The Rittershoffen geothermal power plant is a project in the Alsatian village of Rittershoffen with the aim of generating heating energy from geothermal energy in order to supply a starch factory in Beinheim .
planning phase
To begin with, three partners have come together to realize the project, which is also funded by the French state:
- The starch manufacturer Roquette Frères , operator of the starch factory in Beinheim, 15 km from Rittershoffen,
- the energy company Electricité de Strasbourg (often abbreviated as ES or Groupe ES), which belongs to the Électricité de France and
- as main financier the Caisse des Dépôts
who together founded the joint venture ÉCOGI ( Exploitation de la Chaleur d'Origine Géothermal pour l'Industrie / dt .: Use of geothermal energy for industry ).
The aim is to generate 24 megawatts of thermal energy by pumping very hot water from a depth of around 2500 meters. The heat from the water tapped by a borehole is to be siphoned off by a heat exchanger and the hot usable water is to be conveyed from Rittershoffen to the starch factory in Beinheim through a 15 km long, very well insulated district heating pipe.
The entire project was calculated at 45 million euros, of which 17 million euros were for the district heating pipeline from Rittershoffen to Beinheim.
The subsurface investigation began in 2011. The first well was officially inaugurated on October 29, 2012. The completion of the geothermal power plant is planned for 2015. [obsolete]
Process for the production of geothermal energy
In Rittershoffen the process is used to develop hydrothermal geothermal energy . In the area of a geological fracture zone , hot thermal water with a temperature of 150 ° C to 170 ° C is to be developed through a borehole at a depth of approx. 2,500 to 3,000 meters . The pipe tour of the borehole pumps the hot water to the surface for further use. A second borehole (double borehole) is drilled into the rock layer to reinject cool water.
Public funding and risk protection
The project is supported by ADÈME ( L'Agence de l'Environnement et de la Maîtrise de l'Énergie ) with 25 million euros. The agency ADÈME will also cover the geological risk of 4.2 million euros; the Alsace region covers the geological risk with two million euros and SAF Environment, a branch of the Caisse des Dépôts, is providing 4.7 million euros for this.
