Green Car Congress reports on how engineers at the University of Birmingham (UK) have developed a zero-emission hydrogen hybrid canal boat - 'The boat, called The Ross Barlow, is fully operational and demonstrates how a combination of magnet and fuel cell technologies could be used to power inland waterways craft'. The post continues:
The Ross Barlow was created by converting a standard maintenance boat which was donated to the University’s Protium Project by British Waterways. Engineers replaced the diesel engine with a NdFeB permanent magnet electric motor, lead-acid battery stack, metal hydride store, and 5 kW PEM fuel cell.

The motor is designed by the Lynch motor company, and is based on a brushed 4-quadrant axial flux motor, with a power output of 10 kW (13 hp) with a maximum efficiency of 89%. The NdFeB sintered magnets for the motor were manufactured by the Hydrogen Decrepitation process (HD process).
