On February 22, 2022, a 3,000-ton electric cargo ship jointly developed by State Grid Jiangsu Electric Power and relevant departments and enterprises was launched in Nanjing. This is currently the largest electric cargo ship in the Yangtze River Basin, which will accelerate the promotion of large bulk carriers. The electrification transformation will help the green and low-carbon transformation of Yangtze River shipping.
This 3,000-ton cargo ship is a new electric cargo ship converted from a fuel-fired ship. The two sets of removable batteries on the deck of the ship can store 2,200 kWh of electricity, which can be charged by the shore power at the dock. It can be fully charged in 3 hours and can travel more than 120 kilometers.
Feng Fusheng, chief engineer of the "Shiplink No. 1" electric cargo ship: Originally, when using oil, the annual fuel consumption was about 300 tons. If it is changed to electric, the annual power consumption will be about 600,000 kWh, and the operating cost will be reduced by nearly 60%.
Wang Wentian, deputy general manager of State Grid Jiangsu Nanjing Power Supply Company: In the field of large-capacity electric cargo ships, according to our research, there is no particularly mature technology at home and abroad. However, as we cooperate with relevant departments and enterprises to carry out technical research, the localization rate of core technologies has reached more than 90%.
The average tonnage of cargo ships in the Yangtze River basin is 2,500 tons. The successful development of this 3,000-ton electric cargo ship means that more than 80% of the Yangtze River cargo ships can be electrified, and the transformation time can be controlled within half a year.
Zhou Shening, Deputy Secretary-General of Jiangsu Shipbuilding Engineering Society: In 2022, on the basis of this ship's maiden voyage, we will continue to carry out the "oil-to-electricity" pilot program for similar short-haul large-tonnage transport ships to promote the formation of a series of standards for electric ship mooring and help inland shipping Green and low-carbon transition.Editor/Ma Xue
