Keywords Thermal use of the shallow subsurface, shallow geothermal energy, exploration and monitoring strategies.
Abstract The thermal use of the shallow subsurface has
constantly increased over the last years. Frequently
applied techniques that are nowadays used to heat or
cool entire residential neighborhoods or industrial
facilities include borehole heat exchangers and aquifer
thermal energy storage. Despite the capabilities to
reduce CO2-emissions several concerns arise from the
intensive thermal use of the subsurface. Potential
effects include depletion of groundwater quality with
resulting reduction of groundwater ecosystem services
and over-exploitation of the thermal potential with
resulting reduction of system efficiency. Heat and
mass transport by groundwater dispersion and
convection may lead to a carryover of effects into
groundwater dependent ecosystems. Conflicts between
thermal energy use and groundwater protection as well
as conflicts between thermal energy users are expected
to arise. Therefore, an emerging demand exists to
assess potential effects and to develop strategies
towards a sustainable thermal use of the shallow
subsurface.
