Special Issue Information

Dear Colleagues,

As one of the important members of the clean renewable energy family, the development of geothermal resources has been gaining increasing attention; especially when facing the pressure of carbon neutrality and carbon emission reduction, the development of geothermal resources has become an important choice for many countries. Driven by the demand, both geothermal exploration technology and geothermal development have made great progress. High-temperature drilling technology continues to make breakthroughs, ground source heat pump technology has emerged to occupy a large geothermal market, medium- and low-temperature geothermal power generation technology continues to make breakthroughs in power generation increasing year by year, and hot dry rock development exploration is booming everywhere, etc. Therefore, it is necessary to systematically sort out the geothermal exploration and development work in different regions in order to provide reference for geothermal resource development in other regions in the future. To this end, we present a Special Issue of Resources focusing on the exploration and management of geothermal resources, publishing high-quality research in this field.

Areas of research for this Special Issue include (but are not limited to) the following:

  • Regional geothermal resource distribution and potential;
  • Geothermal resource exploration;
  • Direct utilization of geothermal resources;
  • Geothermal power generation;
  • Hot dry rock resource development;
  • Geothermal development environmental response.

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. Resources 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 1600 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.

This paper investigates the total environmental impacts of a thermal caisson (TC) system by implementing a life cycle assessment methodology. The total environmental impacts consider the comprehensive effect on the environment across two life cycle stages: manufacturing and operation. A comparison between the TC results and two different HVAC systems, including air-conditioning/furnace and conventional ground-source heat pump (GSHP) systems, was made by adopting the ReCiPe 2016 methodology. This study reveals that the operation phase is the predominant contributor to environmental impacts across systems, mainly due to its extended duration. Specifically, the operational impacts of GSHPs are substantial, accounting for approximately 87% of total environmental impacts. A TC GSHP system demonstrates a notable environmental advantage, achieving a 79% reduction in total environmental impact when compared to traditional AC/furnace systems. This represents a 21% improvement over conventional GSHP systems. Despite this substantial reduction in total environmental impact, the TC GSHP system shows an almost 5% increase in the resource availability damage category relative to the conventional GSHP, which is attributed to its higher material consumption. These results highlight the TC GSHP system’s superior efficiency in reducing environmental impacts and its potential as a more sustainable alternative in residential heating and cooling applications.
