Special Issue Information

Dear Colleagues,

Concerns about depleting fossil fuels and global warming effects are pushing our society toward the search for new renewable sources of energy, with the potential to substitute coal, natural gas, and petroleum. Renewable energies such as solar and wind are progressively displacing fossil fuels in the production of energy. However, the intrinsic discontinuous nature of renewable energies necessitates the development of storage technologies to overcome the negative effects of transitory weather conditions, modulate low-to-high energy gaps, and achieve continuous 24 h electricity production. In the case of solar thermal electricity (STE) plants, the development of new efficient thermal energy storage (TES) systems that operate at high temperatures is particularly important to improve their efficiency during electricity production. Additionally, thermal energy storage at low-to-moderate temperatures is in high demand to improve the energy efficiency and carbon footprint of numerous industrial processes, buildings, and infrastructures.

This Special Issue welcomes manuscripts that deal with the utilization of materials for thermal energy storage applications, including approaches based on sensible, latent, and thermochemical heat exchange processes. In this sense, we welcome contributions including, but not limited to, solid media storage (e.g., geomaterials, concrete, ceramics, etc.), fluids (e.g., heat transfer fluids, molten salts, nanofluids, etc.), or chemical reactions (e.g., metallic hydrides, carbonates, ammonia, etc.), either for large-scale (i.e., power generation) or small-scale (i.e., cogeneration, active/passive heat management systems in residential and non-residential buildings) storage.

Research papers should highlight novel contributions in the fields of materials design, characterization, or applications in thermal energy storage, by means of numerical modeling and/or experimental work. Review papers in these fields are also appreciated.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Three-dimensional porous network encapsulation strategy is an effective means to obtain composite phase-change materials (PCMs) with high heat storage capacity and enhanced thermal conductivity. Herein, macroporous reduced graphene oxide (rGO) aerogels with adjustable pore size are prepared by the emulsion template method and hydrothermal reduction process. Further, the shape-stabilized rGO-aerogel-based composite PCMs are constructed after the combination of 3D porous rGO supports and paraffin wax (PW) through vacuum melting infiltration. By regulating the pore structure of the rGO aerogel network, the rGO-based composite PCMs achieve excellent energy storage properties with a phase-change enthalpy of 179.94 J/g for the loading amount of 95.61 wt% and an obvious enhancement in thermal conductivity of 0.412 W/m−1·K−1, which is 54.89% higher than pristine PW and enduring thermal cycling stability. The obtained macroporous rGO-aerogel-based composite PCMs with high thermal storage and heat transfer performance effectively broaden the application of PCMs in the field of thermal energy storage.
