“…Approximately 90% of the world's current energy technologies involve thermal processes ( Henry et al., 2020 ). Examples include conversion of solar energy to heat ( Sharma et al., 2017 ), conversion of waste heat to electricity ( Hung, 2001 ), thermal storage ( Woods et al., 2021 ), cooling and heating of buildings ( Booten et al., 2021 ), and thermal management of various energy devices such as batteries ( Xia et al., 2017 ), microelectronics, and electrical transformers ( Meshkatodd, 2008 ). For example, there is significant interest in using solar thermal processes to decarbonize industrial heating; it is expected that industrial processes requiring medium temperature (<∼150°C) heat can be economically decarbonized using solar thermal processes.…”

Thermal fluids are used as heat transfer fluids and thermal energy storage media in many energy technologies ranging from solar thermal heating to battery thermal management. The heat capacity of state-of-the-art thermal fluids remains $50% of that of water (which suffers from a limited operation range between 0 C and 100 C), and their viscosities are typically more than one order of magnitude higher than that of water. Our results demonstrate that the heat capacity of the proposed thermochemical fluid is significantly higher than that of state-ofthe-art thermal fluids over a broad temperature range and is also higher than that of water between 60 C and 90 C. The viscosity of our liquid is only 3 times higher than that of water, and the operating temperature range is between À90 C and 135 C. Furthermore, a model was developed allowing for novel design of thermochemical thermal fluids in the future with even higher heat capacity.

“…High thermal conductivity is important to achieve high power density, but traditional approaches increase thermal conductivity at the expense of energy density because they displace PCM volume. 89 Furthermore, TES materials that can dynamically tune their phase change temperature or other properties to operate optimally in heating and cooling seasons are needed to increase the utilization factor of TES, lowering the levelized cost. 85 As demonstrated by Woods et al 89 defining material property targets should be driven by component-and systemlevel performance requirements.…”

Because of the complexity of modern buildings—with many interconnected materials, components, and systems—fully electrifying buildings will require targeted R&D and efficient coordination across those material, component, and system levels. Because buildings that consume the smallest amount of energy are easier to electrify, energy efficiency is a crucial step toward fully electrified buildings. Materials advances will play an important role in both reducing the energy intensity of buildings and electrifying their remaining energy use. Materials are currently being explored, discovered, synthesized, evaluated, optimized, and implemented across many building components, including solid-state lighting; dynamic windows and opaque envelopes; cold climate heat pumps; thermal energy storage; heating, ventilating, and air conditioning (HVAC); refrigeration; non-vapor compression HVAC; and more. In this article, we review the current state-of-the-art of materials for various buildings end uses and discuss R&D challenges and opportunities for both efficiency and electrification.

Enhanced Phase‐Change Heat Transfer by Surface Wettability Control

et al. 2022

The phase-change heat-transfer coefficient can be improved by several orders of magnitude through the design of micronanostructures on typical surfaces. However, with the rapid development of intelligent and integrated devices, there is an increasing desire to regulate the heat exchange form of the surface to adapt to various environmental requirements. This study concerns the design of a carbon nanotube array-based phase-change heat-transfer surface, which can switch its wettability between superhydrophobicity and superhydrophilicity. By installing this surface on a device that integrates boiling heat transfer and condensation heat transfer, the device can independently adjust the surface wettability for different heattransfer requirements. As a result, this surface can enhance condensation heat-transfer coefficient over 90 % in the superhydrophobic state and enhance the boiling heat-transfer coefficient over 41 % in the superhydrophilic state. Surfaces with controllable wettability can aid development of a new generation of smart control technologies to actively regulate system and device temperatures.
