CsNa2H4O2Cl3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to two Cl1- atoms. There are one shorter (3.45 Å) and one longer (3.46 Å) Cs–Cl bond lengths. In the second Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to two Cl1- atoms. There are one shorter (3.42 Å) and one longer (3.46 Å) Cs–Cl bond lengths. There are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to two O2- and four Cl1- atoms to form a mixture of corner and face-sharing NaCl4O2 octahedra. The corner-sharing octahedra tilt angles range from 43–70°. There are one shorter (2.40 Å) and one longer (2.45 Å) Na–O bond lengths. There are a spread of Na–Cl bond distances ranging from 2.81–2.98 Å. In the second Na1+ site, Na1+ is bonded to two O2- and four Cl1- atoms to form a mixture of corner and face-sharing NaCl4O2 octahedra. The corner-sharing octahedra tilt angles range from 43–68°. There are one shorter (2.39 Å) and one longer (2.42 Å) Na–O bond lengths. There are a spread of Na–Cl bond distances ranging from 2.81–2.90 Å. In the third Na1+ site, Na1+ is bonded to two O2- and four Cl1- atoms to form a mixture of distorted corner and face-sharing NaCl4O2 octahedra.

In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms. There are six inequivalent Cl1- sites.

Cyclic moisture reactivation of calcium sorbents for long duration thermochemical energy storage

The transition to a flexible and reliable energy infrastructure, using electro-thermal energy generation technologies such as geothermal, concentrated solar power, and nuclear, usually demands simultaneous advancement of thermal energy storage (TES) to support on-demand electricity generation and industrial applications while mitigating the inherent intermittency of renewable energy sources and power outages from direct energy generation. Among TES technologies, thermochemical energy storage (TCES) based on calcium looping emerges as a compelling high-power energy storage candidate due to its high reaction enthalpy, compatibility with elevated operating temperatures, and abundance of low-cost materials. However, the long-term durability of calcium-based sorbents for TCES is hindered by surface sintering and particle aggregation, leading to performance degradation over repeated thermal cycles. This study explores a moisture hydration-based strategy to regenerate a degraded calcium sorbent and mitigate performance degradation for long duration TCES. The addition of moisture transforms calcium oxide into calcium hydroxide and produces intercalation water layers, associated with a regenerated surface area and reduced calcium oxide crystallite size. Both these effects are beneficial in restoring the sorbents' reactivity for carbonization. Additionally, an optimized hydration-assisted reactivation protocol balances the recovered energy storage capacity with heating penalty required for moisture removal from hydrated samples, resulting in an enhanced energy storage capacity up to 176% compared to benchmark sorbents that undergo cycling without reactivation after 60 cycles. In conclusion, these results highlight the potential of hydration-assisted reactivation to enhance the long-term performance of TCES, providing an effective pathway to advancing electro-thermal storage technologies.
