[20.9.2024] A map of the UK geothermal gradient was recently published on LinkedIN by one of our PUSH-IT partners. The Cornwall area is one of the most suitable sites within the UK, with a temperature gradient of 35°C / km. For the Czech Republic, a map showing the geothermal potential has been published two years ago on the site Map of geothermal potential of Czech Republic
The map of geothermal potential was created by a team of scientists from the Czech Geological Survey, the Geophysical Institute of the CAS and the Chamber of Renewable Energy Sources of the Czech Republic based on an extensive analysis of data from more than 300 boreholes. In addition to the potential of geothermal energy, the map also shows its limitations and conflicts of interest. These include, for example, the existence of highways, railroads, airports, power plants and floodplains, as well as undermined areas, karst or protected areas. This gives municipal representatives the opportunity to assess whether geothermal energy is suitable for their location.
The map shows temperatures at depths of 400 m to 5 km, so its results do not apply to the construction of conventional heat pumps, which use boreholes up to a maximum depth of 150 m. In these cases, a difference of several degrees does not play a role. The temperature difference is only important when planning medium and deep boreholes. The area around Litoměřice, which will be used for geothermal energy extraction and heat storage in the rock environment by the SYNERGYS project, has a temperature of 37 °C at a depth of 1000 m. The area around Most, České Budějovice, Hradec Králové and Ostrava has the temperature of 40 °C in the same depth. Near Cheb and Frenštát pod Radhoštěm, the temperature reaches 50 °C.
Compared to the UK, the Czech Republic is therefore much more suitable for geothermal energy use. We hope that the SYNERGYS project will move its use from theory to practice and thus contribute to the decarbonisation of our energy sector.
