摘　　要：氨,作为零碳燃料和氢能载体,对于实现“双碳”目标和构建“氢能社会”具有重要意义。传统的地面钢储罐储氨方式能耗高、占地、风险高。本文提出一种新型的储氨方案,即利用地下废弃盐穴进行氨储存。这种方案利用氨气极易溶于水的特性,实现了氨的大规模稳定储存。由于储存氨的空间位于地下几百至上千米深度,地面占地少,氨气泄露和爆炸的风险小。本文详细分析了这种储氨方案的理论基础,并对其储能规模、安全性和经济性进行了评估。结果表明,这种储氨方案具有很大的应用前景,值得进一步研究和推广。Ammonia,as a zero-carbon fuel and hydrogen energy carrier,is of great significance for realizing the"two-carbon"goal and building a“hydrogen society”.The traditional surface steel storage tank for ammonia storage has high energy consumption,high land area and high risk.In this paper,a new ammonia storage scheme is proposed,that is,the use of underground abandoned salt caverns for ammonia storage.This solution takes advantage of the fact that ammonia is highly soluble in water and achieves large-scale stable storage of ammonia.Because the ammonia storage space is hundreds to kilometers underground,the surface area is small,and the risk of ammonia leakage and explosion is small.In this paper,the theoretical basis of this ammonia storage scheme is analyzed in detail,and its energy storage scale,safety and economy are evaluated.The results show that this ammonia storage scheme has great application prospects and is worthy of further study and popularization.
