Sustainable and Renewable Thermal Energy Systems

Dear Colleagues,

Sustainable and renewable thermal energy systems have attracted the attention of energy professionals and researchers as efficient and sustainable solutions for heating, cooling and industrial process heating applications. These technologies are capable of delivering the required thermal energy at different temperature levels and can be adapted from small- to large-scale applications. However, low-efficiency thermal storage and the high cost of such devices are still challenging aspects that need more improvement and consideration. Furthermore, the application of optimization algorithms and artificial intelligence techniques in renewable thermal energy systems create the potential for improving the performance, prediction and system operation.

The current Special Issue seeks novel research on renewable thermal solutions, considered a state-of-the-art alternative for climate protection and reducing CO2 emissions. Contributions to this Special Issue are expected to address the most relevant challenges in renewable thermal systems in terms of performance, operation and cost. 

In this Special Issue, original research articles and reviews are welcome. The main topics of interest for this Special Issue include but are not limited to:

1. Renewable thermal solution for sustainable environment.
2. Thermal energy storage systems.
3. Recent progress in solar thermal technologies.
4. Thermo-economic evaluation of renewable thermal technologies.
5. Thermal energy integration and hybrid Approaches.
6. Exergoeconomic analysis and optimization of thermal power plants.
7. Artificial intelligence in renewable thermal technologies.
8. Renewable energy systems for building heating and cooling.
9. Phase change materials.
10. Bio-inspired sustainable energy systems.
11. Recent progress in biomass thermal technologies.
12. Sustainable operation of geothermal power plants.
13. Thermocline Alternatives.

We look forward to receiving your contributions.

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. Sustainability 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 2400 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.
