Geothermal Signalling Map: Potential for Deep Geothermal Energy

A signalling map based on rough assumptions shows the potential for deep geothermal energy extraction. The data, provided by the Dutch Ministry of the Interior and Kingdom Relations, describes geothermal systems requiring 1.5 by 3 kilometer underground areas and surface installations of about half a hectare. File formats include WMS, WFS, PNG, and HTML.

Use Cases

• Identify potential sites for geothermal doublet installations based on described subsurface area requirements.
• Plan spatial allocation for geothermal systems requiring half a hectare of surface land.
• Model heat extraction and reinjection cycles for wells drilled between 1000-4000 meters deep.
• Assess regional geothermal energy potential using the map's signalling methodology.

Strengths

• Describes specific technical parameters: drilling depths of 1000-4000 meters and a required underground area of 1.5 by 3 kilometers.
• Published under the CC-PDM-1.0 license, allowing for public domain use.
• Provides multiple access formats including WMS and WFS for integration into GIS workflows.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes the map is based on 'rough assumptions', indicating potential model uncertainty.
