Million-dollar battery could help charge Casco Bay hybrid ferry

PORTLAND PRESS HERALD • May 24, 2021

A $1 million battery next to the Casco Bay Lines terminal in Portland could help charge a new hybrid diesel-electric ferry when it goes into service next year, if state utility regulators approve the pilot project. The vessel is expected to be one of the first fast-charging hybrid electric ferries in the United States, according to the Casco Bay Island Transit District. Adding energy storage could make it unique in the country.
