Shallow-Geothermal sourced Low-Temperature District Heating

Solutions developed

The S-GeoHeat project focuses on developing integrated solutions for utilizing low-grade geothermal energy sources in district heating systems. These solutions include innovative approaches for building retrofitting, smart control features, and blockchain-based performance monitoring. The aim is to optimize energy efficiency, reduce environmental impact, and promote sustainable heating solutions.

Main results

The main results of the S-GeoHeat project involve developing an integrated approach for utilizing shallow geothermal sources in low-temperature District Heating (DH) systems. Equipped with smart controls and blockchain technology, the aim is to meet end-user demands for space heating and domestic hot water considering two unique case studies (i.e., Havza and Ladik, located in Samsun, Türkiye). Key aspects include assessing building renovation and efficiency measures to maintain system operation at low-temperature levels together with designing DH systems that consider end-user performance and source quality, integrating digitalized asset monitoring and smart control features. Additionally, efforts are directed towards characterizing the geothermal systems to enable sustainable resource use. A pilot demonstration in the Havza District showcases the feasibility of utilizing low-grade shallow geothermal sources for heating, providing insights for broader implementation.
