摘　　要：在“3060碳达峰碳中和”双碳目标的大背景下,新能源装机容量将会大规模提升,但是由于光伏、风电等新能源具有输出不稳定、发电曲线与用电曲线不匹配等缺点,如果不搭配使用储能系统,可能会导致大规模的弃风、弃光;而在供蒸汽领域中,绝大部分依然采用燃煤、燃气等传统化石燃料,随着环保压力的加大,亟需寻找一种替代之法。熔盐储能材料具有流动性强、黏度低、蒸汽压低、热容量大、比热容高、导热能力强、性质稳定、使用温区广、经济性好等显著优势,在供蒸汽领域有广阔的应用前景。基于熔盐储能的特性,着重介绍了熔盐储能技术在新能源消纳及供蒸汽领域的发展前景。该技术具有环保低碳、节能减排、高效利用等优势,是储能技术未来的发展方向,值得今后大规模推广应用。Under the background of the dual carbon goal of"3060 peak carbon dioxide emissions and carbon neutrality",the installed capacity of new energy will increase on a large scale.However,due to the shortcomings of photovoltaic,wind power and other new energy sources such as unstable output and mismatch of power generation curve and power consumption curve,if the energy storage system is not used in combination,it may lead to large-scale abandonment of wind and solar energy;in the field of steam supply,most of the traditional fossil fuels such as coal and gas are still used,so it is urgent to find an alternative method with the increasing pressure of environmental protection.Molten salt energy storage materials have significant advantages such as strong fluidity,low viscosity,low steam pressure,large heat capacity,high specific heat capacity,strong thermal conductivity,stable properties,wide operating temperature range and good economy,and have broad application prospects in the field of steam supply.Based on the characteristics of molten salt energy storage,this paper emphatically introduced the development prospect of molten salt energy storage technology in the field of new energy consumption and steam supply.This technology has the advantages of environmental protection and low carbon,energy saving and emission reduction,and efficient utilization.It is the future development direction of energy storage technology and is worthy of large-scale promotion and application in future.
