About This Topic

Geothermal energy production was always linked to the advancements of energy conversion as well as heat harnessing. Conventionally thermal heat output of a geothermal source is 10 times higher than its electrical output, but innovative technological developments may change this. Direct usage of heat from geothermal sources is also highly connected to breakthrough innovations and optimized used of the available resource. With this in mind I challenge the scientific community and invite you all help sharing the latest innovation related to the Advancement of Geothermal Technology for Sustainable Energy Production.


Manuscripts should be submitted online at 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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. Guidelines for authors and other relevant information for submission of manuscripts are available on the Instructions for Authors page. Journal of Energy and Power Technology is an international peer-reviewed Open Access monthly journal published by LIDSEN.

Planned Papers

Title: Environmental Value Considerations in Public Attitudes about Geothermal Technology in the Western U.S.
Author: Brent S. Steel
Affiliation: School of Public Policy, Oregon State University, Corvallis, USA
Abstract: The 2013 Pacific Coast Action Plan on Climate and Energy signed by the Governors of Oregon, California, and Washington and the Premier of British Columbia, launched a broadly announced public commitment to reduce greenhouse gas emissions through multiple strategies. Those strategies include the development and increased use of renewable energy sources. The initiative recognized that citizens are both a central component to abating greenhouse gas emissions with regard to their energy use behaviors, and are important participants in the public policymaking process at both provincial, state and local levels of government. The study reported here examines whether either support or opposition to the development of geothermal energy can be explained by environmental values. The research results are based on surveys of randomly selected households conducted throughout the region in 2013.

Seismic Imaging of Convective Geothermal Flow Systems to Increase Well Productivity

Received: 03 December 2019;  Published: 29 July 2020;  doi: 10.21926/jept.2003012


A core feature of convective geothermal resource production is wellbore energy flow Q ~ ρC x T x V. E.g., for wellbore fluid of volume heat capacity ρC ~ 4.3MJ/m3oC, temperature T ~ 230oC, and volumetric flow V ~ 50L/s, wellbore heat energy production is Q~ 50MW

Experimental Vapor-Pressures and Derived Thermodynamic Properties of Geothermal Fluids from Baden-Baden Geothermal Field (Southeastern Germany)

Received: 24 September 2019;  Published: 24 December 2019;  doi: 10.21926/jept.1904006


Background: In the present study, vapor-pressures of three geothermal fluids from Baden-Baden geothermal field (Kirchenstollen, Friedrichstollen, and Murquelle, southeastern region of Germany) were measured over the temperature range of 274–413 K. The combined expanded uncertainty of the temperature and vapor-pressure measurements at 95 [...]
