Efficient and clean use of fossil energy under the "double carbon" goal

Development proposals for efficient and clean utilization of fossil energy under the "double carbon" goal

The efficient and clean utilization technology of fossil energy is the key to the transformation of the national energy structure, and is the key means and way to effectively support the realization of the "dual carbon" goal. In the context of the energy revolution and the new situation of the "double carbon" goal, vigorously develop the efficient and clean utilization of fossil energy technologies, promote the efficient combustion and transformation of coal, the efficient utilization of oil and gas, and the research and application of the "three wastes" treatment technology of coal chemical industry, and strengthen the coupling of the fuel and raw material properties of fossil resources, which is of great significance to achieve the transformation of the national energy structure.

5.1 Efficient coal combustion and low-carbon conversion technology

At this stage, coal is still the main body of energy in our country, technological change and innovation, technological transformation and tapping potential is the main focus of clean and efficient use of coal, the National Energy Administration issued the coal power unit transformation and upgrading implementation plan in the "three reform linkage" is the specific support policy. In order to realize the combination of coal utilization and breaking in the process of energy transformation under the goal of "dual carbon", it is necessary to vigorously develop the typical industrial process coal utilization reform technology suitable for carbon peak and carbon neutrality, strengthen the attributes of coal fuel and raw materials, improve the utilization level of coal stock, and promote the research and development and application of coal efficient and low-carbon technology in a safe and orderly manner. Under this objective and background, the Chinese Academy of Sciences has deployed the strategic pilot science and technology project (Class A) "Clean Coal Combustion and Low carbon utilization", aiming at the efficient and low carbon utilization of coal, strengthening the coupling utilization of coal fuel properties and raw material properties and equipment process strengthening as a means to strengthen the research and development of key technologies and engineering verification, and promoting technology engineering demonstration. To realize the reduction, low-carbon and clean utilization of coal, and provide technical support for building a safe, efficient, low-carbon and clean energy system.

Flexible peak regulation technology of coal-fired boiler. The rapid development of renewable energy generation has injected new vitality into the low-carbon transformation of China's energy system. Because of the fluctuation and intermittency of renewable power, it affects the safe and stable operation of power system. At present, there is no large-scale, low-cost, long-period advanced energy storage technology available, there is an urgent need for coal power deep flexible peak regulation technology to meet the needs of large-scale renewable energy access to the grid. Accelerate the development and application of deep flexible peak regulation technology, ultra-low load stable combustion technology, and efficient flexible power-heat dual supply technology for coal-fired boilers, so as to achieve deep peak regulation and rapid load change of boilers, and protect the high proportion of renewable energy power generation connected to the grid. In particular, after 2030, coal will gradually transition to basic energy and secure energy.
