I am currently trying to define what the appropriate battery would be for a hybrid boat. I found information on Vanadium batteries, that apparently are close to commercialization. Their biggest drawback is apparently the low specific energy, but this is not very critical on a boat. I also read about Cerium that could provide a higher energy density.
Does someone know about these? What is their future? Are the claimed advantages of Vanadium batteries true?
In short, I would like to discuss the topic in all its aspects, including hazard and ecologic risk.
For those who have no documentation but are chemists - which i am not - I can supply them with information I got by writing to a company that is currently developing a vanadium battery.

From the technical point of view using vanadium battery on the boat
appear to be a good idea as specific energy is basically irrelevant.
But than why not use deep-cycle lead acid cells, as same argument
applies there.

Main issue with using vanadium flow battery in a boat is the possibility of a leak. Soluble vanadium salts are toxic and the chance of damping a ton of this solution into a picturesque bay killing all forms of life for years to come appears scary.
