主な電気設備●太陽光発電システム「HITダブル」●リチウムイオン蓄電システムJune 2012 saw the completion of a hybrid car carrier vessel named “EMERALD ACE,” a joint development project by Mitsui O.S.K. Lines, Mitsubishi Heavy Indus-tries and Panasonic. This ship incorporates an onboard hybrid electric power supply system that consists of solar modules (160kW) and lithium-ion batteries (2.2MWh). When the ship is underway, the power generated by the PV system is stored in the lithium-ion batteries. While anchored, the ship’s onboard electric-ity requirements are accommodated solely by the solar module-generated power and battery-stored power, aiming for zero carbon emissions in harbor. The PV system installed in the vessel employs Panasonic's bifacial solar modules with maximum power of 210W, which can generate electricity from both sides of the modules because of solar cells sand-wiched between reinforced glass. The solar modules are also resistant to salt corrosion and wind pressure. Lithium-ion cell modules are located at the bottom of the ship so they can serve as fixed ballast to stabilize the vessel. To maintain the safety of batteries, battery modules are separated from each other by a nonflam-mable partition and observed by the storage battery monitoring system.
