Water from the sea could power cars of the future, if experiments currently being trialled by the US Navy prove to be successful.

According to Jalopnik, the US Naval Research Laboratory is turning carbon dioxide from seawater into hydrogen, with the hope of fuelling its jets from alternative sources.

If successful, researchers predict it’ll cost between $3 and $6 per gallon – that’s approximately 40p to 80p per litre.

Manufacturers are already trialling hydrogen-powered cars, with Hyundai saying a mass produced zero-emission fuel-cell car could be on sale as soon as next year.

Unlike electric cars, hydrogen-powered cars can be refuelled quickly and have the range of conventional petrol engined cars.

However, there is currently no network of hydrogen refuelling stations anywhere in the world – and providing them would be costly.

The technology is also expensive, meaning hydrogen-powered cars are likely to be considerably pricier than their petrol-powered equivalents.

But, with petrol and diesel prices on the increase, could seawater be the answer?
