US navy completes successful test on boat powered by algae

It looked like a pretty ordinary day on the water at the US naval base in Norfolk, Virginia: a few short bursts of speed, a nice tail wind, some test manoeuvres against an enemy boat.

But the 49ft gunboat had algae-based fuel in the tank in a test hailed by the navy yesterday as a milestone in its creation of a new, energy-saving strike force.

The experimental boat, intended for use in rivers and marshes and eventually destined for oil installations in the Middle East, operated on a 50/50 mix of algae-based fuel and diesel. "It ran just fine," said Rear Admiral Philip Cullom, who directs the navy's sustainability division.

The tests, conducted on Friday, are part of a broader drive within the navy to run 50% of its fleet on a mix of renewable fuels and nuclear power by 2020. The navy currently meets about 16% of its energy and fuel needs from nuclear power, with the rest from conventional sources.

The navy plans to roll out its first green strike force, a group of about 10 ships, submarines and planes running on a mix of biofuels and nuclear power, in 2012, with deployment in the field scheduled for 2016
