With the increasing discussion about energy security and energy costs, one source of energy is often completely neglected. Geothermal not only can provide power, but more importantly – in the European context – provide a welcome source of heat. District heating systems fuelled by geothermal are already in place in various countries of this world and could provide a real alternative to other imported sources of energy.
The GeoDH platform published a while ago a great fact sheet on financing geothermal district heating systems. It not only talks about the context in general, but also technologies and how these systems can be financed.
GeoDH SYSTEMS:
• Doublet concept of heat extraction
• Modern doublet designs include two wells drilled in deviation from a single drilling pad.
• Current development are based on the utilisation of shallow geothermal resources, assisted by large heat pumps.
• Two scenarios are possible with DH to be adapted or to be created:
- Cogeneration of electricity and heat with minimum geothermal temperature of 80°C
- Heat production is possible with resources from ca. 150°C to 45°C. Very low temperature geothermal district heating systems can be used only for underfloor heating.
