Numerical Analysis of Enhanced Conductive Deep Borehole Heat Exchangers [PDF]
Sustainability, 2021 Geothermal energy is a reliable and mature energy source, but it represents less than 1% of the total renewable energy mix. While the enhanced geothermal system (EGS) concept faces technical validation challenges and suffers from public acceptance issues, the development of unconventional deep-well designs can help to improve their efficiency and ...
