Marine vessels, or ships use up a lot of fuel, even more so, when the vessel in question is a giant one like a car carrier. Sanyo, Mitsui O.S.K. Lines and Mitsubishi Heavy Industries have come together to create a hybrid system that would make these vessels go easier on fuel, and a lot more environment friendly. The project also has blessings of Japan’s Ministry of Land, Infrastructure, Transport and Tourism, which will include it in its “Project to Develop Technologies for reduction of CO2 Emissions from New ships.”
The concept ship will have a photovoltaic system (solar panels) and a lithium ion battery system storing energy from the solar panels. The hybrid car carrier is scheduled to be completed in 2012, and it will have solar panels with a maximum capacity of 200kW, while the lithium battery’s max output will be at 3,000kW/h.
The hybrid ship will primarily use electric power at harbors, and diesel generators may be stopped for the said duration. While this accounts only for a small fraction of the time and total journey, the savings can still be huge, considering the emissions from such vessels.
