Groundwater has been known as the second largest freshwater storage in the world,
following surface water. Over the years, groundwater has already been under overwhelming …

Despite the intensive studies and advances have been made, the penetration of geothermal
heat exchangers (GHEs) and ground coupled heat pump (GCHP) systems has been …

The borehole heat exchanger (BHE) is an efficient and economic tool for extracting
geothermal energy within ground source heat pumps (GSHPs). The layout and cross-section …

To meet the prospect of carbon neutrality, Deep borehole heat exchanger (DBHE) shows
good potentiality in extracting deep geothermal energy for building heating, especially in …

The effective exploitation of deep hydrothermal resource is an emphasis in the global
geothermal industry. A horizontal-well coaxial closed-loop geothermal system (CCGS) is …

Extracting shallow geothermal energy using borehole heat exchangers (BHEs) can help
decarbonising the residential heating sector, particularly where no other low-carbon heating …

The transition to clean and sustainable energy systems in the building sector is vital to
reduce global greenhouse gas emissions. In this regard, shifting the focus from single …

The horizontal ground heat exchanger (HGHE) integrated with the heat pump unit can be
defined as the horizontal GSHP system. Most horizontal GSHP systems are always …

Among different types of ground heat exchangers (GHEs), multi-external chamber coaxial
GHE is recently a promising design due to its geometrical characteristics of concentric tube …

Deep underground mines offer a great potential as low-enthalpy geothermal resource to be
adopted in direct regional heating. In this paper, a parallel horizontal ground heat …
