Hydrogen VS Electric vehicle questions?

1) What is the average price of hydrogen vehicles compared to electric vehicles?

2) What is the cost of refueling for both of them?

3) Do we actually have Hydrogen infrastructures in our country, or do we need to build them? For how much?

4) What is the efficiency of electrolysis compared to reforming fossil fuels?

5) Why are electric vehicles better than hydrogen vehicles?

    1)the hydrogen power car cost more then the electric to the difference being Electric cars cost around 250,000 dollar while the hydrogen car cost around a million dollar

    2) you can really tell how much that would pay because GM automobile took the electric car away before the public could really see it and hydrogen cars aren't even close to the public eyes except Arnold Schwarzenegger who can afford it

    3)there is not none because no one wants to save are country

    4)?

    5) electric cars are better because they cost less

    Hydrogen appears to be more expensive and in the case of the Honda FCX clarity ownership may not be an option. Honda appears to be following the GM EV-1 lease only model.

    FCX $660/mo lease compared to $350/mo lease for an electric Nissan Leaf.

    A few years ago I believe that Toyota offered an LNG camery for about $5000 over a standard gasoline engine. The FCX is considerable more expensive as its not using an internal combustion engine but rather a fuel cell to create electricity to operate electric drive motors. So in this respect the FCX is more like a Chevy Volt which is also leased at $350/mo.

    2.) Cost of refueling : Approx $2.00 gal equivalent for hydrogen, electricity is 0.14 to 0.17 /KW-Hr these costs are meaningless without conversion to a price per mile comparison and that will depend upon the efficiency of the vehicle and the energy content of the fuel etc...

    I am going to go with electricity as being the cheaper energy source.

    3.) Its hard enough to find an LNG filling station never mind a hydrogen one. Electricity already has an infrastructure in place and public charging stations can be easily added in locations where LNG or Hydrogen filling would be prohibited.

    4.) Efficiency of electrolysis. You can make a broad assumption that any energy conversion is 20% efficient. With that said fossil fuel to electricity is one 20% conversion while electrolysis requires an additional conversion from electricity to a gas.

    5.) Which one is better: I would give the edge to the electric . Consider how easy it is for a home owner to make fuel for a car. Yes one can make hydrogen or methane at home but compared to making electricity with a wind turbine or PV solar, electricity is much easier. It is far cheaper and simpler to recharge a battery than to generate, collect and compress a gas fuel like hydrogen

    As far as performance if your comparing apples to apples such as electric motor drive to another electric or between internal combustion engines each type have similar performance no matter what fuel source they use. There is a difference in energy density between fuel sources which impacts range and economics but this wouldn't effect engine performance much when considering normal driving.

    The only commercially available hydrogen vehicle is the Honda FCX clarity and the approximately 200 of them on the California roads are leased only. Although the original lease was $600/month I recently saw an article where this was increased to approximately $850. One recently brought to the UK had this review: http://www.autotrader.co.uk/articles/2010/09/cars/... In one review " ...the accompanying Honda rep said the car's price was in the millions, which is why the company only leased them, rather than sold them." http://www.hondareports.com/blog/1020599_another-c... Another recent article suggested that Honda was shifting with the market trend to electric vehicles.

    The price of electric vehicles varies widely with some like the Tesla Roadster at over $100,000 to a low of some neighborhood electric vehicles available for under $1000 with credits and incentives. After federal tax credits the Nissan Leaf is just over $25,000.

    Fuel prices vary as does the size of the battery capacity on electric vehicles. At the US national average price ($.1202)1 charging a Nissan Leaf would cost approximately $3.00 as literature says this is good for around 100 miles cost would be $.03 / mile. EPA estimates are less and the cost would be approximately $.04 / mile.

    There are a few hydrogen refueling stations in the US but basically the infrastructure is not there and investors are reluctant to supply them if the market does not exist. The cost would be Billions. to Trillions.

    Electrolysis is not as cost effective as gas reforming.

    You can use electrical energy to make hydrogen which can be used in a 50% efficient fuel cell electrical vehicle or you can use the power to charge batteries and run over 90% efficient battery electric vehicles. It makes sense to make electrical vehicles work. One way is to eliminate or reduce the size of the battery and use power transmitted through the roadways instead.2

    I think in 15 years 50% of the usa will be driving electric cars.
