In this study, the chemical and isotopic composition of thermo-mineral springs from the Rosario de la Frontera hydrothermal system was used to construct a conceptual model describing the source regions the thermal fluids...

Abstract Yunkai area is located in the southwest of South China Block and is characterized by widespread granite distribution, dense hot spring occurrences, and well-developed deep faults, indicating significant geotherm...

The Deseado Massif, which is located in the western part of the Santa Cruz Province, Argentina, contains numerous hot spring deposits related to the final stages of the Bahía Laura Complex. The aim of this study is to a...

his study focused on the geochemical and isotopic features of thermal fluids discharged from five zones located in the high altitude Puna plateau (Jujuy Province between S 22°20′–23°20′ and W 66°–67°), i.e. G...

Geothermal energy pile is the new pile technology that combines the ground source heat pump technology and building pile foundation. Due to the pile as the heat transfer carrier of ground source heat pumps, the bearing c...

BackgroundThe thermal diffusivity and vertical seepage velocity of porous media are critical to characterizing the mechanisms underlying subsurface heat transfer. These two parameters are typically determined through inv...

Subsurface temperature uncertainty represents a major risk in geothermal drilling, particularly in volcanic systems where permeability, lithology, and fluid circulation create highly heterogeneous thermal regimes. This s...

Abstract The seismic velocity structure beneath East Africa suggests interconnected corridors of hot mantle are upwelling beneath the continent. However, the geochemical evidence for deep mantle in Ethiopia‐Kenya‐Tan...

Abstract The high-temperature rock drilling is a key process in the exploitation of the hot-dry-rock (HDR) geothermal energy. Understanding the abrasive characteristics of HDR is critical for drilling efficiency and cost...

An in-site observation station for soils around the ground heat exchanger (GHE) in the operating process of ground source heat pump (GSHP) is installed to monitor the operation performance of GSHP as well as heat and moi...

Abstract Renewable energy in Africa has gained increasing attention as a strategic pathway to achieving sustainable development, energy security, and economic transformation. A structured search of peer-reviewed studies ...

Abstract The research provides a comprehensive overview of the Spanish energy landscape in 2023, emphasizing the achievements and challenges in transitioning to a more sustainable electricity system in line with EU polic...

Abstract The current study employs Bayesian-regularization optimizer technique with artificial neural networks (BROT-ANNs) to investigate the significance of local thermal non-equilibrium influences on wax + sand-bas...

El presente trabajo es parte de la investigación realizada, para la tesis doctoral inédita de la Ing. María Belén Birche. Se describe brevemente qué es la geotermia, y los sistemas que existen para aprovechar el rec...

A this article presents a design studio model that integrates architectural pedagogy with urban resilience by focusing on the theme of “healing” within a historical context. Conducted in Sarıkaya, an ancient Roman t...

En los últimos años las alteraciones del sistema climático de la Tierra se han intensi!cado con consecuencias cada vez más graves e irreversibles para los ecosistemas y las personas que viven en ella. La problemátic...

Geothermal solid waste is one of the byproduct materials from the geothermal energy process. The silica extracted from this solid waste can be utilized as a raw material for waterproof coatings. The waterproof or hydroph...

Indonesia’s power sector is still dominated by fossil fuels, which makes it difficult for the country to meet its climate goals. This study develops an integrated modeling framework to evaluate long term decarbonizatio...

Subsurface energy transition aims to mitigate climate change impacts by reducing carbon emissions while addressing energy needs through utilization of sustainable subsurface resources. It involves harnessing underground ...

This study presents the chemical and isotopic compositions of hydrothermal gases from fumaroles discharging around Copahue volcano (Argentina). Gas samples, including those from two fumaroles at the active summit crater,...
