Takeaways

• 😀 The drilling project is located near Munich, in southern Germany, with a depth of 1,800 meters reached so far.
• 😀 The team aims to drill to more than double the current depth, targeting a depth greater than 3,600 meters.
• 😀 The drilling team consists of members from various countries, working on geothermal drilling projects ranging from 100 to 8,000 meters deep.
• 😀 Geothermal drilling technology is almost the same as shale gas drilling, with similar equipment and techniques used.
• 😀 The geothermal drilling installation is the first of its kind in the world, according to the company director.
• 😀 The drilling is currently going down to 4,500 meters in search of suitable rock temperatures for geothermal energy extraction.
• 😀 Once the desired depth and rock formation are reached, the team begins drilling multiple holes that act like giant underground radiators.
• 😀 After a certain depth, the drilling becomes angled rather than vertical, with multiple holes drilled simultaneously.
• 😀 The temperature of the rock at the site reaches 160 degrees Celsius, with the drill bit controlled by magnetic signals to ensure accurate drilling.
• 😀 The project aims to drill 20-30 meters per hour while stabilizing and cleaning the borehole, with 2,400 meters drilled over four days.
• 😀 The geothermal drilling project will take three years, involving around 200 workers, with two boreholes being drilled at the site.
• 😀 Engineers working on the project are residing near the drilling site in a farm area, with plans to build a power plant that will be completed in a year.
• 😀 The geothermal project will combine drilling and power generation to supply heat energy to Munich, providing electricity for 10,000 homes and heating for 80,000 households.
• 😀 Geothermal energy from deep rocks is stable and reliable compared to solar and wind energy, making it a complementary source of renewable energy.
• 😀 The geothermal system will adjust its output based on solar and wind availability, ensuring consistent energy supply.
• 😀 Fossil fuel-based energy plants are being phased out in favor of more environmentally friendly and climate-friendly energy sources.
• 😀 Starting in 2026, Munich will receive energy from this geothermal project, which will provide a greener and more climate-friendly energy supply.

Q & A

What is the main goal of the geothermal drilling project near Munich?
