Realization of Hybrid Electric Distribution System — “EMERALD ACE” World’s First Hybrid Car Carrier which Can Realize Zero Emission at Berthing Using Solar Power Generation System and Lithium Ion Batteries

Abstract

 The Emerald Ace was built as world’s first newly built hybrid car carrier, and is equipped with a hybrid electric power supply system that combines a 160kW solar generation system with lithium-ion batteries that can store some 2.2MWh of electricity. On the Emerald Ace, electricity is generated by the solar power generation system while the vessel is under way and stored in the lithium-ion batteries. The lithium-ion batteries can supply the electric power which the vessel required and the diesel-powered generator can be completely shut down during rest in port, resulting in zero emissions.
