Stakeholder survey about requirements on shallow geothermal energy
One objective of the GeoPLASMA-CE project is the standardization of methods and parameters for assessment, planning and mapping of the potential for shallow geothermal energy. To achieve this objective, our products have to be harmonized, but also have to display special needs or conditions of certain countries and regions. The survey was performed in the 6 countries involved in the project and addressed the most important stakeholder groups (Figure 1). A set of 65 parameters concerning different aspects of the use of geothermal energy was registered. The results were analysed with methods of the descriptive statistics and the principal component analysis.
- The stakeholders from all countries are interested in (Figure 2):
- supporting information on the suitability of different forms of geothermal energy,
- geothermal potential maps,
- risk and land-use conflict maps,
- information on geology,
- information on existing usage,
- location queries on local scale in PDF format,
- detailed information on groundwater.
However, the countries have specific requirements concerning the physical parameters describing the geothermal potential (temperature, specific heat conductivity, specific heat extraction rate) and the risk factors that are specific on regional level. Some registered parameters were not interesting for most of the stakeholders, like information on certificates of drilling companies or specific risk factors like karst.
The result of the survey indicates that a completely standardized workflow is not useful for the GeoPLASMA-CE partners. Therefore, we recommend a workflow consisting of flexible parts, of recommendations and of requirements.
The completed GeoPLASMA-CE Catalogue of requirements is already available.
