In an attempt to improve the range of Unmanned Undersea Vehicles (UUVs), the alternative
energy company AlumiFuel Power Inc, (API) researching on behalf of the US Navy, into
possible use of hydrogen generation using steam and aluminum. This method produces the gas
using aluminum and steam (water) in a controlled exothermic reaction to producing hydrogen
gas, water and aluminum oxide. The rate of hydrogen emitted is simply controlled by the supply
of steam reacting with the aluminum which can be fed straight to a fuel cell or combustion
engine. [More]

Last month, GL Group, presented a future concept of a zero-emission container feeder vessel.
The container ship, aimed at Northern European feeder services, uses liquid hydrogen as fuel to generate power with a combined fuel cell and battery system. The design of the container ship with capacity for 1000TEUs with 150 reefer slots, is for a full open top giving improved port efficiency and reduced loading / unloading times to further reduce CO2 emissions. Propulsion is by two azimuthing podded propulsors and one take me home thruster providing redundancy and superior manoeuverability. The service speed is 15kn. The concept envisions that the liquid hydrogen would be produced and stored offshore close to a wind farm. The cost of liquid hydrogen is higher than marine gas oil (MGO), however, costs could be similar after 2025 if emission surcharges are introduced. [More]

Fuel Cell Vessel Back In Service

The 100 passenger Hamburg, Germany tourist vessel Alsterwasser is back in service after refurbishment following a devastating fire last year. The hydrogen fueled vessel has two 50 kW (67 hp) fuel cells powering a100kW (134 hp) hybrid electric propulsion system with lead acid batteries. The vessel was built in 2007 and entered service in 2008. The hull has an LOA of 25.5 m (84 ft), beam 5.2 m (17 ft), a draft (laden) of 1.3 m (4.2 ft) and displacement of 72 tonnes (79 tons). The maximum height of 2.6 m (8.5 ft) can be reduced to 2.3 m (7.5 ft) by lowering the cabin roof to allow passage under low bridges. The ship including fuel cell propulsion system is classified by Germanischer Lloyd. The hydrogen is sufficient for three days power supply, refueling takes approximately 12 minutes. The annual nett benefit to the environment is a saving of 1,000 kg of NOx (1.1 tons), 220 kg (485 lbs) SOx, 40 g (1.4 oz) of particulate and 70 tonnes (77 tons) of CO2. [More]
