Aluminium hydrogen peroxide power system for an unmanned underwater vehicle

A modular approach to UUV propulsion using aluminum/oxygen

A modular approach to UUV (unmanned underwater vehicle) power source design and construction is described. A range of output power for near term UUVs from 300 W to 5 kW and a range of energy capacity from 15 to 500 kWh is considered. The different power and energy requirements are all met by use of a modular aluminum-oxygen semi-fuel cell with essentially

The story of Hugin – an autonomous underwater vehicle

The initial draft of the ''aluminium-hydrogen peroxide'' battery which the two researches jotted down at an airport in the United States was patented and industrialised and was in use in Hugin all the way until 2008. However, by the early 2000s, the battery technology had caught up with FFI''s patents.

Beyond metal–air battery, emerging aqueous metal–hydrogen peroxide

Amongst metal–H 2 O 2 batteries, H 2 O 2 was first applied to aluminum–hydrogen peroxide (Al–H 2 O 2) batteries in 1969. 22 Al–H 2 O 2 cells were successfully used by the US and Navy as a power source for UUV HUGIN-II and HUGIN-3000. 23-26 However, the severe self-discharge of this type of battery limits its wide application.
