Abstract. This chapter discusses the state of the art in chemical energy storage, defined as the utilization of chemical species or materials from which energy can be extracted immediately or latently through the process of physical sorption, chemical sorption, intercalation, electrochemical, or chemical transformation.
Applying these two savings to our cost model reduces the processing cost by $6/kg (or 6/25 = 24%). The projected price at high volume is 76% of the low-volume T700S price (or $26/kg x 76% = $20/kg) as shown at the right in Figure 2. Figure 2.
Hydroxide and carbonate TCES systems, which suffer from high sensible heat storage unit cost and high compression cost, respectively, have the medium and highest gas storage costs. Faster reactions do not only reduce reactor costs because of shorter reactor residence time, but also improve η s - e due to smaller T R 1 - T eq and T

In chemical energy storage, energy is absorbed and released when chemical compounds react. The most common application of chemical energy storage is in batteries, as a large amount of energy can be stored in a relatively small volume [13]. Batteries are referred to as electrochemical systems since the reaction in the battery is caused by
