The Royal Australian Navy will be converting its ships to be biofuel ready within six years in response to the US Navy’s move to biofuel use.

Under an agreement with the US, Australia is able to take advantage of the technologies developed by the US for biofuel use. A common approach is seen as critical for joint operations involving Australia and the US, which is expected to have its fleet converted by 2020.

The Royal Australian Navy plans to send a frigate and helicopter running on biofuel to the US Navy’s Great Green Fleet demonstration in 2016.
