Deep geothermal energy for district heating: lessons learned from the U.S. and beyond

In this chapter, utilization of deep geothermal energy as an economically viable source of energy for district heating (DH) systems is discussed. An overview of enhanced geothermal system (EGS) technology is presented first, focusing on the technology, economics, and challenges and advantages of using EGS for DH systems. This is followed by several case studies, of both real and modeled systems, to illustrate the current and future state of geothermal district heating (GDH).
