The right price
One of the big problems with algae biofuels is whether they will be cheap enough to produce. For people to start running their cars on a different fuel, it's got to be affordable - who wants to pay more than petrol prices to top up their tank?
'At the moment, making biofuel from algae is very expensive,' says Alan Scragg, a biofuels expert at the University of the West of England. 'The price of oil is still cheap in comparison, so we need financial incentives to start developing algae biofuels.'

As oil gets rarer and more expensive, algae biofuels might become cheaper in comparison.
