Enhanced geothermal systems (EGS): A review

Renewable and Sustainable Energy Reviews, 2016
Abstract Geothermal energy is a renewable energy source that can be found in abundance on our planet. Only a small fraction of it is currently converted to electrical power, though in recent years installed geothermal capacity has increased considerably all over the world.

A global review of enhanced geothermal system (EGS)

Renewable and Sustainable Energy Reviews, 2018
Abstract 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 ...

Efficient workflow for simulation of multifractured enhanced geothermal systems (EGS)

Renewable Energy, 2019
Abstract The increasing demand for clean energy with minimum environmental impact motivates development of geothermal energy. Simulating a geothermal reservoir is complex and time consuming, mainly because of the systems spatial and temporal non-isothermal nature and the enormous size of the domain/reservoir. Simulations become even more complex when
