Crossing the Bay on Battery Power
In a recent article, Common Sense Eastern Shore proposed car ferries to cross the Bay as an option instead of a third bridge. We noted that there could be two ferries, one north and one south, and that ferry operations could begin in a shorter time span than that required to build another bridge. Now we would like to propose that the state consider looking at the advantage not only of the ferry as an option, but also electric ferries in particular.
Norway has been a pioneer in the use of electric ferries. Pictured above is the electric ferry Ampere, built by Fjellstrand Shipyard with Siemens and Corvus Energy. Use of electricity decreased emissions by 95% and costs by 80% (as compared with standard ferries), and decreased noise as well.
The first electric ferries in Canada will begin operation in 2020. Two units are scheduled for conversion. They will be powered primarily from batteries, but will have a diesel engine as backup. Their operational speed will be 13.8 mph. Two new, double-ended ferries will be operated by MTO, the ferry service of the Ministry of Transportation of Ontario. The Amherst Island ferry will accommodate up to 300 people and 42 cars. The Wolfe Island ferry will transport 399 passengers and 75 cars.
Washington State is in the process of developing a long-range plan/vision for ferry service there. In the meantime, they have conducted two hybrid conversion studies and concluded that a conversion of three Jumbo Mark II vessels would be fiscally, environmentally, and operationally advantageous.
In conclusion, we ask if yet another Bay Bridge is the best or only option for Maryland and the Eastern Shore. We believe that there are good reasons to consider ferry service instead, ideally with the use of electrically powered vessels. We wouldn’t be converting already operating vessels, as in Canada and in Washington State, and that might well be an advantage. Certainly, the use of electric vessels would be environmentally advantageous, as suggested in the Washington State study cited above.
