Abstract

In recent years there has been a palpable shift towards the electrification of propulsion systems for commercial and naval ships, permitting improved design flexibility, operational efficiency and potential through-life fuel saving benefits. The drive for increased performance and emissions reduction, coupled with increasing load variability provides opportunities for energy storage systems (ESS). Larger scale electrical ESS (beyond dedicated back up supplies) can introduce a number of key benefits to ships. With the quickly evolving landscape of ESS, driven by parallel industries, it would appear that the dominant forms of ESS will be batteries, flywheels and super-capacitors. Pertinent in using ESS, is to facilitate prime mover operation within its most efficient operating envelope with the ESS providing take-in take-out power to maintain constant loading of the prime-mover eliminating transients and thereby optimised to reduce fuel consumption. This paper will consider the state of the art of ESS in ships and its future direction. The characteristics of the ESS devices and their applications for commercial and naval ships will be examined with a comparison of the challenges and implications of ESS, identifying common issues for the naval and commercial sectors by way of case studies. The paper concludes with the outlook for integrating ESS with future ships.
