The first of two cutting edge “hybrid” ferries named Hallaig, built by Ferguson Shipyard, and the first of its kind in the world was launched on the Clyde yesterday, Dec. 17th, by Deputy First Minister Nicola Sturgeon. The vessel will be powered by small diesel generator sets, feeding power to a 400 volt switchboard, which will supply power to electric propulsion motors that turn the propellers.
In addition the battery banks will provide power to operate the vessel.
Benefits of the hybrid ferries include reduced fuel consumption and impact of CO2 emission and other pollutants, noise reduction and lower maintenance requirements. The ferries will charge overnight while they are moored on the islands they will serve and it is hoped that in the future energy from local wind, wave or solar systems will be used to charge the batteries, making the process even more environmentally friendly.
The ferries will accommodate 150 passengers, 23 cars or two HGVs, with a service speed of nine knots.
