Achieving carbon peak and carbon neutrality is a tough battle. The ninth meeting of the Central Financial and Economic Commission held recently emphasized that my country strives to achieve carbon peak before 2030 and achieve carbon neutrality before 2060. This is a major strategic decision made by the Party Central Committee after careful consideration and is related to the sustainable development and construction of the Chinese nation. A community with a shared future for mankind.

How do you view the key tasks proposed at the meeting and what is the current progress? The "14th Five-Year Plan" is a critical period and a window period for carbon emissions to peak. How should the next step be to achieve green and low-carbon development? The reporter interviewed relevant departments and experts.

Accelerate the development and utilization of clean energy and build a new power system with new energy as the main body. The last unit of the Wudongde Hydropower Station was successfully hoisted, moving towards the goal of full-scale production of power generation. Two smart energy towns in Tianjin were built, and the proportion of clean energy utilization in the region can be achieved. Reaching 90%; the first electric work boat in the Taihu Lake Basin was launched, which can store electricity equivalent to the electricity of 5 electric cars... Recently, good news about the green and low-carbon development of energy has been spreading frequently, injecting sufficient momentum to achieve carbon peak and carbon neutrality. .

The Ninth Meeting of the Central Financial and Economic Commission pointed out that it is necessary to build a clean, low-carbon, safe and efficient energy system, control the total amount of fossil energy, strive to improve utilization efficiency, implement renewable energy substitution actions, deepen the reform of the power system, and build an energy system with new energy as the main body. New power system.

According to the relevant person in charge of the National Energy Administration, during the "13th Five-Year Plan" period, my country's installed capacity of hydropower, wind power, photovoltaics, and nuclear power under construction remained the first in the world; by the end of 2020, the installed capacity of clean energy power generation increased to 1.083 billion kilowatts. For the first time, the installed capacity of coal power exceeded that of coal power, accounting for approximately 49.2% of the total installed capacity, establishing a diversified and clean energy supply system.

Despite this, the task of reducing carbon emissions in the energy and power sector is still relatively heavy. Data show that energy combustion is the main source of carbon dioxide emissions in my country, accounting for about 88% of all carbon dioxide emissions, and emissions from the power industry account for about 41% of emissions from the energy industry.

The development of renewable energy is an important measure to promote energy transformation. In response to the "implementation of renewable energy substitution actions" mentioned at the meeting, the relevant person in charge of the National Energy Administration stated that they will promote the large-scale, high-proportion, market-oriented development of renewable energy and increase the proportion of renewable energy in energy and electricity consumption. Make renewable energy the mainstay of my country's primary energy consumption increase during the "14th Five-Year Plan" period.

The industry is also paying great attention to the idea of "building a new power system with new energy as the main body". "Wind power and photovoltaic power generation are volatile. In the future, with the rapid development of new energy and the widespread application of new energy-using equipment, the difficulty of balancing the supply and demand of the power system and ensuring safe and stable operation will increase accordingly. Therefore, a new power system must be built." State Grid said Lu Gang, director of the Institute of Energy Strategy and Planning of the Institute of Energy Research.

What does a new power system with new energy as the main body look like? According to the relevant person in charge of the National Energy Administration, the new power system is widely configured and applied with flexible adjustment resources such as new energy storage and electric vehicles, and can adapt to the grid-connected consumption of large-scale and high-proportion centralized and distributed renewable energy. In terms of structural characteristics, it is centered on the safety and reliability of the user side, and is characterized by high degree of digitalization and intelligence, coordinated interaction of sources, grids, loads and storage, multi-energy complementation of power, strong clean energy resource allocation capabilities, and flat dispatching operations.

Industry experts believe that building a new power system with new energy as the main body requires coordinated efforts from many aspects, especially accelerating the research and development and application of new energy storage technology, improving the multi-source coordinated and optimized operation capabilities on the power supply side, and promoting the comprehensive digitalization of all aspects of the power system.

In this regard, the relevant person in charge of the National Energy Administration stated that during the "14th Five-Year Plan" period, research will be guided to break through large-capacity, high-security, low-cost, high-efficiency, and long-life energy storage technologies, and the energy storage market participation and investment income mechanism will be improved. ; Give full play to the flexible adjustment capabilities of thermal power units, study and improve the compensation mechanism for active deep peak shaving and flexible transformation of thermal power units; accelerate the research and development and application of intelligent technology in the power system, based on emerging technologies such as artificial intelligence, big data, and cloud computing, Build a highly intelligent dispatching operation system.

Focus on upgrading energy consumption patterns and promoting pollution reduction and carbon reduction in key industries. The ninth meeting of the Central Financial and Economic Committee pointed out that actions to reduce pollution and carbon emissions in key industries should be implemented. Green manufacturing should be promoted in the industrial sector, energy-saving standards should be improved in the construction sector, and energy-saving standards should be improved in the transportation sector. It is necessary to accelerate the formation of green and low-carbon transportation methods.

"Improving energy efficiency and controlling total primary energy consumption are the most direct and effective ways to reduce energy carbon emissions. Under the current energy structure, reducing primary energy consumption by 100 million tons of standard coal can reduce carbon dioxide emissions by approximately 200 million tons." Lu Gang believes that building a clean, low-carbon, safe and efficient energy system requires walking on "two legs" and coordinating the changes in energy consumption patterns of clean and low-carbon energy supply and major energy-consuming industries such as industry, construction, and transportation.

As an industry with high energy consumption, the steel industry has the largest carbon emissions among the 31 manufacturing categories. At China Baowu Group Bayi Iron and Steel Co., Ltd., the hydrogen-rich carbon cycle blast furnace pilot project is stepping up construction. According to the person in charge of the company, from burning carbon to burning hydrogen, after the successful test of the project, it will not only greatly improve the utilization coefficient of the smelting furnace, but also reduce carbon dioxide emissions by 30%.

Not only the industrial sector, but also other key industries are also continuing to make efforts to reduce pollution and reduce carbon emissions.

In the field of construction, energy-saving renovations are being promoted in an orderly manner, prefabricated construction is being accelerated, and photovoltaic building integration is ready to go... The Ministry of Housing and Urban-Rural Development and other departments have issued plans that by 2022, the proportion of green building area in new urban buildings will reach 70%. .

In the field of transportation, since the end of 2015, my country has phased out more than 14 million old motor vehicles; currently, the proportion of new energy buses added and replaced in Beijing, Shanxi, Shanghai, Hunan and other places has reached 100%; according to estimates, the promotion of the transportation industry The application of new energy vehicles can reduce carbon emissions by approximately 50 million tons per year.
