Abstract

Yb2(PtSi)3 crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one Yb2(PtSi)3 ribbon oriented in the (0, 0, 1) direction. Yb3+ is bonded in a linear geometry to one Pt+0.67- and one Si+1.33- atom. The Yb–Pt bond length is 2.65 Å. The Yb–Si bond length is 2.84 Å. There are two inequivalent Pt+0.67- sites. In the first Pt+0.67- site, Pt+0.67- is bonded in a distorted linear geometry to one Yb3+ and one Si+1.33- atom. The Pt–Si bond length is 2.31 Å. In the second Pt+0.67- site, Pt+0.67- is bonded in a distorted linear geometry to two equivalent Si+1.33- atoms. Both Pt–Si bond lengths are 2.37 Å. There are two inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a distorted linear geometry to one Yb3+ and one Pt+0.67- atom. In the second Si+1.33- site, Si+1.33- is bonded in a linear geometry to two equivalent Pt+0.67- 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.
