太平洋西北实验室评估了在Luz国际公司开发的太阳能发电系统（SEGS）发电厂使用化学储能的潜在可行性。与感热或潜热储能系统一样，化学储能可以有效地应用于太阳能热电厂，以抑制云瞬变的影响，延长日常运行周期，和/或允许在高价值的高峰需求期间产生更高比例的电力生产。更高的能量存储密度使化学能量存储成为一个潜在的有吸引力的选择。评价结果表明，基于可逆反应的体系CaO + H{sub 2}O = Ca(OH){sub 2}在技术和经济上是可行的，但仍需解决许多技术和经济问题。
The Pacific Northwest Laboratory evaluated the potential feasibility of using chemical energy storage at the Solar Electric Generating System (SEGS) power plants developed by Luz International. Like sensible or latent heat energy storage systems, chemical energy storage can be beneficially applied to solar thermal power plants to dampen the impact of cloud transients, extend the daily operating period, and/or allow a higher fraction of power production to occur during high-valued peak demand periods. Higher energy storage densities make chemical energy storage a potentially attractive option. The results of the evaluation indicated that a system based on the reversible reaction, CaO + H{sub 2}O = Ca(OH){sub 2}, could be technically and economically feasible for this application, but many technical and economic issues must be resolved.
