Current advances in materials science are providing a huge variety of novel adsorbents that could be used for the transformation and storage of low-temperature heat, such as the heat generated by renewable energy sources. Adsorption heat transformation is an energy-saving technology that is used for air conditioning, for either cooling or heating, however, it requires further development in order to be widely employed. Thermal energy storage is a vital technology that helps utilize the energy from renewable sources and enhances energy system efficiency. The creation of adsorbents is crucial for the advancement of adsorptive heat transformation technologies.

The current state-of-the-art technologies in the field of adsorptive heat transformation are limited due to the poor qualities of adsorbent materials. Adsorption heat transformation requires the adoption of innovative adsorbents with superior characteristics in order to advance this field. In commercially available adsorption heat transformation devices, silica gel and zeolites are employed as adsorbent materials and in recent years, metal-organic frameworks (MOFs) have gained increasing interest. As prospective adsorption heat transformation materials, composite materials comprised of salts with silica gels, zeolites, and MOFs, as well as activated carbons, could be widely explored.

The aim of this Special Issue is to discuss the application of novel adsorbents for heat transformation and storage. This Special Issue focuses on the fundamental aspects of adsorption, synthesis, and characterization of advanced materials for the enhancement of the efficiency of adsorption heat transformation devices.
