压缩空气储能技术
压缩空气储能或压缩空气储能技术(Compressed air energy storage),简称CAES,是一种利用压缩空气来储能的技术。民生上,离峰时段的能量得以储存,并于高峰时段释放使用[1]。小型系统长期以来一直用于矿山机车之推进等应用。由于散热会降低存储系统的能源效率,因此放大应用必须针对压缩空气进行热量守恒控制。液态空气储能透过加压空气再冷却来液化空气,并储存能量。在学术研究中会将其归类为压缩空气储能的一种。[2]
种类
气体压缩会产生热,因此压缩后的空气温度较高。相反地,气体膨胀会释放热。如果没有额外的热量进入系统,空气温度在膨胀后会显著下降。如果能将压缩所产生的热储存起来,并于膨胀时释放,则储能效率便能显著提升[3]。CAES系统控制热量的方式主要分为绝热、非绝热或恒温等三类。
储存
恒温储存
恒压储存
热力学
为了提升储存与释放过程的效率,因此一般采用近似可逆的等温或等熵过程[3]。
