• This mechanical energy is converted into electrical energy in generators
• Injecting water back underground after cooling

The pipes and fittings used in this process are very important because they play a critical role for energy efficiency and system safety.

Geothermal power plants provide long-term and sustainable energy with minimal environmental impact.

Working Principle of Geothermal Energy

Geothermal energy generates energy using the heat of hot rocks, magma or hot water layers beneath the earth’s crust. These heat sources have a constant temperature profile, providing reliable energy infrastructure all year round. These systems are based on bringing high-temperature steam to the surface and using it for energy conversion processes.

Deep wells are drilled to reach these hot springs underground and these wells are equipped with high temperature resistant pipe systems. After the hot water or steam is brought to the surface, turbines and generators are activated, which convert the energy of the steam into mechanical movement, and then into electrical energy. After the cooling process, water that has turned into a liquid state is injected underground again, creating a sustainable cycle. The design and operation stages of these systems are of critical importance for stable and efficient energy production.

Transportation to High Temperatures
