Materials Data on Y2N6O25 by Materials Project

Abstract

Y(N2O7)2YN2O11 crystallizes in the orthorhombic C222_1 space group. The structure is zero-dimensional and consists of four Y(N2O7)2 clusters and four YN2O11 clusters. In each Y(N2O7)2 cluster, Y is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Y–O bond distances ranging from 2.35–2.57 Å. There are three inequivalent N sites. In the first N site, N is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.23 Å) and two longer (1.28 Å) N–O bond length. In the second N site, N is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.21 Å) and two longer (1.30 Å) N–O bond length. In the third N site, N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.24–1.28 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a distorted L-shaped geometry to one Y and one N atom. In the second O site, O is bonded in a single-bond geometry to one N atom. In the third O site, O is bonded in a single-bond geometry to one Y atom. In the fourth O site, O is bonded in a distorted single-bond geometry to one Y and one N atom. In the fifth O site, O is bonded in a single-bond geometry to one N atom. In the sixth O site, O is bonded in a distorted single-bond geometry to one Y and one N atom. In the seventh O site, O is bonded in a distorted water-like geometry to one Y and one N atom. In the eighth O site, O is bonded in a single-bond geometry to one N atom. In each YN2O11 cluster, Y is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Y–O bond distances ranging from 2.28–2.54 Å. N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.22–1.29 Å. There are six inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one N atom. In the second O site, O is bonded in a single-bond geometry to one Y atom. In the third O site, O is bonded in a single-bond geometry to one Y atom. In the fourth O site, O is bonded in a single-bond geometry to one Y atom. In the fifth O site, O is bonded in a distorted L-shaped geometry to one Y and one N atom. In the sixth O site, O is bonded in a distorted water-like geometry to one Y and one N 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.
