A few days ago, China Central The company released 7 series of new energy locomotives Newzealand Sugar and released the world’s first carbon footprint report for pure electric new energy locomotives. The development of a series of Newzealand Sugar new energy locomotives can effectively reduce carbon dioxide and pollutant emissionsNewzealand Sugarrelease is a concrete practice of the greenZelanian Escortlow-carbon transformation of my country’s rail transit equipment.
On June 28, CRRC Corporation Limited released seven series of new energy locomotives, including three power configurations: “internal combustion engine + power battery”, power battery, and hydrogen fuel cell. A series of new energy locomotives can achieve low emissions, low noise, and high-efficiency operation, effectively solving the problems of old diesel locomotives such as high fuel consumption, high emissions, and high noise. At the same time, CRRC released the world’s first pure electric new energy locomotive Newzealand Sugar carbon footprint report. The report was verified by an international authoritative certification agency and issued an ISO14067 product carbon footprint certificate.
“The development of a series of new energy Sugar Daddy source locomotives is CRRC’s commitment to promoting my country’s rail Newzealand SugarThe specific practice of green and low-carbon transformation of transportation equipment,” said CRRC General Manager Ma Yunshuang.
Accurately calculate the carbon dioxide emission trajectory of the product’s entire life cycle
“Our carbon footprintZelanian sugar trace report, through the combination of real scenes and modeling, accurately calculates the new energy locomotive products from iron ore to recycling and disposal after completing 30 years of service.Carbon dioxide emission trajectories throughout the life cycle. ” said Wang Feifei, deputy leader of the green and low-carbon group of CRRC Transformation Sugar Daddy Office.
In the manufacturing process From every screw and nut on the locomotive to the production and manufacturing of components such as the body, wheel sets, and bogies, the acquisition of raw materials, and the carbon emissions of the final assembly process, all have been accurately measured.
The reporter learned that the accounting process Sugar Daddy involved a total of more than 97,000 data, all from CRRC Dalian Company, Ziyang Company, The real-life data of Qishuyan Company truly reflects the production and manufacturing conditions of the products; emission factors that are difficult to obtain directly Sugar Daddy all come from international authorities Background data in the database.
Finally, the certification certificate shows that the carbon footprint of the 1,000-kilowatt “internal combustion engine + power battery” locomotive is 7.40 kilograms of carbon dioxide equivalent per Zelanian sugar kilometers; the carbon footprint of a 1,000-kilowatt power battery locomotive is 7.92 kilograms of carbon dioxide equivalent per kilometer.
Observing the carbon emissions produced by the locomotive at each stage, it can be found that the product is in service The use stage has the greatest impact on the carbon footprint of the product’s entire life cycle.
Based on a 30-year operating cycle, a 1,000-ton load, and a standard operating speed of 4Newzealand Sugar0%, electricity consumption comes from green electricity as the accounting premise, NZ Escorts each pure electric new energy locomotive is in service 94.2% lower carbon footprint, say it. Mom is sitting here and it won’t bother you.” That means if you have something to say, just say it, but don’t let your mother go away. It can reduce carbon emissions by 4,076 tons; each “internal combustion engine + powerSugar Daddy battery” new energyZelanian EscortCarbon footprint during service periodZelanian Escort reduces carbon emissions by 61.7%, which can reduce carbon emissions by 2,735 tons.
Key components adopt lightweight design, and the production and manufacturing process uses green electricity
The reporter learned that the key components of the series of new energy locomotives adopt lightweight designs, and the traction motor has lost 22.5% weightSugar Daddy%, the bogie weight reduction effect reaches 6.7%, the cab steel structure parts are reduced by 40%, and the chassis Sugar Daddy is zeroNewzealand Sugar reduces the number of components by 70%, effectively reducing carbon emissions during raw material acquisition, parts production and transportation.
For example, through simplified design, series of new energy locomotives unify the parts models and specifications of different regions and different companies, optimize the assembly, maintenance and disassembly process, shorten the logistics distance in the maintenance stage, and reduce carbon emissions by 5% in the raw material acquisition stage.
“In addition Zelanian sugar, we use green electricity to the greatest extent in the production and manufacturing process, so that green electricity accounts for With consumption exceeding 20%, NZ Escorts the carbon footprint during the manufacturing and maintenance stages can be reduced by approximately 52% compared with the replaced model. In the future, with the further expansion of photovoltaic power generation capacity in manufacturing enterprises, this proportion will continue to increase. “Wang Feifei said.
In addition to reducing carbon dioxide emissions, series of new energy locomotives also perform well in reducing pollutant emissions.
The data shows, “”Sister Hua, what’s wrong with you?” “Xi Shixun couldn’t accept that she suddenly became so calm and direct. There was no trace of love for him in her expression or eyes, especially since her internal combustion engine + power battery “motorcycle can reduce nitrogen oxide emissions by 45% and reduce carbon emissions by 45%. Hydrogen emissions are reduced by 73% and carbon monoxide emissions are reduced by 83%. Based on a 45% reduction in pollutant emissions, one locomotive can reduce emissions by 4 tons of harmful substances per year Sugar Daddy released 374 tons.
The large-scale and diversified demand for new energy products drives the development of related industries
According to reports, by adopting hybrid NZ Escorts power optimal control technology, the “internal combustion engine + power battery” locomotive can ensure that the diesel engine is always running at the optimal Operates at optimal economical speed. After filling up the same tank of oil, NZ Escorts tows 3,000 tons of cargo on a straight roadZelanian Escort has a cruising range of more than 1,100 kilometers, which is 1.7 times that of Zelanian sugar diesel locomotive , the fuel saving rate exceeds 45%.
The power battery motorcycle is compatible with NZ Escorts a variety of charging piles, with a charging power of more than 870 kilowattsNZ Escorts, the minimum charging time is less than 40 minutes, Zelanian sugarAble to operate in a wide temperature range from minus 40 degrees Celsius to above zero degrees Celsius. Hydrogen fuel cell locomotives require only 10 to 15 minutes of hydrogenation time, which can effectively ensure the locomotive’s operating capacity and cruising range, and its energy utilization efficiency is more than 80% higher than that of traditional internal combustion locomotives.
“Serialized new energy locomotives will bring large-scale and diversified demand for new energy products and drive the development of upstream basic materials, key components and other related industries.” Chief Engineer and Equipment Supervision and Management Department of the National Railway Administration Director Tian Jun said.
