Mauerstetten. To date, three of these projects: Landau (2007), Unterhaching (2008/9) and Bruchsal (2009), have developed to a stage where they are producing electricity. In the wake of the financial crisis and the difficulty in financing projects, combined with public acceptance problems as a result of seismic events in Landau and Basel, development of geothermal energy has come to a standstill in recent years. Drilling was terminated in Kirchstockach, Dürrnhaar, Sauerlach, Insheim and Grünwald; follow-on contracts did not materialize. 11.1 Highlights 11.1.1 Groß Schönebeck- a Large-scale Research Laboratory The scientific findings of investigations at GFZ‘s in-situ geothermal laboratory at Groß Schönebeck are helping to promote the expansion of deep geothermal energy. Groß Schönebeck is a reference site in the North German Basin and an in-situ laboratory of worldwide excellence, in which exemplary research on large sedimentary aquifer systems can be conducted. The research power plant that is being built there will make it possible to scientifically monitor the entire geothermal electricity generation process- from tapping a reservoir through to producing usable energy. Scientists used an old natural gas exploration well that had been drilled to a depth of 4,240 m in 1990 as the basis for their work. In 2003, the depth of the well was increased to 4,309 m and it was fitted out as a natural research laboratory. In 2007, a second well was drilled, 4,400 m deep into the North German Basin. Its temperature is 150 °C. The two wells form what is known as a doublet: the hot water is pumped out of one of the wells (Figure 11.1), used in the power station, and then re-injected into the ground through the other well. Three projects funded by BMU are running at Groß Schönebeck. We shall describe three current sub-projects here as examples. The main focus is on methods of developing sustainable geothermal systems, i.e., what are known as enhanced geothermal systems (EGS). 95% of the geothermal potential in Germany needs this technology to be commercially feasible. A central question here is what impact the combination of natural fractures in the deep rock and fractures artificially created by stimulation have on the extraction of thermal water. 11.2 German National Policy 11.2.1 Strategy Germany is backing renewable energy. The German government‘s energy strategy, which was adopted in September 2010, gives clear signposts for the road towards the renewable energy age: the objective set is that, in the future, renewable energy sources should constitute the major share of the energy mix. The goal is that in the next ten years, by 2020, renewable energy‘s share in gross final energy consumption should be 18% and renewable electricity‘s share in gross electricity consumption 35%. The federal government envisages that by 2050 Germany‘s energy supply will be for the most part based on renewable energy sources: they want to see renewables‘ share in gross final energy consumption rise to 60% and have even greater ambitions for their share in gross electricity consumption, setting a target of 80%. The German government‘s energy strategy backs up its vision of achieving this with specific measures that are subject to constant review. The dramatic events in Japan and the ongoing re-evaluation of whether to extend the life of Germany's nuclear power stations highlight the need to accelerate this development. 110PDF Image | Geothermal Research and Tech IEA
