Environmental trends in shipping - opportunities for next generation energy storage and conversion technologies

Reduction of fuel consumption is a permanent research goal in all kinds of transportation. Moreover, in the last decade marine transportation is strongly influenced by the new regulatory framework for marine pollution that motivates investigation of alternative powering options for ships, offering lower emissions and lifetime costs. This work analyses current regulations on ship emissions associated with long term emission reduction goals, mathematical models to evaluate ship energy efficiency as well as technical and operative measures to meet ever stricter requirements [1, 2]. Mathematical models for life-cycle assessments (LCAs) of ship emissions and life-cycle cost assessments (LCCAs) are applied for several ships operating in coastal waters and inland waterways that are powered by alternative fuels and with different power system configurations [3, 4]. Electrification of ships is recognized as a promising option to reduce both lifetime emissions and total lifetime costs. However, additional research efforts are needed to make energy storage (batteries) and conversion technologies cheaper and applicable to long-distance shipping.
