Rapid declines in battery costs are accelerating the prospects for all-electric interregional container shipping. With a battery price of $ 100 per kWh, it will be profitable to introduce electric ships to service trade routes up to 1,500 km, say researchers from the Energy and Resources Group, University of California, Berkeley.
However, when the costs related to environmental degradation are taken into account, it may be justified to run services up to 5,000 km.
104 unique scenarios for vessel size and route length have been developed that can be compared to almost any container ship in operation today, report Kersey, Popovich and Phadke. They state: “Our results suggest that more than 40% of global container traffic could be electrified cost-effectively using current technology.”
