    Too bad it is a trade off in environmental protection for bad environment in another. The mining of lithium for lithium ion batteries has been killing the environment. The other side is the environmental problems at the end of the batteries life.

    Too bad you are so ill informed. The most productive lithium mines are in deserts in South America, and the hard rock lithium mines are far less polluting than this;

    Then add in things like the national electrical grid is only about 3% renewable energy.
    The transportation of the battery parts is not eco friendly.
    Most if not all batteries contain plastics that come from oil.
    Could continue but I think most see that it is a start but it is mostly optics.

    I see that you and the article has left out some information that makes these electric ferries be a niche player, compared to the existing Seattle Ferries.:

    Note this is the WORLDS LARGEST Electric ferry to date, meaning just a few months ago.

    Now contrast this to the STANDARD Passenger/Car ferries in Seattle, from Wikipedia:


    and,

    Not even close!

    They claim that the all-electric ferry cuts emissions by 95% and costs by 80%.

    They wrote in a press release:

    The world’s largest all-electric ferry, named Eferry Ellen, made its first commercial trip early this morning, Thursday, August 15, 2019, connecting the ports of Søby and Fynshav, on the islands of Aerø and Als, in southern Denmark. This revolutionary ship, capable of carrying approximately 30 vehicles and 200 passengers, is powered by a battery system with an unprecedented capacity of 4.3MWh provided by Leclanché SA (SIX: LECN), one of the world’s leading energy storage companies.

    The company claims that the ferry alone will “prevent the release of 2000 tonnes of CO2, 42 tonnes of NOX, 2.5 tonnes of particulates and 1.4 tonnes of SO2 into the atmosphere” on an annual basis.

    Last year, it was announced that two big new all-electric ferries are coming to Canada.

    Delivery of the Amherst Island ferry, which has a length of 68 m, a width of 25 m, and can accommodate up to 300 people and 42 cars, is expected in 2020. The Wolfe Island ferry, which is even bigger with a length of 98 m, a width of 25 m, and can transport up to 399 passengers and 75 cars, is scheduled for delivery in 2021.

    So each ferry only has to make three times the number of trips to equal one trip of the other ferrys. It may cut omissions in that area. What about the omissions caused by extracting the lithium and other things? How much is emitted by supplying the electricity needed for those extra trips?

    The optics look good for them but probably look worse in other areas.
    But optics is all that counts right?

    Well, In Washington state, the vast majority of electrical power is from renewables;

    Washington - State Energy Profile Analysis - U.S. Energy Information Administration (EIA)

    Renewable energy
    Washington ranks second in the nation in electricity generation from renewable resources.

    Washington ranks second in the nation, after California, in the amount of electricity generated from renewable resources.53 On average, about 80% of the state's net electricity generation originates from renewable energy, mostly hydroelectric power, and Washington produced about one-eighth of the total electricity generated nationwide from renewables in 2017.54 Some renewable resources provide energy in forms other than electricity, such as biofuels and thermal energy from the wood used in wood stoves.55 When the production of those other types of energy is included, renewable resources account for 90% of Washington's total energy production.56 Washington has two wood pellet manufacturing plants with a total production capacity of about 80,000 tons per year.57
