Pairing Integrated Gasification and Enhanced Geothermal Systems (EGS) in Semiarid Environments
Energy & Fuels, 2012We explore the feasibility of combining the circulation of supercritical CO2 in EGS reservoirs with integrated gasification combined cycle (IGCC) power generation. The symbiotic benefits of this pairing increase net power output over the use of either system in isolation, reduces water use per MWe, and substantially reduces fugitive emissions over ...

Effect of different flow schemes on heat recovery from Enhanced Geothermal Systems (EGS)
Energy, 2019Operational optimization is the key to maximize the heat extraction efficiency of Enhanced Geothermal Systems (EGS). Injection/production flowrate is one of the operational parameters that can be easily manipulated to produce desired amount of energy. In

Experimental Evaluation of Flow Heterogeneity in Enhanced Geothermal Systems (EGS)
57th U.S. Rock Mechanics/Geomechanics Symposium, 2023ABSTRACT Enhanced Geothermal Systems (EGS) are unconventional reservoirs with significant stored thermal energy and low hydraulic connectivity e.g., Hot Dry Rocks. To take advantage of these resources as a sustainable option, it is necessary to create and/or enhance existing fractures to achieve economic production ...

Deep Learning Based Production Prediction for an Enhanced Geothermal System (EGS)
SPE Canadian Energy Technology Conference and Exhibition, 2023Abstract Hot dry rock (HDR) is a low-carbon geothermal resource and can be an alternative to fossil fuels. The prediction of sequential production is essential for operating a sustainable geothermal system, but its prediction using the numerical simulation method is time-consuming. Deep learning provides an alternative way for this task.

A global review of enhanced geothermal system (EGS)
Renewable and Sustainable Energy Reviews, 2018Abstract The goal of this study is to review 18 significant enhanced geothermal system (EGS) sites and technologies that have been applied in the European Union, Japan, South Korea, Australia and the USA. The results of earlier cases indicate that the site characteristics, such as a transtensional type setting, are a key factor of successful EGS ...
