煤炭与新能源融合发展对我国能源转型和能源安全稳定供应具有重要的支撑作用。本文立足我国资源禀赋并考虑能源保供与转型需求，阐述了煤炭与新能源融合发展的重要意义，系统剖析了煤炭与新能源融合发展具备的基础条件。从煤炭开发，燃煤发电，煤化工，碳捕集、利用与封存（CCUS）分别与新能源融合的4个场景角度出发，总结了当前煤炭与新能源融合的主要形式、技术特征、应用情况等。着重关注煤炭开发与新能源融合、“风光火储”联合调度、太阳能光热与燃煤发电融合、太阳能光热与CCUS融合、绿氢与煤化工融合等5类技术，深入分析了煤炭与新能源融合技术体系的发展挑战与突破方向。研究建议，将煤炭与新能源融合发展上升为国家战略，系统推进煤炭与新能源融合发展，加大煤炭与新能源科技研发力度，完善煤炭与新能源融合发展相关的财政、金融和人才支持政策。
The integrated development of coal and new energy sources is crucial for the smooth transition of China's energy system and the security and stable supply of energy. Considering China's resource endowment and its demand for energy supply security and transformation, this study elaborates on the significance and fundamental conditions regarding the integrated development of coal and new energy sources. Moreover, it summarizes the major forms, technical characteristics, and application status of the integrated development from the aspects of four scenarios: integration of coal mining, coal-fired power generation, coal chemical industry, and carbon capture, utilization and storage (CCUS) with new energy sources. Emphasis is placed on five types of technologies: integration of coal development with new energy sources; combined dispatching of wind, solar, thermal, and storage; integration of solar thermal and coal-fired power generation; integration of solar thermal power generation with CCUS; and integration of green hydrogen with the coal chemical industry. Furthermore, this study explores the key technological challenges and breakthrough directions, and proposes the following suggestions: (1) incorporating the integrated development of coal and new energy sources into national strategies; (2) formulating action goals and roadmaps to systematically support the integrated development; (3) strengthening the research and development of technologies regarding coal and new energy sources; and (4) improving fiscal, financial, and talent support policies related to the integrated development.
