Abstract

Y3Ru4Ga15 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to four Ru and twelve Ga atoms. There are two shorter (3.38 Å) and two longer (3.40 Å) Y–Ru bond lengths. There are a spread of Y–Ga bond distances ranging from 3.02–3.27 Å. In the second Y site, Y is bonded to twelve Ga atoms to form distorted face-sharing YGa12 cuboctahedra. There are a spread of Y–Ga bond distances ranging from 3.04–3.16 Å. In the third Y site, Y is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Y–Ga bond distances ranging from 3.02–3.11 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded in a 8-coordinate geometry to one Y and eight Ga atoms. There are a spread of Ru–Ga bond distances ranging from 2.54–2.74 Å. In the second Ru site, Ru is bonded in a 9-coordinate geometry to one Y and nine Ga atoms. There are a spread of Ru–Ga bond distances ranging from 2.55–2.82 Å. There are ten inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to three Y, three Ru, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.76–2.92 Å. In the second Ga site, Ga is bonded in a 2-coordinate geometry to two Y, two equivalent Ru, and three Ga atoms. There are one shorter (2.58 Å) and two longer (3.01 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 2-coordinate geometry to four Y, two Ru, and one Ga atom. In the fourth Ga site, Ga is bonded in a 2-coordinate geometry to three Y, two Ru, and one Ga atom. The Ga–Ga bond length is 2.60 Å. In the fifth Ga site, Ga is bonded in a 2-coordinate geometry to two Y, two equivalent Ru, and five Ga atoms. There are one shorter (2.70 Å) and two longer (2.77 Å) Ga–Ga bond lengths. In the sixth Ga site, Ga is bonded in a 10-coordinate geometry to one Y, three Ru, and six Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.73–2.91 Å. In the seventh Ga site, Ga is bonded in a 8-coordinate geometry to two equivalent Y, two equivalent Ru, and four Ga atoms. The Ga–Ga bond length is 2.53 Å. In the eighth Ga site, Ga is bonded in a 10-coordinate geometry to one Y, two equivalent Ru, and seven Ga atoms. The Ga–Ga bond length is 2.69 Å. In the ninth Ga site, Ga is bonded in a 9-coordinate geometry to two Y, two equivalent Ru, and five Ga atoms. Both Ga–Ga bond lengths are 2.79 Å. In the tenth Ga site, Ga is bonded in a 2-coordinate geometry to two equivalent Y, two Ru, and three Ga 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.
