity are generated by the direct recombination of hydrogen and oxygen. | |
Good info! Thank you so much! ![[em19]](http://img.alibaba.com/images/eng/style/icon/emoticons_great.gif){kind=icon}
Something very important you didn't mention is the fact that these storage solutions (like carbon nano tubes) also typically make the hydrogen less combustible or explosive. Quite an advantage!

I am thinking in all this. I have my old automobile in the door and I not change because I like one use hydrogen. I think I no go to wait 4 or 5 years or only 1!!!!
I go to inprove any solution.
One year only? I would love to see your prediction come true!
Any specific reason you are so optimistic?

Why don't we mention the "taboo" word "Hydrogen on Demand" systems. Instead of lugging around huge and bulky tanks of hydrogen (which in itself is a safety hazard). Not considering that hydrogen itself also has a permanent "leakage" problem where the volatile gas can seep out of relatively "air tight" tanks in short periods of time. Why not carry the hydrogen in its most safe and logical form as H20 = WATER where 1 gallon of water = 1833 gallons of HHO gas and let "onboard" splitting systems with less energy than it takes to power a car stereo or much less than an A/C system are able to deliver gratuitous amounts of Hydrogen alone (with the Oxygen vented) or the combined gas HHO (which is an even more efficient fuel) to supplement existing engine's traditional fuel supply. Just as NASA in its space flights or thousands of "tinkerers" and experimenters (myself included) throughout the world are doing much to the displeasure of the oil companies and certain corporate interests today.
The problem with this concept is that also the energy used to split the water molecules has to be onboard. Perceivably that could be in the form of solar energy (PV) modules, but still so, you would make much better use of the captured energy if you sent it directly to electric motors than first splitting water into HHO and burinig that in an engine.
Technically your concept is not a problem, but economically it is, as you are adding an extra step that's not needed or beneficial.

Precisely thats the beauty of the concept! That the system is self contained. In the same way as a fossil fuel vehicle prepares and atomizes the fuel to be used by the engine. The portable electrolizer or gas generator or fuel cell provides "hydrogen on demand" to eliminate the need to carry an highly explosive cargo as would be the case with hydrogen tanks. As a matter of fact we already carry a portable electrolysis unit which happens to be the car battery (which is highly explosive if we put a match near to it). But which is simply not designed to give adequate amounts of Hydrogen for combustion purposes.
Therefore I believe that instead of just "adding" an unneeded or not beneficial step as you would describe it. It would become a highly beneficial safety feature. Although we cannot do away for now with the traditional gas tanks which have been involved in so many unfortunate accidents. We are certainly expecting the day when fossil fuels will be done away with and we'll all be driving 100% non-polluting vehicles.
I would like to suggest an interesting series of interviews by the curator of the Water Fuel Museum in Lexington, KY Mr James Robey (at www.blogtalkradio.com and place "water fuel" on the search line) and we can get back later on this fascinating subject. Pls email on sogans@yahoo.com
On electric motors I perfectly agree that these are among the most efficient ways to power an engine but what I consider is the cost which today are prohibitive unless if you are looking for performance. Also the range is another aspect to consider. We may check the Tesla Motor Co. model vehicles.
But if economy is in mind there are many 100% electrical economical scooters and light vehicles being manufactured in Asia which perfectly accomplish this purpose and most important, today. As a matter of fact I read that in Katmandu, Nepal there is a strict city rule which only allow this type of vehicle in order to preserve the nation's most valuable resource, its pristine environment.
As for alternate power generation solar or eolic powered gas generation can be employed to power gas generators therefore "boosting" and multiplying the energy potential many times over than if we were to only employ solar panels or wind generation alone.
Its certainly a pleasure to participate in this highly prestigous panel.

A reader of this blog, Burt B. has sent in some concerns that water vapor from hydrogen cars may contribute to greenhouse gases.
Burt B: “I saw the BMW Hydrogen 7 advertised on CNN this morning. It looks like the technology is maturing. I have questions about the water emissions. The water that is made by hydrogen fuel combustion, and I guess fuel cells, probably shares characteristics of distilled water. I understand that distilled water is more corrosive than natural water. Might it become a waste disposal problem?
How will the water be handled? There are three methods that I can think of: misting it into the air, allowing condensed water to drip onto the road and storing it in onboard tanks for draining at a convenient time and place, probably when fueling … can you please explain what happens to the water created by using hydrogen fuel?”
Hydro Kevin: “Thanks for your questions about hydrogen. I’ve talked about water vapor from hydrogen fuel cells and greenhouse gases before. But, I also want to add some new information as well.
For instance, many people make the assumption that hydrogen internal combustion engine and fuel cell cars give off water vapor from the tailpipe but gasoline-powered cars don’t and this is not accurate.
Here is a quote from the MadSci network about the chemical makeup of gasoline, ‘Although gasoline contains many different chemical compounds, it is made up mostly of hydrocarbons, and all hydrocarbons form the same products when they are burned (just in different amounts). When a hydrocarbon is burned (that is, reacted with oxygen), it forms carbon dioxide (CO2) and water (H2O). For our average gasoline of C8H18, the reaction is 2 molecules of octane reacting with 25 molecules of oxygen (O2) to form 18 molecules of water and 16 molecules of carbon dioxide.’
So, the point is that gasoline-powered vehicles are already putting out tailpipe emissions that contain a noticeable amount of water vapor into the air. It’s the carbon dioxide, carbon monoxide and nitrous oxide emissions that we need to stay focused on cleaning up above and beyond the water vapor, which is the natural ingredient in clouds.
As to distilled water being more corrosive that natural water, here is a quote about distilled water from the Wise Geek website, ‘Natural water usually contains a number of microscopic contaminants, along with dissolved minerals such as calcium and iron. One way to remove these elements from water is to boil it until it changes to steam, a process known as distillation. When this steam is allowed to cool down and condense into liquid form again, the result is a purified form called distilled water. Distilled water should ideally be nothing but hydrogen and oxygen molecules, with a PH level of 7 and no additional gases, minerals or contaminants.’
