Geothermal water is rapidly gaining importance as an energy source for electricity production and district heating — partly due to global warming. More geothermal power plants are being established worldwide to tap into this CO2-neutral source, but this also brings specific challenges, particularly for the valves in geothermal systems.
The principle: geothermal heat, stored in geothermal water within the Earth’s crust, is tapped and channeled to district heating systems. The water naturally rises to approximately 150 meters and reaches the surface at a temperature between 120 and 130 degrees Celsius, depending on the location.
Due to its high salt content, this water is highly corrosive and causes scale formation, with a risk of blockages. A well-considered choice and maintenance of valves are therefore essential for a reliable and efficient system.
