Gaskets in geothermal energy
In recent decades, geothermal water has become an increasingly important energy source for power generation and district heating, largely driven by the need to combat climate change. This growth trend is expected to persist, prompting the development of additional geothermal plants worldwide to take advantage of this CO₂-neutral resource. However, this transition also presents distinct operational challenges, particularly concerning the valves used in geothermal systems.
Geothermal energy technology works by harnessing the Earth’s heat, stored in geothermal water within the crust, and integrating it into district heating networks. Naturally, the geothermal water rises to about 150 meters (492 feet) without assistance. Depending on the location, surface temperatures range between 120 and 130 degrees Celsius (248 to 266 degrees Fahrenheit).
One of the key challenges in utilizing geothermal water is its high salt content, which causes significant corrosion. Additionally, it tends to form deposits inside pipelines, increasing the risk of blockages. Therefore, selecting and maintaining the right valves is crucial to ensuring the long-term reliability and efficiency of geothermal systems.
