Green fuels set for breakthrough
July 14, 2004
Motorists who feel a pang of guilt every time they fill their tanks with pollutant-laden fossil fuels may soon find that they no longer have an excuse for not switching to cleaner alternatives.
Environmentally-friendly substitutes for petrol and diesel, long championed by green campaigners, have been commercially available for years.
But their high price relative to fossil fuels, along with the expense and inconvenience of adapting cars to run on them, has so far prevented them from penetrating the mass market.
Now, there are signs that a surge of entrepreneurial activity in the alternative fuels sector, coupled with rising oil prices and ever more strident warnings over climate change, could be about to change all that.
