The Emerald Ace is a car carrier . The ship, which is powered by diesel engines, is equipped with a battery system; the electrical supply is also provided by solar cells. The ship is currently considered the most environmentally friendly car transporter in the world.
description
The Emerald Ace was developed as part of a research project in Japan . The ship was designed for the Mitsui OSK Lines shipping company and built under construction number 1296 by the Japanese shipyard Mitsubishi Heavy Industries (MHI) in Kobe , Japan . The keel of the ship was laid on December 14, 2010, the launching on March 9, 2012. The ship was completed on June 29, 2012.
The ship is investigating the extent to which solar cells with integrated lithium-ion batteries can serve as a storage system for electrical energy. An important goal of enabling "zero- emission operation" in the port was achieved with this prototype.
This hybrid power supply was implemented in the research project "Development of Technologies for the Reduction of CO 2 Emissions from New Ships" and is now being examined in operation. The project is funded by the Japanese Ministry of Land, Infrastructure, Transport and Tourism and scientifically supported by Nippon Kaiji Kyōkai , the Japanese classification society .
The hybrid power supply of the Emerald Ace is equipped with 768 solar modules with a total output of 160 kW and includes lithium-ion batteries with around 2.2 MWh. The lithium-ion batteries are primarily used to prevent exhaust emissions from being emitted when berthing in port or in roadsteads . During the idle time, the solar cells and the batteries take over the power supply, the diesel generators are switched off. The lithium-ion batteries are located in the lower part of the ship and, due to their weight, also act as ballast .
environment
For over twenty years, the shipping industry has been working to make ships more environmentally friendly. In order to avoid competitive disadvantages for ships in global competition, the shipping countries have joined forces in the IMO . This is where the globally applicable regulations on ship safety, but also on environmental protection, are negotiated, resolved and ratified by the governments. They come into force when a specified number of the shipping countries have ratified the new regulations, but only if they exceed a specified number of ships or measurements.
