Newport News – On this warm, bright December morning, Mitsui O.S.K. Lines’ (MOL) pure car carrier, EMERALD ACE, arrived at the Virginia Port Authority’s Newport News Marine Terminal to discharge imported Nissan and Infiniti vehicles manufactured in Japan. While her voyage was unremarkable, the vessel itself is.
EMERALD ACE was delivered in June 2012 by Mitsubishi Heavy Industries’ (MHI) shipyard in Kobe, Japan. Her completion culminated a collaborative design/build effort involving, MOL, MHI and Panasonic. That effort produced a vessel designed to achieve zero emissions in port through the use of onboard solar panels and a hybrid electric power supply utilizing lithium-ion batteries.
Although the vessel has a diesel generator, solar energy gathered while at sea and stored in the lithium-ion batteries, can be used in place of the traditional generator. Up to 2.2 megawatt hours, enough to power 160 single-family households for a day, can be stored in the vessel’s batteries. The reduction in carbon emissions while in port is significant.
The partnership to build the EMERALD ACE was supported by Japan’s Ministry of Land, Infrastructure, Transport and Tourism and Nippon Kaiji Kyokai (ClassNK).
