摘要
中国正力争在2030年达到碳排放峰值,并在2060年前实现碳中和。以可再生能源为主体的新型电力系统是实现这两个目标的必然选择。中国风力发电在过去十余年中快速发展,同时,风力发电机组的退役也成为一个重要的问题,而在研究领域引起的关注却很少。该文介绍了处理退役风电机组的三种方式,阐述了包括金属、永久磁铁、电缆、电线和叶片复合材料的风机材料回收的技术进展和未来趋势,且对2030-2060年通过风力发电机组回收节约的材料和能源进行了定量预测。预测结果表明,中国2030-2060年退役的风力发电机组中的碳纤维、铜、铝和钢的回收利用可以节约相当于7600万吨标准煤的能源使用,减少1.87亿吨二氧化碳排放。最后提出了促进风机回收的政策建议和技术发展方向。
China is striving to reach peak carbon emissions by 2030 and achieve carbon neutrality by 2060.A new type of power system based on renewable energy is a natural choice to achieve these two goals.China's wind power generation has grown rapidly over the past decades.At the same time,the decommissioning of wind turbines has become an important issue,while it has attracted little attention in the research field.This study presents three ways to handle retired wind turbines,describes the technological progress and future trends in wind turbine material recycling including metals,permanent magnets,cables,wires and blade composites,and makes quantitative projections of material and energy savings through wind turbine recycling from 2030 to 2060.The projections show that the recycling of carbon fiber,copper,aluminum and steel from retired wind turbines in China from 2030-2060 could save energy use equivalent to 76 million tons of standard coal and thus reduce 187 million tons of CO_(2) emissions.Finally,this paper proposes policy recommendations and technology development directions to promote wind turbine recycling.
