Siemens China carbon neutralization white paper provides route planning suggestions for the realization of carbon neutralization goals in key industries and shares global practical experience. As one of the important measures taken by Siemens China to implement the “zero carbon pioneer plan”, the white paper analyzes the carbon reduction challenges and opportunities in the fields of industry, transportation, construction and energy one by one, and provides Siemens consulting, solutions, innovative technologies and successful cases in these fields, so as to provide guidance for the green development of the industry.
The following is an excerpt from the white paper on architecture.

The transportation field focuses on pure / hybrid technology and traffic digital technology

Carbon emissions from transportation account for about 7% of the total, mainly from the direct combustion of fossil energy. With the continuous promotion of China’s urbanization, the energy demand and carbon emission in the field of transportation will show a significant growth trend.
Transportation – automobile

• There is an obvious gap between China’s per capita car ownership and the current situation of developed countries, and the demand for passenger cars will increase year by year in the future
• New energy passenger vehicles account for only 1.75% and new energy trucks account for only 0.9%, which will become the focus of future development
• There is still much room for optimization at the level of overall traffic planning and dispatching

Transportation – others (rail, air, water)

• Special fuel oil is still the main fuel for air and water transportation, and the fuel substitution technology is not yet mature

• The complexity of aircraft optimization is high. At present, it still depends on operation means to optimize the route
• The ship electrification technology environment is limited and only supports short-distance and light-weight transportation. The use of liquefied natural gas for long-distance freight transportation is the mainstream carbon reduction measure at present, and alternative fuels such as ammonia and hydrogen are not yet mature

Future emission reduction path in transportation

Policies guide and optimize the transformation of transportation industrial structure
Optimize the planning and design of transportation, guide the demand for transportation services, advocate sharing public transportation, reduce car ownership, reduce traffic congestion, improve urban traffic efficiency, expand the scope of traffic management system through digital means, and reduce transportation time, cost and emissions.
Improve vehicle efficiency and reduce fuel consumption of traditional fuel vehicles

Use hybrid technology and vehicle lightweight technology to reduce the overall fuel consumption and improve the effect of vehicle kinetic energy
Improve the energy consumption efficiency of rail transit system and reduce the carbon footprint of rail transit system
Use clean fuel
In the long run, transportation energy consumption should turn to electrification, diversification and cleaning, get rid of dependence on oil products, and realize decoupling from oil products and carbon emissions. We should continue to improve the stability of fuel cells and reduce costs, further strengthen the development and commercialization of biomass fuel, hydrogen energy and other related technologies, and strengthen the industrial coupling of clean energy.

Technology empowerment and emission reduction in transportation field

Reconstruction and upgrading of existing rail vehicles and systems
By applying the latest material technology, the original car body is transformed to reduce the level of energy consumption; Build a predictive maintenance system to improve the reliability and safety of train operation and the life cycle efficiency of traffic electromechanical equipment; Use advanced digital technology to save resource consumption during train operation and maintenance and promote low-carbon development.
Introduce hydrogen energy and train battery technology, use new energy power to replace traditional diesel locomotives, and promote energy conservation and emission reduction of rail transit. Establish digital simulation and monitoring application of power supply system, simulate and optimize the design of rail transit power supply system, promote the improvement of rail transit energy efficiency and reduce carbon emission level.
Introduce digital solutions to improve user experience, attract users to use public transport and reduce overall traffic carbon emissions
Apply intelligent technical means to optimize the driving traction and signal system of rail transit, and improve the operation efficiency and punctuality rate of urban rail transit. By creating intelligent applications, integrating the functions of travel planning, ticket booking and payment with big data analysis into a flexible and reliable platform, seamlessly integrating public transport and shared mobile services, improving the overall efficiency of passenger experience and transportation system, and reducing relevant carbon emissions.

Siemens best practices sharing

Shanghai Shentong Metro Group – automatic driving system for rail transit line 18
Siemens transportation cooperates deeply with Shanghai Shentong Metro Group Co., Ltd. to provide relevant components and services of traction system of fully autonomous vehicles, fully autonomous driving function design, interface design, vehicle circuit design, definition of safety integrated level (SIL), etc. for its rail transit line 18. SIEMENS’s mature fully automated driving system improves and ensures punctuality rate and ensures more efficient city rail transit operation.
Bozhong Seiko intelligent power station solution
Electric vehicles are environmentally friendly, energy-saving and comfortable to drive, but mileage anxiety has long been a major concern for consumers, affecting the development of new energy vehicles. Bozhong Seiko and Siemens work together to build a fully integrated automation system and digital intelligent power exchange station. The whole process takes only 2 minutes. The innovative remote debugging platform can effectively solve the maintenance problems of rapid growth in the number and scattered location of replacement power stations. By the middle of 2021, the power exchange stations delivered by Bozhong have been distributed in 21 provinces and municipalities directly under the central government, with a cumulative annual carbon emission savings of 15 million tons.
Deutsche Bahn – mireo plus, a new energy powered train platform
Siemens transportation accelerates the development and provides customers with the next generation hydrogen powered train platform mireo plus h and battery driven train platform mireo plus B, which use new energy power to replace traditional diesel locomotives and promote energy conservation and emission reduction of rail transit. At the same time, the recovery rate of this series of train platforms at the end of the life cycle is 95%. At present, Siemens transportation is also actively testing the newly developed next-generation hydrogen powered train mireo plus h and hydrogenation station with Deutsche Bahn, which is expected to be put into trial operation in Germany in 2024.
