Abstract

K4Os2CH4O3Cl10CO crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four formaldehyde molecules and one K4Os2CH4O3Cl10 framework. In the K4Os2CH4O3Cl10 framework, there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to two O2- and five Cl1- atoms. There are one shorter (2.64 Å) and one longer (2.82 Å) K–O bond lengths. There are a spread of K–Cl bond distances ranging from 3.08–3.37 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.17–3.79 Å. In the third K1+ site, K1+ is bonded in a 2-coordinate geometry to two O2- and seven Cl1- atoms. There are one shorter (2.69 Å) and one longer (2.74 Å) K–O bond lengths. There are a spread of K–Cl bond distances ranging from 3.12–3.67 Å. In the fourth K1+ site, K1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.16–3.85 Å. There are two inequivalent Os1+ sites. In the first Os1+ site, Os1+ is bonded in a distorted square pyramidal geometry to five Cl1- atoms. There are a spread of Os–Cl bond distances ranging from 2.36–2.49 Å. In the second Os1+ site, Os1+ is bonded in a distorted square pyramidal geometry to five Cl1- atoms. There are a spread of Os–Cl bond distances ranging from 2.36–2.52 Å. C4+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.17 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one C4+ and one Cl1- atom. The O–Cl bond length is 3.27 Å. There are ten inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three K1+ and one Os1+ atom. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the third Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the fourth Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four K1+ and one Os1+ atom. In the fifth Cl1- site, Cl1- is bonded in a 6-coordinate geometry to four K1+, one Os1+, and one O2- atom. In the sixth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to two K1+ and one Os1+ atom. In the seventh Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three K1+ and one Os1+ atom. In the eighth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the ninth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four K1+ and one Os1+ atom. In the tenth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Os1+ 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.
