How much compared to ICE engines running petrol or diesel?

Wow.. what a terrible solution.. he obviously hasn't watched the "gasland" doco.
I don't think electric cars or hydrogen cars are the Holy Grail of Zero emissions, however from where I'm sitting they are a much better option than what we have now for the environment.
Question is how much better and is it worth it for the environment.
Cost to the consumer is not the issue, like food,generally rubbish food is made cheaply, good food is the right price.
Hes saying that essentially they are taking methane (and i think other hydrocarbons) and breaking it into hydrogen and CO2, and releasing the CO2 to atmosphere, at an energy loss of 30% compared to the methane by itself (im not sure if that accounts for the energy input into processing the methane or if the end product has 30% less energy than the hydrogen).
Using locally sourced CNG would be a more efficient use of the energy (you dont lose the extra 30%) while shoring up australias fuel security.
I havent watched gasland but it appears to talk mainly about fracking? There are other ways to retrieve natural gas, which is where a lot of usable methane comes from.
As with most "renewable" or "green" vehicle fuels (including electricity), in Australia all they do is move the emissions somewhere else. There is a benefit for city populations as far as air pollution is concerned, but as a whole it is not a green, or renewable solution (at least at the moment)
