Citizens' initiative against geothermal energy (06. Juli 2022)

Quotes: "Brühl. "After the press reports on deep geothermal energy are almost overflowing, the company 'GeoHardt' is also gradually letting the cat out of the bag and concretely names the places it has preferably chosen as possible geothermal sites: Mannheim, Brühl, Ketsch, Schwetzingen, Plankstadt, Heidelberg and Oftersheim as well as around Hockenheim"..."

"The selection of the area does not come as a surprise, given all the support that State Secretary Dr. Andre Baumann has been providing for the past two years, the statement continues. Baumann has repeatedly organized excursions to the geothermal power plants in Bruchsal, Insheim and to the Vulcan Energie laboratory in Karlsruhe, he said. In addition to the originally planned heat generation, a pure lithium hype has been ignited in the meantime by the geothermal companies and Baumann, the BI criticizes in a statement."

"In addition, Vulcan Energie suddenly appears in the Hardt exploration area, although the mining office had already granted the exploration permit to the company "GeoHardt" in September 2020."

""We already pointed out to Dr. Baumann in August 2020 in a two-hour conversation all the risks, dangers and inconsistencies around geothermal energy, such as seismicity, groundwater hazards, radon, as well as the senselessness of the reversal of the burden of proof and traffic light regulations," Rainer Hüngerle and Thomas Gaisbauer of the citizens' initiative reminded us. He had explained on it that nothing happens, if it is made correctly and one should have nevertheless confidence in the policy..."

"On our question, why the country does not take over then a warranty for Geothermal damage, if allegedly nothing can happen, he answered that that would go then to loads of the taxpayers and would be unfair..."

"It is often claimed by geothermal companies that one must drill several wells per plant in order to distribute the pressure on the rock over a large area and then nothing could happen, summarizes the BI. But Insheim's results have shown for ten years that this concept has not worked."

"When it comes to the pressure needed to operate a plant, Vulcan Energie is stingy with concrete information, the BI criticizes, including how much deep water they would need to produce per plant to meet their own expectations and those of their shareholders."

"Vulcan Energie, they say, only announces that they plan to produce lithium hydroxide starting in 2024 and to deliver 40,000 tons per year starting in 2025 based on contracts already signed..."Now follow own calculations of the citizens' initiative:"And so, with 10,000 tons of lithium hydroxide per plant and year, they have calculated that "around 125 deep geothermal power plants would be built here in a very confined space - if the company wants to achieve the same output instead with the five to six power plants that have been envisaged so far, the flow rate would consequently have to be increased, which means it would have to pump between 2084 and 2500 liters of deep water per second, believe it or not, per plant. That is completely out of the question." Bruchsal, for example, produces 24 liters per second, Landau 50 and Insheim 65. "It should be remembered that even the 100 liters per second specified by Dr. Horst Kreuter, head of Vulcan Energie, results in over a third of a million liters per hour that must be forced through rock - in an area that is one of the most earthquake-prone in all of Germany," the BI leader says."...
