我国新能源发展已由单一技术规模扩张转向多技术集成融合发展阶段。随着供热(制冷)纳入可再生能源非电消费统计体系,新能源利用正由电力领域进一步向终端供热领域延伸。热泵作为连接新能源利用与终端供热的重要技术载体,可从空气、地热、再生水和工业余热等低品位热源中高效提取热量,替代传统化石能源供热,是推动新能源多元化利用的重要技术路径。
新能源供热规模化发展不仅需要技术进步,更需要目标引导、资源统筹、系统协同和质量保障等制度支撑。本文以北京为例,梳理其推动新能源供热规模化发展,形成以热泵为主体、多元热源协同发展的新能源供热格局的实践经验。在此基础上,本文进一步探讨完善可再生能源非电消费核算制度、建立长期低碳转型导向的发展路径、推动热力系统与电力系统协同规划等关键议题。
China’s renewable energy development has shifted from the large-scale deployment of individual technologies toward a stage of integrated, multi-technology development. The inclusion of renewable heating and cooling in the accounting framework for renewable non-electric energy consumption marks an expansion of renewable energy use beyond the power sector and into end-use heating. As a key technology linking renewable energy utilization with end-use heating, heat pumps can extract heat from low-grade sources such as ambient air, geothermal resources, reclaimed water, and industrial waste heat. By delivering heating with high efficiency, they can replace conventional fossil fuel-based heating and represent an important pathway for diversifying renewable energy use.
The large-scale deployment of renewable heating requires not only technological advancement, but also institutional support in the form of clear targets, resource coordination, system integration, and quality assurance. This paper reviews Beijing’s experience in scaling up renewable heating and establishing a system centered on heat pumps with coordinated utilization of multiple heat sources. This paper further explores key issues including improving accounting methodologies for renewable non-electric energy consumption, establishing long-term pathways for low-carbon transition, and promoting coordinated planning between heating and power systems.
