Description: Batteries in Shipping have been common elements of onboard systems/machinery layouts. They have had however a support role in starting-power to emergency systems, safety equipment, communication and other less energy/ power demanding solutions. The challenge is today to ensure, with batteries, the necessary power for heavy duty onboard power requirement such as propulsion and energy to diverse auxiliary systems throughout the ship operational profile. This would be provided by traction batteries. Different roles can today be played by battery systems onboard ships, with a more or less central relevance in the overall ship’s system design architecture. It is the objective of the present study to address this in the different perspectives of battery systems’ integration onboard ships, exploring the advantages and disadvantages, opportunities and main challenges for an increasingly ambitious role for battery systems in ships.
The above distinction between support and traction batteries is today a fundamental consideration when designing battery systems for ships, other electric vehicles or power machinery. Whilst support batteries will continuously play their role adequately and efficiently, traction batteries are considered a key enabling technology in electric vehicle (EV) technology development. Current traction batteries are to a large extent based on lithium-ion (Li-ion) chemistry, however in the future other lithium (Li) and non-Li based chemistries are expected to gain ground. The present study looks at the different battery technologies and proposes a prospective view up to 2050 of which are the likely technologies with the strongest potential for the shipping sector.
The present report provides a technical study on the use of Batteries in shipping that, being supported by a technology overview and risk-based analysis, will evaluate their potential and constraints as prime movers and energy sources in shipping. In addition, the study shall provide a detailed description of the current applicable standards, as well as the existing and potentially on-going regulatory development for Batteries, at both national and international level. From the evaluation of the current regulatory and standardization context a gap analysis shall be performed, with the objective of identifying regulatory, harmonization and relevant knowledge gaps. The proposed study shall, in particular, be able to link with the previous EMSA study on the use of Fuel Cells in shipping, identifying the possible routes for viable “all- electric” ships under the adoption of hybrid FC-Battery energy production/storage solutions.
