Advanced Thermal Technologies for High-Efficiency Conversion and Application of Renewable Energy

Dear Colleagues,

The achievement of global carbon neutrality goals imposes higher demands on the utilization efficiency and supply stability of renewable energy sources such as solar, wind, and biomass. However, the inherent intermittency and low energy density of these resources have become core bottlenecks constraining their large-scale development. Advanced thermal technologies, with their critical supporting roles in energy storage, efficient conversion, and system peak-shaving, are regarded as a vital pathway to address these challenges. This Special Issue will establish an interdisciplinary platform bridging microscopic heat transfer mechanisms and macroscopic energy systems, showcasing cutting-edge explorations in this field. We invite original research contributions on high-temperature thermal energy storage, advanced thermodynamic cycles including supercritical carbon dioxide (s-CO₂) and organic Rankine cycles, photovoltaic–thermal (PV-T) integration, and heat transfer enhancement technologies. Particular interest lies in papers addressing multi-scale simulation analysis, the development of high-efficiency heat exchange components, and system integration optimization for industrial heat and power generation scenarios. This Special Issue will present synergistic advances in theoretical understanding and technological innovation, offering new insights into resolving practical challenges such as relatively low thermal conversion efficiency and high energy storage costs, thereby facilitating engineering validation and large-scale deployment of renewable thermal utilization technologies.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Thermo is an international peer-reviewed open access quarterly 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 1200 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.
