Hydrogen Powered Vehicle

The advantages of total heat cable cars are severe - no more smog-forming exhaust gases, no more atomic number 6 dioxide emissions that contri yete to global warming, no more worries of depleting the world's oil supplies and/or rising gas prices, etc. (Which). However, the total heat car is non without its problems, such as where does the henry come from, where do motorists film up, and how will cars store enthalpy furnish? Hydrogen is uncontrollable to store beca commit it is a gas at normal temperatures. It mustiness be packed tightly into the car's fuel tank to forfeit for longer runs, and to do this it must be liquified. The problem is that this posterior still be done by inputting large amounts of qualification - about 20 percent to 40 percent of the get-up-and-go content of the fuel - and the pressure needed to keep the hydrogen liquid and/or at temperatures approaching absolute zero, requires heavy, dear(predicate) tanks.

The special insulated tanks of the hydrogen-powered BMW cars displayed at the 2000 summer Olympics in Sydney, Australia held 140 liters of hydrogen - enough to run 300 kilometers (Which). A similar car fitted with a hydrogen-powered internal combustion engine had a be given of 400 kilometers on a tank holding all 75 liters of hydrogen. Internal combustion engines can be born-again to run on a variety of fuels including hydrogen, and again, when the hydrogen burns, the only byproduct is water. The high cost and high amoun

There is no problem with ever test out of sources of hydrogen since it is the most abundant element in the universe (Which). Natural gas is subjected to steam reforming to provide hydrogen for industry, and could also provide hydrogen to run cars. Fuel tanks on cars holding gasoline or methanol could perform the equal process on board to produce hydrogen for power. regrettably this option still emits smog-forming gases such as nitrogen oxides, but a method known as autoreforming is being positive which allows the process to be carried out at lower temperatures which do not result in smog-forming gas release.

Water is other source of hydrogen, and electrolysis could be used to split water into hydrogen and oxygen.

There is some appeal in the filling identify business of filling stations which would require no deliveries, and could use solar electricity and water to convert to hydrogen to recharge the storage tanks (Ring). Fleets of buses, rather than cars, may be the primary users of hydrogen engines, since they mostly discombobulate short runs and could induce storage facilities at their depots. Whether or not hydrogen cars make it to the streets and gain in popularity remains to be seen. There are many obstacles to be overcome first, though there is pressure to design a car which will not pollute the atmnsphere or cave in to global warming.

"Which way ahead for hydrogen cars?" May 2001. 14 Mar. 2005.

t of energy needed to liquefy hydrogen for fuel will probably be too problematic to build useful in the car industry, and cars will probably have to be refueled more often with compressed hydrogen gas. Scientists have discovered that several metals can absorb as a lot as a thousand times their own mountain of hydrogen, so this may lead to a new engine room which will make fuel cells whibh run on hydrogdn more practical.

Methanol can be run thro
