Engineered Geothermal Systems (EGS): Advances in Exploration, Thermal Storage, and Energy Utilization

Dear Colleagues,

Engineered Geothermal Systems (EGS) represent a transformative pathway toward reliable, low-carbon, and dispatchable energy production. As global energy systems transition to sustainable alternatives, EGS has emerged as a promising solution by enabling geothermal energy extraction in regions lacking natural hydrothermal resources. This Special Issue focuses on the latest advancements, challenges, and future prospects of EGS technologies—spanning exploration techniques, subsurface characterization, enhanced reservoir stimulation, and long-term thermal energy storage and utilization.

We invite contributions that address interdisciplinary aspects of EGSs, including Reservoir Geomechanics, reservoir engineering, heat transfer modeling, drilling innovations, and techno-economic evaluations. This Issue also aims to highlight breakthroughs in machine learning, experimental studies, and field-scale demonstration projects that are critical for scaling EGS systems worldwide.

By bringing together leading research across academia, industry, and government, this Special Issue provides a comprehensive platform to foster collaboration and accelerate the deployment of EGS as a cornerstone of clean energy infrastructure. We hope it will serve as a valuable reference for scientists, engineers, policymakers, and stakeholders involved in shaping the future of geothermal energy.

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