Description
The ground source heat pump (GSHP) system is gaining increasing popularity and use worldwide as one of the most promising renewable energy technologies. In this study, GSHP environmental impacts on the subsurface and the current status of regulations and guidelines were reviewed. Although subsurface temperature changes by utilization of GSHP systems have been observed in several studies, possible negative environmental impacts on the subsurface (labeled “thermal pollution”) have not been well investigated. Current regulations on maximum or minimum temperature thresholds and minimum distances between GSHP systems are only developed empirically and only 6 countries (all in Europe) have legally binding environmental regulations for operating GSHP systems. Our review suggests that for the sustainable usage of GSHP system, comprehensive scientific research on environmental impacts on the subsurface is needed to develop regulations or guidelines also taking into account risk assessment for subsurface thermal pollution.
