The Advancement of Geothermal Energy Utilisation by New Developments

Dear Colleagues,

Achieving a low carbon and sustainable economy involves energy transition from fossil fuels to renewables. Geothermal energy is a main contender in diversifying the energy supply and the large scale integration of Earth’s heat into the energy mix. At the same time, competing with other renewables, both for heating and cooling and for electricity generation, it is necessary to use brand new technologies to ensure efficient, sustainable, competitive operation with geothermal energy supply. These new technologies include exploration, installation and operating phases which provide an opportunity to determine the optimal operating conditions and mitigate the expected geological risks.

A method to maximise the use of medium and low enthalpy resources, both for electricity generation and direct use, is the cascading use of geothermal energy, including the heat pumps at the end of the system. To address this issue, we welcome all research efforts and projects underway to utilize geothermal heat. Studies on the replacement of fossil energy with geothermal energy in large district heating systems will be considered particularly important.

In addition, we are looking for papers about the further development of technologies known as Enhanced Geothermal Systems (EGS) that can transform otherwise barren or unattractive geological environments into geothermally potential/attractive environments. This includes frontier areas of geothermal energy research such as extra deep "ore-body supported geothermal system" to combine metal and heat extraction.

This special issue is intended to encourage original contributions on the latest developments and ideas related to geothermal energy utilisations. We welcome paper proposals for low-medium-high enthalpy, hydrothermal, petrothermal, shallow and deep systems to present the most competitive geothermal systems to help the penetration of the geothermal sector in developing and developed countries worldwide. Please kindly note that the special issue that at least 5 publications will be published in paperback copy.

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. 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.
