A Jersey-based scientist says sand from the island's beaches could be turned into hydrogen and used to power cars.
The technology to use sand is already being used in Europe
Dr Anthony Hayden-Taylor's company has bought the technology development rights which may provide an alternative energy source to fossil fuels.
Dr Hayden-Taylor says Recycled Refuse International could become one of the world's leading suppliers of silicon.
He believes his firm will be in full commercial production turning silicon to hydrogen to be used to power cars.
A plant in the United Arab Emirates has already been set up and sand from Abu Dhabi has been tested.
But Dr Hayden-Taylor says he has had interest from the UK and Europe where the technology is already working.
So far no States member in Jersey has backed his plan.
