Hydrogenesis fuel-cell ferry. This is the UK's first fuel-cell ferry. Here, it is passing Brunel's SS Great Britain in Bristol docks, Bristol, UK. Hydrogenesis's electric motor is powered by electricity from a fuel cell, fuelled by compressed hydrogen gas and oxygen. The only emission is water. Hydrogen fuel cells offer the possibility of pollution-free marine propulsion by renewable energy, providing the hydrogen is produced by electricity from renewable sources. Sailing ships such as the SS Great Britain are also propelled by renewable energy, in their case wind power. Photographed on 3 June 2013.
