Closed-loop geothermal systems, recently referred to as advanced geothermal systems
(AGS), have received renewed interest for geothermal heat and power production. These …

Here, we investigate the techno-economic feasibility of an enhanced geothermal system
(EGS) for direct heating, using a new horizontal-well with partially-bridging fractures design …

This paper presents a new version (v2. 0) of the geothermal techno-economic simulation
tool GEOPHIRES [GEOthermal energy for Production of Heat and electricity (“IR”) …

Flexible energy resources are key for a reliable power supply in a decarbonized grid with a
significant fraction of variable power sources. Whereas the development of fossil fuel …

Techno-economic performance of hybrid ground-source (geothermal) heat pump systems
for cooling-dominated applications has been investigated. An experimental hybrid ground …

Closed-loop geothermal systems (CLGSs) rely on circulation of a heat transfer fluid in a
closed-loop design without penetrating the reservoir to extract subsurface heat and bring it …

The technical and economic performance of hybrid geothermal heat pump (GHP) systems
supplying year-round cooling to small data centers were analyzed and compared to air …

Direct-use of geothermal energy currently has limited penetration in the United States, with
an estimated installed capacity of about 500 MWth, supplying on the order of 0.01% of the …
