Analysis of the Wider Potential for Heat Pump and Geothermal Energy Integration in Traditional Systems and Grids

The current energy security crisis is primarily a heating crisis. Space and water heating accounts for almost one-third of the EU’s final energy consumption, and unfortunately, around 62% of this demand is still met by fossil fuels. In this context, heat pumps, geothermal energy, and other renewable energy sources emerge as crucial technologies offering effective solutions to enhance energy efficiency and decrease dependence on fossil fuels as well as to achieve the EU energy and climate goals. This article focuses on the analysis of the potential and opportunities of using heat pumps and geothermal energy in conventional heating systems and district heating networks. This topic requires an in-depth analysis of the current state, challenges, benefits, and prospects of these technologies in the EU market. By examining the possibilities for wider adoption and discussing the associated factors, the article aims to provide valuable insights into and recommendations for the advancement of heat pumps and geothermal energy in the EU, along with the presentation of some case studies in this field.
