cross-energy integration

Pay Attention to the Green Development Effect of “Cross-Energy Integration”

Transportation and energy sectors are major carbon emitters, and their green and low-carbon development level has an important impact on the effect of energy conservation and carbon reduction. At present, with the gradual improvement of technology application scenarios and infrastructure guarantee level in the two fields, the trend of integrated development of transportation and energy has further emerged, new business forms and new models continue to emerge, and resource allocation methods and paths in line with the characteristics of industry development have initially taken shape. The integration of capital, technology, talents and data has generated strong economic and social benefits. Energy fusion has become a necessary and inevitable choice to break the constraints of resources and environment and improve the efficiency of resource utilization.

The key of cross-energy integration is that the two take energy saving as the common goal, and produce synergistic effect through fusion, and realize the complementarity of energy saving and carbon reduction. There are many links in the layout and construction design of transportation infrastructure. In the process of promoting the continuous improvement and upgrading of transportation infrastructure, the introduction of energy-saving technologies and the continuous improvement of the carbon reduction level of highways, ports, rail transit, ships and waterways will help to achieve a substantial increase in carbon emission efficiency in these fields.

From the perspective of energy network construction, the effective combination and mutual promotion of smart grid and transportation infrastructure network is an application scenario with strong demand, and the new model and new business form spawned by this effectively integrate resources in different fields to help the integrated development of energy. In recent years, China has continued to promote the integrated development of the transport sector and the energy sector. On the premise of fully considering the characteristics of China’s energy distribution and transportation construction, China has made overall planning and construction of new energy facilities, and integrated the concept of co-construction and sharing into energy infrastructure. A benign pattern of accelerating the layout of China’s energy integration and multi-point breakthroughs is taking shape.

Data show that at present in China’s energy consumption structure, transportation energy accounted for about 17%, and in the transportation energy structure, electricity accounted for less than 5%, the proportion of green electricity is less than 2%, in addition, in China’s carbon emission structure, the transportation sector carbon emissions accounted for about 10.4%. Therefore, combined with the current construction status and energy use structure in China’s transportation field, promoting green energy replacement in typical scenarios such as railways, highways, rail transit, ports, etc., can effectively play the role of local replacement of new energy. Taking the application scenario of the road field as an example, there are currently about 180,000 kilometers of toll roads in China, and under the circumstances of differences such as the available width on both sides of the road, bridge and tunnel ratio, and vegetation coverage, it is expected that the photovoltaic potential that can be developed can reach about 100 million kilowatts, and the large-scale development of the related industrial chain supply chain driven by this is a huge space.

Promoting the development of energy integration focuses on doing a good job in the “integration” article, and the focus is mainly in four aspects.

First of all, we need to strengthen the deep integration of smart transportation and energy management. Make good systematic planning and design, make full use of above – and underground space resources, accelerate the construction of hydrogen energy centers, cold chain storage and logistics and other infrastructure, further enrich the types of clean energy, and better and faster promote the integrated development of energy.

Secondly, it is necessary to do a good job of organic coordination between transportation energy and power grid energy supply. Under the premise of fully considering the distribution law, operation characteristics and energy consumption characteristics of transportation, strengthen the organic connection between the smart transportation network and the smart grid, take into account the energy consumption needs of passenger vehicles with “multiple points and wide areas” and commercial vehicles with “large volume concentration”, continue to improve the synergy efficiency of the “two networks” of the transportation network and the power grid, and constantly improve the integrated development efficiency.

Third, we should do a good job in the development of key technologies. Increase the research and development of key technologies and equipment in the field of energy integration, focus on key technologies such as new energy development in special scenarios, green energy supply planning and design, grid-connected transmission and multi-energy transformation, and develop core equipment such as efficient conversion of electric and cold hydrogen, multi-network integration and intelligent operation, so as to provide strong technical support for the development of energy integration industry chain.

Finally, it is necessary to actively summarize the successful scene application experience. The richness and perfection of application scenarios have an extremely important guiding and reference role for the in-depth development of AC energy fusion. From this perspective, the previous practical exploration of various places is a valuable wealth, and the good use and promotion of these experiences and practices are conducive to more efficiently guiding all kinds of high-quality resources to the field of energy integration and improving the efficiency of resource allocation. A platform can be built to promote the exchange of experience, while further finding the key links in need of support, giving precise assistance, and promoting the deep integration of energy.
