Advanced Geothermal Energy Production and Utilization

Dear Colleagues,

During the last decade, geothermal has expanded beyond conventional hydrothermal systems toward engineered, hybrid, and ultra-high-temperature resources that can deliver firm power and industrial heat at scale. This Special Issue aims to showcase state-of-the-art advances that increase deliverability, reduce levelized cost, improve operational reliability, and expand geothermal utilization across power, heat, and integrated energy systems.

Topics of interest for publication include, but are not limited to, the following:

1) EGS stimulation design and reservoir creation, including monitoring, induced seismicity mitigation, and performance forecasting.
2) Superhot and supercritical geothermal systems, including wellbore integrity, completion concepts, and high-temperature flow assurance.
3) Closed-loop and advanced well architectures (multilateral, coaxial, horizontal), including heat-extraction optimization.
4) Geothermal working-fluid innovations, such as CO₂-plume geothermal, sCO₂ power cycles, and hybrid binary configurations.
5) Coupled thermo-hydro-mechanical-chemical modeling and digital twins, including uncertainty quantification and inverse methods.
6) Geothermal for district heating, industrial process heat, and integrated systems, such as heat pumps and thermal energy storage.
7) Data-driven monitoring, control, and optimization of geothermal wellfields and production systems, including machine learning applications for performance enhancement.
8) Techno-economic assessment (TEA), life-cycle assessment (LCA), and market integration strategies for geothermal projects, including ancillary services and flexible dispatch.

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. Energies 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.
