Solar thermal storage is a sustainable solution for storing and providing thermal energy, and combining it with heat pumps can significantly improve the overall energy efficiency of the system. In this section, we will
Switching on to solar heat. Sunshine is the most clean, green, & reliable energy source. The only problem is: It''s most available when least needed.. and least available when most needed. Our innovative inter-seasonal thermal storage
Here, a localized solar-heating yarn is achieved by twisting photothermal CNT fibers and water-transported cotton yarns for architecting high-efficiency fabric evaporator, showing a pronounced periodical photothermal difference of 5 °C between CNT and cotton regions in dry state.
Conclusions In summary, a localized solar-heating yarn integrated through twisting of photothermal units and water transport channels is proposed for constructing fabric evaporators, where both CNT fibers and cotton yarns modified by carbon black slurry serve as the solar-heating units and water-supply units, respectively.
Here, an integral solar-heating yarn twisted by both carbon nanotube (CNT) fibers and cotton yarns processed via carbon black slurry is developed for architecting high-efficiency fabric evaporators, where modified CNT and cotton serve as the solar-heating unit and water-supply unit, respectively.
The combined action of light absorber and paraffin enabled the composite yarn to have bidirectional temperature regulation function. This study provided a simple method to construct a multifunctional light-to-heat and phase change yarn, which showed great potentials in thermal storage applications.
The new photothermal and formstable phase change composite yarns could be widely utilised in various fields related to energy conversion and storage.

Diverse types of solar-thermal conversion materials have been utilized for fibers and textiles, including metals, semiconductor materials, carbon-based materials, Mxenes and polymers [101–106]. The novel fibers and textiles are not only for personal thermal management, but also highly advantageous for solar steam generation.
