Stena Line, one of the world’s largest ferry lines, is powering one of their ferries through renewable means. Currently, the line is already environmentally certified according to ISO 14001, but the company plans on going a step further. Their ship, the Stena Jutlandica, Gothenburg-Fredrikshaven, is being equipped with two wind turbines. While this is one of the first ships to utilize wind, it is not the first to utilize renewable energy.
The turbines will be located on 4 meter high masts on the front of the ship and not only produce 23,000 kWh per year, but also reduce air resistance. The electricity will be used, among other things, to light up the car deck. The reduction in air resistance will lead to reduced fuel consumption of about 80-90 tons a year. The two vertical turbines will generate 4 kW of energy each and offset 269 tons of carbon dioxide a year as well as 1.7 tons of sulfur emissions.
Aside from the current project, Stena Line has 200 other environmental improvement projects that they are pursuing within their Energy Savings Program. It offers some 17 ferry routes in Scandinavia and in the UK, connections between eight countries in the region, and operates 35 vessels.
