Abstract A potential enabler of a low carbon economy is the energy vector hydrogen. However, issues associated with hydrogen storage and distribution are currently a barrier for its implementation. Hence, other indirect storage media such as ammonia and methanol are currently being considered. Of these, ammonia is a carbon free carrier which offers high energy density; higher than compressed air. Hence, it is proposed that ammonia, with its established transportation network and high flexibility, could provide a practical next generation system for energy transportation, storage and use for power generation. Therefore, this review highlights previous influential studies and ongoing research to use this chemical as a viable energy vector for power applications, emphasizing the challenges that each of the reviewed technologies faces before implementation and commercial deployment is achieved at a larger scale. The review covers technologies such as ammonia in cycles either for power or CO2 removal, fuel cells, reciprocating engines, gas turbines and propulsion technologies, with emphasis on the challenges of using the molecule and current understanding of the fundamental combustion patterns of ammonia blends.

动力用氨

摘要 低碳经济的潜在推动者是能量载体氢。然而，与氢储存和分配相关的问题目前是其实施的障碍。因此，目前正在考虑其他间接存储介质，例如氨和甲醇。其中，氨是一种无碳载体，可提供高能量密度；高于压缩空气。因此，提出氨以其既定的运输网络和高度的灵活性，可以为能源运输、储存和发电使用提供实用的下一代系统。因此，这篇评论强调了以前有影响力的研究和正在进行的研究，以将这种化学物质用作电力应用的可行能量载体，强调每项审查的技术在实现更大规模的实施和商业部署之前面临的挑战。该评论涵盖了诸如用于动力或二氧化碳去除的循环中的氨、燃料电池、往复式发动机、燃气轮机和推进技术等技术，重点介绍了使用该分子的挑战以及目前对氨混合物基本燃烧模式的理解。
