Special Issue Information
Dear Colleagues,
In the transient energy context, the increasing penetration of variable renewable energies, such as wind or solar photovoltaic in the electricity mix, requires flexible energy storage systems to balance supply and demand. Large amounts of electricity could be stored using underground space with low environmental impacts. For this purpose, underground pumped-storage hydropower (UPSH), compressed air energy storage (CAES), hydrogen energy storage (HES), underground thermal energy storage (UTES), or gravity energy storage (GES) systems could be developed in disused or new underground structures. This Special Issue will address research on the machinery design, geomechanical analysis of the underground infrastructure, the thermodynamic performance, the geology and hydrogeology, the public acceptance, the environmental impact, the operation modes, the electrical market, the legal regulation, the round trip energy efficiency and the economic feasibility of underground energy storage plants. We would also like to invite authors to address the global potential for expanding underground energy storage systems around the world and to develop specific case studies.

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. Applied Sciences 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
