"Renewal" is one of the major changes in the economy this year. The "renewal" of consumption scenarios, the "renewal" of basic equipment, and the "renewal" of cities continue to stimulate the vitality of China's economy and bring "renewal" to the people.
In Qingdao Port, Shandong Province, green energy is changing the way the port operates. It not only uses photovoltaic, wind energy and energy storage , but also uses green fuel for tugboats. The first hydrogen-electric tugboat in China is carrying out its mission here. During the
port operation, the
annual throughput exceeded 700 million tons
. At the operation site of Qingdao Port Container Terminal in Shandong Province, the reporter was on the deck of a ship, which was the first hydrogen-electric tugboat in China just put into use in June this year. Reporters learned from Qingdao Port that this year, the port's cargo throughput has exceeded 700 million tons, of which the container throughput has also exceeded 30 million standard containers. These data can not be separated from the hard work of port workers, but also from the support of new energy and new technology. The hydrogen-electric tugboat with more than 12 hours
of
endurance is equipped with a hybrid system of "hydrogen fuel cell + liquid-cooled lithium battery", which can hardly feel the vibration and roar of the engine on the spot, and can last more than 12 hours at 9 knots of speed. Compared with traditional fuel tugs, it has significant advantages in equipment life and energy utilization, and is expected to reduce carbon dioxide emissions by more than 1500 tons per year. In addition, the cab adopts a split double-island layout, which not only provides better driving vision, but also facilitates the operation of various equipment, as well as Beidou satellite navigation system and intelligent shore-based charging system, filling many gaps in China.
In addition to tugboats, Qingdao Port has integrated solar and wind power generation and energy storage systems since this year, and has built and put into use an integrated charging area in the port area. The annual power generation of the port photovoltaic project is about 25 million kilowatt-hours, the application rate of new energy for operating vehicles is nearly 80%, and the proportion of clean energy in the port is 69%, which can reduce carbon dioxide emissions by about 20000 tons per year. I believe that in the future, with the support of new energy and new technologies, there will be more surprises and expectations for the construction of green ports.
