Munich's Massive Geothermal Survey Deploys 120,000 Sensors and Vibrotrucks
Munich is conducting a large-scale seismic survey to map underground water layers for future geothermal energy. The project uses over 120,000 geophones and vibrotrucks to create a 3D map of the subsurface, aiming to optimize drilling for hot water resources at depths of 1-2 km.
Key points
- Munich is conducting a seismic survey to map underground water layers for geothermal energy.
- The survey uses over 120,000 geophones and vibrotrucks to create a 3D map of the subsurface.
- The goal is to optimize drilling for hot water resources at depths of 1-2 km.
- The survey covers 1,000 km^2 and involves 86,000 seismic excitations.
- The project aims to fill gaps in existing geological data and plan geothermal plant locations.
Background
Munich has existing geothermal plants and prior smaller surveys, but this new project aims to create a comprehensive 3D map of the subsurface to optimize future geothermal energy development. The survey is part of the GIGA-M study, which seeks to improve the efficiency and accuracy of geothermal resource extraction.
Why it matters
The survey provides critical data for planning geothermal energy infrastructure, which could reduce reliance on fossil fuels and provide sustainable heating and power for Munich. The detailed 3D map will help optimize drilling locations and methods, potentially increasing the efficiency and effectiveness of geothermal energy production.
What to watch
The survey is ongoing, and the data collected will be used to plan the placement of geothermal plants and the direction of extended reach drilling. The results will likely influence future geothermal energy projects in Munich and potentially other cities with similar geological conditions.
