煤炭制氢产业现状及我国新能源发展路径选择研究

摘要

This article analyzed the cost of mainstream hydrogen preparation technology first.Based on China's energy structure in the majority of coal,the characteristics of hydrogen preparation and different materials cost difference,pointed out that China should give preference to the preparation of coal to hydrogen.Besides,the energy density of the hydrogen fuel cell is greater than the lithium battery in electric cars.Hydrogen is an environmentally friendly energy that the reaction products from fuel cell is only water,also there is no pollution problem as lithium battery in life cycle end.The establishment of hydrogen society is a good opportunity to promote the transformation of China's coal industry.%本文首先对几种主要的氢气制备技术的成本进行了核算.基于中国的能源结构中煤炭占绝对多数的特点,以及不同原料制备氢气的成本差异,指出中国应优先选择煤炭作为氢气的制备的来源.另一方面,液氢的能量密度远大于动力锂电池电动汽车.氢燃料电池反应后产生的排放物只有水,是一种非常纯净的能源,亦不存在锂电池生命周期结束后的污染处理问题.建立氢社会是促进我国能源结构调整和煤炭工业转型的良好机遇.
