Abstract

SrSn2O5Cl6 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two SrSn2O5Cl6 ribbons oriented in the (1, 0, 1) direction. Sr is bonded to five O atoms to form distorted SrO5 trigonal bipyramids that share corners with two equivalent SnCl3O tetrahedra. There are a spread of Sr–O bond distances ranging from 2.32–2.91 Å. Sn is bonded to one O and three Cl atoms to form SnCl3O tetrahedra that share a cornercorner with one SrO5 trigonal bipyramid. The Sn–O bond length is 1.90 Å. There are a spread of Sn–Cl bond distances ranging from 2.35–2.40 Å. There are three inequivalent O sites. In the first O site, O is bonded in a linear geometry to one Sr and one Sn atom. In the second O site, O is bonded in a water-like geometry to one Sr and one O atom. The O–O bond length is 1.24 Å. In the third O site, O is bonded in a single-bond geometry to one Sr atom. There are three inequivalent Cl sites. In the first Cl site, Cl is bonded in a single-bond geometry to one Sn atom. In the second Cl site, Cl is bonded in a single-bond geometry to one Sn atom. In the third Cl site, Cl is bonded in a single-bond geometry to one Sn 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.
