Special Issue Information

The energy transition demands innovative solutions to enable a more efficient and sustainable use of resources. In this context, thermal energy storage (TES) in shallow geothermal systems stands out as a highly promising technology to improve demand management, increase system flexibility, and foster the integration of renewable energy sources.

This Special Issue is dedicated to showcasing the latest advances, applications, and challenges related to thermal energy storage in shallow geothermal systems, highlighting its potential as a key tool for building decarbonization and the development of more resilient energy systems.

We invite the scientific and technical community to contribute with original research articles and review papers addressing, among others, the following topics:

  • Novel methodologies for thermal energy storage in shallow geothermal systems.
  • Modeling, simulation, and experimental validation of TES coupled with geothermal systems.
  • State-of-the-art reviews on shallow geothermal energy and TES.
  • Integration of TES with other renewable energies and technologies.
  • Innovative applications in buildings, district heating and cooling, and energy communities.
  • Sustainability assessments, techno-economic feasibility, and social aspects.
  • Connections with new energy vectors and their role in the energy transition.
  • Hybrid thermal energy applications.
  • Optimization approaches and multicriteria evaluation methods for thermal storage systems.

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. 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.
