Hydrogen a more viable car fuel now

 The technology is based on a new way of producing nano-fibers from hydrides, materials that soak up hydrogen like a sponge, and then encapsulating them in tiny plastic beads so small they behave like a liquid. The process is being developed by Cella Energy, a spin-off from Britain's Rutherford Appleton Laboratory, who says  that the technique allows hydrogen to be released at a much faster rate and at lower temperatures than before.

“What we've been doing is taking these materials and encasing them in plastic and making them into a very fine powder and that improves their properties,” Cella Energy Chief Scientific Officer Stephen Bennington said.

“It also means you can pump it like a fluid and it's safe. It is not gong to easily burst into flames,” he said.

Hydrogen produces only water when its burned and is considered an ideal solution to cutting carbon emissions from petrol or diesel vehicles, which are estimated to cause 25  per cent of all carbon release.  But until now  attempts to store hydrogen have not been consumer-friendly so this has not been a viable option. Cella Energy Ltd say their technology would allow people to use the carbon-free fuel with their existing car after a few modifications.

“You would pump it into your petrol tank of your car -- that would go off, be heated, drive the hydrogen off, which would go and run your vehicle and then the waste little beads that we have created you store in the car. And when you go and refuel your car you have two nozzles. One which puts in the new beads and one which takes out the old beads which goes off to be recycled and the hydrogen added to it again,” Bennington said.
“The experience that most people have now is using regular liquid fuels where it takes three minutes to fill your vehicle and then you can travel 300 miles,” said Stephen Voller, Cella Energy's CEO.

The company said hydrogen could be an economically viable alternative to fossil fuels if the gas is produced with renewable energy sources like wind or solar. It has three times more energy than petrol per unit of weight and could power cars, planes and other vehicles that currently use hydrocarbons. All part of the reason Cella Energy believe their process could herald a new era of carbon-free motoring.
