The transformative potential of Enhanced Geothermal Systems on Science in the Virtual & Actual Pub

The transformative potential of Enhanced Geothermal Systems for district heating and cooling Dr. Chloé Arson, Professor, Earth and Atmospheric Sciences, Cornell University An Enhanced Geothermal System (EGS) is a technology used to circulate a fluid through a hot rock formation to harvest heat when that rock does not naturally produce a pressurized heat carrier. Such geological formations are ubiquitous in the U.S., by contrast with hydrothermal sources such as geysers, which are more accessible, but rare. In this presentation, we will briefly review the origin of Earth heat and describe the main geothermal energy technologies available to date, before focusing on the so-called geomechanical aspects of EGS – mainly, the mechanics of rock materials and the interaction between porous solids and the fluids that flow through them. We will review the environmental impacts of EGS for heat direct use, and address some related socio-economic and ethical issues. We will conclude with some of the lessons learnt at the Cornell University Borehole Observatory (CUBO) and explain the some of the research questions that engineers are facing in their quest to develop geothermal energy in the North-East of the United States of America.
