Hydrogen powered cars tested

A number of trials of hydrogen-powered cars are underway around Australia, with proponents pushing them as a key to reducing greenhouse-gas emissions in the transport sector.

Hydrogen-electric vehicles are considered environmentally friendly because they only emit water.

They already are on the road in other parts of the world, and car manufacturers are hoping they will eventually be able to launch the cars in Australia.
