Volume II: Low Enthalpy Geothermal Energy

Low enthalpy geothermal energy has a great potential to reduce the climate impact of building heating and cooling systems. The use of this renewable energy source involves a number of scientific disciplines including energy engineering heat transfer geology hydrogeology chemistry and economics. Low enthalpy geothermal energy i.e. the underground heat available at temperatures below 90°C has great potential in terms of reducing the climate impact of heating and cooling buildings. It can also be employed for other thermal uses such as industrial processes road de-icing and bathing. The Special Issue Volume II: Low Enthalpy Geothermal Energy includes seven articles that discuss the topic from the following points of view: mapping of shallow geothermal potential recent developments for enhancing the performance of borehole heat exchangers exploitation of asphalt-covered surfaces for heating measurement of the thermal conductivity of rocks and sediments and performance monitoring of closed-loop and open-loop low enthalpy geothermal systems.
