Abstract

BaH15Te3(CN)3 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two BaH15Te3(CN)3 sheets oriented in the (1, 0, 0) direction. Ba2+ is bonded in a 3-coordinate geometry to three N3- and five Te2- atoms. There are a spread of Ba–N bond distances ranging from 2.88–2.95 Å. There are a spread of Ba–Te bond distances ranging from 3.61–3.81 Å. There are three inequivalent C+0.67- sites. In the first C+0.67- site, C+0.67- is bonded in a tetrahedral geometry to one N3- and three H1+ atoms. The C–N bond length is 1.47 Å. All C–H bond lengths are 1.10 Å. In the second C+0.67- site, C+0.67- is bonded in a tetrahedral geometry to one N3- and three H1+ atoms. The C–N bond length is 1.47 Å. There is two shorter (1.10 Å) and one longer (1.11 Å) C–H bond length. In the third C+0.67- site, C+0.67- is bonded in a tetrahedral geometry to one N3- and three H1+ atoms. The C–N bond length is 1.47 Å. All C–H bond lengths are 1.10 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Ba2+, one C+0.67-, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Ba2+, one C+0.67-, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the third N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Ba2+, one C+0.67-, and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. There are fifteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the thirteenth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. In the fifteenth H1+ site, H1+ is bonded in a single-bond geometry to one C+0.67- atom. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 4-coordinate geometry to two equivalent Ba2+ and two Te2- atoms. There are one shorter (2.85 Å) and one longer (3.22 Å) Te–Te bond lengths. In the second Te2- site, Te2- is bonded in a 2-coordinate geometry to two Te2- atoms. The Te–Te bond length is 2.94 Å. In the third Te2- site, Te2- is bonded in a 5-coordinate geometry to three equivalent Ba2+ and two Te2- atoms.

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.
