Abstract
With the continuous optimization of energy structure,the advantages of high storage efficiency,environmental protection,and flexible application of liquefied natural gas(LNG)have gradually become prominent,becoming an important backup gas source in multiple cities,therefore,the number of LNG receiving stations is increasing day by day.During LNG gasification,a large amount of cold energy is released,which can be widely used in industries such as air separation,low-temperature refrigeration,and chemical production,if not properly utilized,it will cause great waste of cold energy,currently,various LNG cold energy utilization technologies have been developed both domestically and internationally.Hydrogen energy is a clean secondary energy source that can effectively connect energy fields such as natural gas and electricity,increasing the flexibility of future energy system operations.Under the goal of carbon peak and carbon neutrality(referred to as dual carbon),this paper analyzes the energy-saving advantages of hydrogen energy and LNG cold energy in hydrogen production,storage,and transportation,and looks forward to the prospects of joint development between hydrogen and LNG receiving stations.关键词
