Hydrogen powered prototype vessel for inland waterways,

One of the most efficient means of transporting freight is by ship. Three years ago the University of Birmingham initiated an ambitious trial, converting an old canal barge to use hydrogen fuel. The old diesel motor, drive system and fuel tank were removed and replaced with a high efficiency electric motor, a battery pack for short term energy supply and a fuel cell with a hydrogen storage system to charge the batteries. In September 2007 the converted boat,

Based on experience with other battery driven canal boats it was decided to use a 10 kW permanent magnet motor. To provide energy for longer trips a commercial fuel cell delivering 1 kW of power was chosen. This system was originally designed as an uninterruptible power supply (UPS) for use in the telephone industry. The capacity of the fuel cell was,

The hydrogen supply for the fuel cell was provided by hydride storage system developed by Empa and partly financed by the Swiss Federal Office of Energy (SFOE). This device can store hydrogen with an energy content of 50 kWh, which is equivalent to 20 pressurized gas cylinders each of 10 Liter capacity. The storage material consists of an alloy of titanium,

Charging and discharging cycles for the next 100 years!

The journey through canals and locks makes widely varying demands on the barge’s electrical supply. To save wear and tear on the fuel cell,

A typical journey takes 4 to 6 hours during which time the canal boat uses 12 to 18 kWh of power. In continuous operation the fuel cell delivers 24 kWh of energy per day. This also powers the electronic monitoring system,

The reliability and operational lifetime of the metal hydride storage system was tested in the laboratory during its development. In practical terms this means that when used to power the "Ross Barlow", if the ship is assumed to travel 650 km per year through the British canal system,

The results of the test voyage

During the 105 km,

The batteries supplied 71 per cent of this energy, the hydrogen fuel cell 25 per cent and the solar panel 4 per cent. There was unanimous praise from the crew for the practically silent way the boat sailed. Also notable was that when waiting in a lock the "Ross Barlow" was not engulfed by its own diesel fumes. The boat which accompanied it (which was about the same size) used some 50 L of diesel,

The "Ross Barlow" on the other hand produced no CO2 during its voyage, assuming that the hydrogen it used was derived from renewable sources and delivered free of emissions to the refueling point on the bank of the canal.
