Container trucks shuttle through the port, gathering and dispersing goods all over the world. The reporter came to Tianjin Port radiating the three northern regions and found that with the continuous record high cargo throughput, the carbon emission intensity did not rise but fell, drawing a different "carbon content" change curve. Smelling "carbon content" According to a paper by the water transport Research Institute of the Ministry of transport, as the transfer node of the global supply chain, the greenhouse gas emissions of ports account for about 3% of the global greenhouse gas emissions. "In the past, which of the shore bridges, rail bridges and trucks used for loading and unloading did not burn oil and which was not a major carbon emitter." Tianjin Port truck driver he Zhencai said. However, this situation is turning around. A chart of Tianjin port that studies the intensity of carbon emissions since 2012 shows that a red line twists and turns, reflecting the increase of cargo throughput of Tianjin port in recent 10 years; The other blue line fell steadily, representing a steady decline in the carbon emission intensity of Tianjin port. The carbon emission intensity of a port is one of the important indicators to observe the green transformation of a port. "Since 2012, the cargo throughput of Tianjin Port has increased by 12%, the container throughput has increased by 64%, and the carbon emission intensity has decreased by 16%." Chen Yanping, deputy general manager of science and information facilities department of Tianjin Port Group, said. Looking at the whole Tianjin port, there are fewer and fewer "carbon emission" links: traditional thermal power is gradually replaced by green power, and the green energy system built in the port reduces carbon dioxide emissions by about 20000 tons per year; Fuel container trucks will be gradually "retired", and intelligent transportation robots and electric trucks will work, which can reduce 279 tons of fuel consumption and 865 tons of carbon emissions per month; The transfer of outward transportation roads to railways has reduced the use of fuel oil by 236000 tons every year. "In the past, when you walked around Tianjin port, you could smell a smell of diesel in smog days, and the sea breeze could not blow away. Now the air in the port area has become fresh." Chen Yanping said. Visible technology "gold content" Behind the reduction of "carbon content" is the launch of "black technology" in the port. Here is the "green engine": the world's first zero carbon wharf smart green energy system, which ensures zero carbon dioxide emission in energy production and consumption through new energy technologies such as wind power and photovoltaic. There is a "green transport team": a new generation of intelligent horizontal transport robots have become an intelligent driver who "sees all the way and listens all the way" by carrying a variety of sensors such as lidar, visual camera and millimeter wave radar. Beidou satellite reference station is built at the wharf with a coastline of 1100 meters to realize dynamic centimeter level high-precision positioning with the cooperation of 5g technology. "If there is an urgent task, robots can coordinate the order of 'filling up', which is better than the fuel truck driven by people." Said Liu Xiwang, deputy manager of the Information Department of Tianjin Port second container terminal Co., Ltd. Here is the "smart brain": the first intelligent horizontal transportation system connects key wharf equipment such as field bridge and shore bridge in series to realize the real-time information interaction of all production factors. "Production efficiency is improved, ships spend less time in port, and carbon emissions are reduced." Chen Yanping said. This port "makes coal but does not see coal". As an important coal launching port in northern China, Tianjin port takes the lead in realizing coal railway port transportation among ports in the country. Tianjin port also realizes 100% railway transportation of coal and coke, reducing vehicle exhaust emission and dust pollution. "In this process, Tianjin Port has realized the intelligent remote centralized control of equipment such as bulk cargo terminal dumper, intelligent on-line monitoring of belt conveyor and remote intelligent watering and dust suppression control." Wang Zhili, environmental protection management manager of the safety and environmental protection department of Tianjin Port Group, said. How far is it from zero carbon wharf to zero carbon port and zero carbon port? In the "14th five year plan" of Tianjin port, zero carbon port area and zero carbon port appear on the paper: The huge ship with full cargo slowly docked, and under the command of the remote intelligent dispatching center, the automatic shore bridge and track bridge lined up to receive instructions and run quickly; The driverless intelligent robot can walk freely in the yard. The standing fan rotates slowly to transmit clean electric energy for port production From zero carbon wharf to zero carbon port area and zero carbon port, Tianjin Port "reduces carbon" step by step. —— Tianjin port is deploying a comprehensive energy management and control platform covering more than 1400 points. "A platform to master the monitoring, management, optimization and early warning of key energy elements such as water, electricity, oil and gas." Wang Zhili said, "realizing the dynamic control of energy consumption and carbon emissions also points out the direction for subsequent carbon reduction." —— The phase II green energy system of section C Wharf in Beijiang port area is under construction and is expected to be put into use in October this year. "Ensure that the green energy system can meet the energy consumption requirements required for production with increased throughput." Chen Yanping said. —— Tianjin Port has formulated a clean plan for port horizontal transportation equipment, which will be replaced with clean energy equipment such as electric power and hydrogen energy in the future; During the berthing period of ocean going ships, all shore power will be used, and the production and operation in the port area will achieve zero carbon. —— Tianjin port also continues to strengthen the development of green energy, focusing on promoting the construction of centralized wind power of breakwater and distributed wind power and photovoltaic power generation system in the port area. In the future, the new green energy in the port area will not only provide energy guarantee for the construction of zero carbon port and zero carbon port, but also benefit the surrounding enterprises and people.
