Most of the best innovations have been economically driven, and not policy driven.

The battery holds 4.1 megawatt hours, should pay for its self in about 8 years if fuel prices don't go up (ha!) and last at least 15 years.

The guy said 600 amps, so that would be 6 mW of charging. It would have to be that high if it's going to replace 75 kWh in 5-10 minutes of charging.
He also said the expected lifespan of the battery is 5 years.
The savings will accrue in lower maintenance costs as well as fuel saved.
It would be neat to see what is possible if a ship is purpose built as an EV rather than a retrofitted diesel series hybrid.
