Energy Storage and New Fuels Work Together as One on Vessels

The PCTC Grande Shanghai was commissioned by the Grimaldi Group from China Merchants Heavy Industries. The vessel integrates numerous green technologies: mega lithium batteries with a total power of 5 MWh, 2,500 square meters of solar panels, and cold ironing with shoreside supply of electricity where available.

There’s an obvious fuel saving advantage, but partnering energy storage systems with new fuels brings other advantages too.There’s a new generation of vessels emerging which is exemplified by Grimaldi’s PCTC Grande Shanghai, claimed to reduce fuel consumption by 50% compared to previous-generation car carriers, and the NCL Vestland, a container feeder vessel similarly claimed to reduce energy consumption per TEU per nautical mile by 63%.What these vessels have in common is a propulsion system that combines energy storage systems and new fuels.As Henrik Helgesen
