摘要
我国供热领域面临能源结构调整及严峻的环境污染等问题,氢能作为高效清洁的二次能源,具有燃烧热值高、燃烧产物无污染的特点,每千克氢燃烧后释放的热能,约为等质量汽油的3倍、酒精的3.9倍、焦炭的4.5倍。本文通过分析氢能在各领域利用及其发展概况,归纳现阶段氢能在供热领域的应用实例,以确定其可行性及发展前景。最后,本文从技术可行性,成本及碳排放情况对主流制氢技术进行了详细的分析对比,探讨了近中期和未来我国氢能的发展方向。
Chinese heating field is facing the problems of energy structure adjustment and severe environmental pollution.Hydrogen energy,as an efficient and clean secondary energy,has the characteristics of high combustion calorific value and pollution-free combustion products.The heat energy released after burning hydrogen per kilogram is about 3 times of that of gasoline,3.9 times of that of alcohol and 4.5 times of that of coke.This paper analyzes the utilization and development of hydrogen energy in various fields,summarizes the application examples of hydrogen energy in the field of heating at present,so as to determine its feasibility and development prospects.Finally,this paper makes a detailed analysis and comparison of the mainstream hydrogen production technologies from the aspects of technical feasibility,cost and carbon emission,and discusses the development direction of hydrogen energy in China in the near,medium and future.
