Energy density of batteries is much lower than that of fossil fuels. Which means that the weight of the ships would increase. In addition to the high price of the batteries, potential risks of electrocution, etc.

There are intermediate options. Moving away from diesel towards natural gas would dramatically reduce emissions (including sulfur emissions), while retaining high energy density.

Electric is an immediate option. Norway has 80 electric ferries in service. https://businessnorway.com/articles/norway-showcases-award-w...

It may be an immediate option for places that have a very strong desire to reduce carbon emissions, but for profit-driven entities the push towards natural gas ends up as both more economical and more ecological.
