Life cycle analysis of batteries in maritime sector.

Batteries used in maritime sector is environmentally very good, according to a study conducted by Maritime Battery Forum.

The purpose of the study was to perform a life cycle assessment of batteries used in a maritime setting. Two cases have been considered: a hybrid platform supply vessel (PSV) and a fully electric ferry. The emissions considered in this study are greenhouse gases and NOx emissions.

The results shows that the environmental impact related to the production of battery systems are minimal compared to the savings achieved in operation. The battery systems, if designed properly, have an environmental payback time of only a few days up to 1.5 months.

Even with "dirty" power in the electricity supply, the battery systems are environmentally good technology compared to conventional diesel power.

The report has been prepared by the Maritime Battery Forum in cooperation with Grenland Energy, ABB, and DNV GL for the Norwegian NOx-fund.
