Apart from Solar, Hydro, Geo-Thermal, Wind, Tidal, Biomass etc, one major fuel of the future to boot is Hydrogen. Barring the cost factor, it seems to be the perfect fuel of future. To address cost factor, lot of R&D is being carried out world over. US and Europe are putting in Millions to minimize More >

h2 auto's zijn groen als de energie die sperates de h2 kwam uit groene bronnen, zoals zonne-panelen of zo. een soort h2 auto gebruikt een pem-cel het samenstellen van h2 met ogygen uit de lucht, en het nemen van de elektrische voeding van te maken. het voordeel is, dat die auto's stoten niets anders dan een beetje water. maar zoals reeds gezegd, de technologie is zinloos, tenzij de productie van waterstof betekent niet dat het branden van fossiele brandstof of zo

James, you have got it. Hydrogen powered cars are a joke, and not just because they consume more power than they produce.
How are they going to store fuel in a moving vehicle?. Hydrogen has a habit of leaking from the tiniest cracks, cracks that would stop other gases except for helium. It can only be stored as a gas in the practical real world, which means it’s energy density is pathetic compared to petrol/gasoline. It is also explosive when mixed with air over a range of about 5% to 74%, a far, far wider range than petrol/gasoline vapor, so it is also far more dangerous.
Far better to use an hydrogen rich fuel like methane as CNG -compressed natural gas or as the more carbon intensive but still hydrogen rich fuels like liquid petroleum gas or LPG, which can be stored as a liquid at moderate pressure and ambient temperature.

That depends on the energy source used for that separation. If solar or wind energy is used, then you have a “green’ fuel. Hydrogen can be used as any other fuel, but with some changes if you want to do it right. Putting th gas line down into the air intake will work, but it has it’s problems. There is a special injector made for this fuel, but right now it is fairly expensive.
An easier fuel would be methane derived from animal waste. It needs to be scrubbed of other gasses, but a lime water filter will take care of that. The only real problem then is to compress it. The only free transportation is still walking, or riding a bicycle. Everything else has some kind of problem to go with it.

You’re right and storage is a huge problem. With today’s technology and that for the foreseeable future, a cars range is about 100 miles and because of leakage, even if you don’t drive it, the tank will leak itself empty in about a week.

That is part of it. The H atom is so small it will leak through anything ,and explode. If your car has a 10 gal tank it could wipe out a hole block. It would also produce NO2 ,due to the Burning temperature.

Waterstof brandstofcel auto's zijn een beetje grap. Mijn theorie is dat ze er een beetje van oplichterij te helpen de oliemaatschappijen om te overleven. Hoe dan ook heres sommige titbits ik ontdekt, terwijl onderzoek naar de verschillende aandrijflijn efficiëntie van de verschillende voertuigen – Pak de waterstof uit koolwaterstoffen een bron is erg vuil. Ik berekend als waterstof is uitsluitend geproduceerd die manier wordt de CO2-uitstoot van zou worden 120 + / -10g/km voor een kleine hatchback. Hoewel de emissies zijn natuurlijk nul uit de auto zelf. – Het kost drie maal zoveel energie voor het uitlezen van waterstof via elektrolyse zijn dan de maximaal mogelijke energie die kan worden gewonnen uit (dit is een fysieke contraint, eigenlijk zijn dichter bij de 1 / 5). Uitgaande van een brandstofcel heeft een maximale efficiëntie van ongeveer 45%, dan is de veronderstelling dat je had een goede elektrische motor met terugwinning van warmte op 95% efficiëntie, het proces wordt 0.33×0.45×0.95 = ongeveer 0,13%, in het beste geval! Hierbij wordt voorbijgegaan aan de efficiëntie van de elektriciteitsproductie-ook! Gezien koolwaterstoffen zijn over het geheel genomen ongeveer 30% over de hele stroom thats pretty wastefull. — De efficiëntie van de macht trein ongeveer gelijk is aan benzine, iets slechter dan deisel. – De energie-dichtheid van waterstof bij 200Pa is ongeveer 1 / 10 van die van benzine, dit kan worden verbeterd door liquifying zij tot ongeveer 1 / 4. Dit betekent in wezen dat de omvang te produceren theoretisch dezelfde hoeveelheid energie is veel groter voor waterstof dan benzine. Dit is geen vermelding van de volatiliteit van waterstof, en de bezorgdheid over de veiligheid dat er nog bij. Mijn advies, wacht u voor batterijen aan het vinden van een betere energie-dichtheid, een brandstofcel is in wezen een tussenpersoon die op energieverspilling. De efficiëntie van de aandrijving voor een EV liep op batterijen is dezelfde / vergelijkbaar met de elektromotor, de bron van de elektromotor is de enige zorg is, geproduceerd op industriële schaal zijn vrij efficiënt. Ik werkte op de CO2-uitstoot van een elektrisch voertuig op batterijen deze dagen zou worden 30g/km.

For example creating all your hydrogen from electricity generated by renewable sustainable means that you want there is that it solar wind power wave power source of energy such that one sussed out yet the primary power hydroelectric into clean acceptable secondary.

Engines can be made to burn various kinds of fuel including hydrogen. The really non-green thing about a hydrogen powered is that hydrogen on an industrial scale is made from methane (nat gas).

First, the answer to the question as asked – If you make the hydrogen from natural gas (~97% methane), it is not extraordinarily clean or efficient. The only benefit from this is that it concentrates the “mess” in one place where, at least theoretically, it’s easier to capture/contain/control. I’ve never met anyone that would tell you that this is how to realize the benefits of a hydrogen economy. The ideal scenario is one others here have described… you need to use renewable and clean energy not only to electrolyze the water, but also to compress the hydrogen to usuable vehicle pressures. Then you put it in a PEM fuel cell which generates electricity and water, and the cycle continues. If the energy you’re using is renewable and clean, then the efficiencies involved are less of an issue. This is done currently only on small scales for economic reasons, but is certainly possible.
_________________________
Issues brought up by others…
Most H2 powered vehicles today run on compressed gas, but other options are out there. The driving range of vehicles varies enormously, largely dependent on the amount of space the manufacturer has been able to manage for the tank (sometimes at the expense of a trunk in a prototype). Several are in the 200-300 mile range, and tank pressures are being doubled in the next generation (2x far for the same size tank). The hydrogen does not all leak out of the tank.
Hydrogen is quite small and leaks easily, but can be contained and used safely with proper design. Gasoline has at least as many “dangerous” traits, including pooling under a vehicle and being toxic, neither of which is true of hydrogen. Hydrogen is non-toxic. It is also very light and diffuses away from a leak source quickly, making accumulation unlikely. There is an incredible amount of work going into using hydrogen safely in cars – it’s been used safely in industry for years. The key, as with any fuel, is to know it’s properties and treat it with respect.
H2 can be used in an internal combustion engine (with a small amount of emissions), or a fuel cell (“zero emission”). There is still work to be done for sure, but it’s not as bad as it’s being made out to be!
