In the Ba3As2H12(S4O3)2 framework, there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 3-coordinate geometry to two S2- and three O2- atoms. There are one shorter (3.35 Å) and one longer (3.43 Å) Ba–S bond lengths. There are a spread of Ba–O bond distances ranging from 2.88–2.97 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to four S2- and four O2- atoms. There are a spread of Ba–S bond distances ranging from 3.18–3.48 Å. There are a spread of Ba–O bond distances ranging from 2.79–2.93 Å. In the third Ba2+ site, Ba2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Ba–O bond distances ranging from 2.80–2.89 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded in a tetrahedral geometry to four S2- atoms.

The H–O bond length is 1.00 Å. In the eleventh 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 twelfth 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 eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted single-bond geometry to one As5+ atom. In the second S2- site, S2- is bonded in a 1-coordinate geometry to one Ba2+ and one As5+ atom. In the third S2- site, S2- is bonded in a single-bond geometry to one As5+ atom. In the fourth S2- site, S2- is bonded in a distorted single-bond geometry to one Ba2+ and one As5+ atom. In the fifth S2- site, S2- is bonded in a 1-coordinate geometry to two Ba2+ and one As5+ atom. In the sixth S2- site, S2- is bonded in a distorted single-bond geometry to one As5+ atom.

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.
