BATTERY POWER - WHAT FORM MIGHT FUTURE HYBRID SOLUTIONS TAKE?

摘要

Like the automotive industry, classification society DNV GL divides battery-powered ships into three types: 1. full-electric ships (ES) 2. plug-in hybrid ships (PHES) 3. hybrid ships (HES). On a full-electric ship, all the power for propulsion and auxiliaries would come from batteries. A plug-in hybrid ship, similar to a plug-in hybrid car, would be able to charge its batteries using shore power and has both conventional propulsion and electric propulsion. Such a ship can operate on batteries alone on specific parts of the route, when manoeuvring in port and during standby operations. A hybrid ship uses batteries to increase its performance and does not use shore power to charge its batteries.
