Quotes: ""Deep geothermal energy"
"In a demonstration plant in Unterhaching near Munich, sponsored by the German Federal Ministry for the Environment, the forms of utilization heat provision and electricity generation were combined. It was the first plant of its kind in the South German Molasse Basin.""

"An evaluation of the environmental effects of generating electricity with deep geothermal energy has shown that it can make a contribution to sustainable energy supply at present and in the future. The environmental effects are locally limited and technically controllable. Electricity and heat generation from geothermal energy, together with other renewable energies, represents an environmentally and climate-friendly alternative to fossil energy that already avoids greenhouse gas emissions."

"The more advanced scenarios of the 2019 RESCUE study see geothermal as a key source for future greenhouse gas-neutral heat supply. Heat from deep geothermal can contribute to decarbonizing existing district heating networks or expanding district heating as part of energy system transformation, contributing to climate protection at the municipal level."

"The guide, "A New Path to Efficient Heat Networks with Low-Temperature Heat Flows," shows municipalities how deep geothermal or other emission-free heat sources can be used in local and district heating, taking local conditions into account."

"District heating networks and heat storage systems also make it possible to link the power and heat generation sectors and to use the flexibility options of power and heat generation from deep geothermal energy in a way that serves the system."

"Technically, in addition to temperature, the permeability of the rock in the production horizon determines successful geothermal exploitation. In most cases, there is sufficient thermal water and good permeability from the outset, but this could also be increased with the help of hydraulic and chemical stimulation measures."

"Possible environmental effects that are feared in the process - mainly induced seismicity and possible impairments of the aquifers and surface waters serving as drinking water supply - were the subject of an expert report. Here, too, it is shown that there are no uncontrollable risks to the environment if the legal requirements are complied with and suitable early warning systems are used."
