Geothermal Energy
Geothermal is a clean, renewable, sustainable energy source used for power generation and district heating/cooling. Removing thermal energy from the ground is a challenging process, and geothermal wells must withstand extreme conditions. Vallourec’s tubular solutions allow geothermal assets to resist corrosion, intense pressure and high temperatures.
Engineering tubular solutions for geothermal wells
Geothermal has proven potential as a clean energy source that can be accessed 24/7. Geothermal energy can be used distributed through turbines for power generation, or feed directly into district cooling or heating systems. However, the investment required to drill geothermal wells is high, and operators have traditionally offset these costs by using basic tubulars. This approach can be insufficient, and a potentially risky choice for operators in the long-term. Since geothermal wells are meant to operate for decades at a time, their tubulars must be able to consistently withstand a harsh environment. Choosing the right tubular solutions is critical to ensuring resistance to corrosion, erosion, changing temperature cycles and more, and can help owners optimize the costs of their geothermal assets.

Geothermal energy is a key pillar of the energy transition, offering clean and sustainable power generation...
Geothermal operators are facing several technical challenges that need to be tackled to ensure that geothermal wells are reliable on the long-run and optimized in terms of heat supply efficiency. The premium solutions (material, grades and services) that have been used for decades in Oil & Gas activities show promising results in enhancing geothermal wells’ reliability and performance. However, specific evaluations need to be performed to guarantee their compatibility.
Geothermal power is a clean, renewable, dispatchable and versatile source of energy and is poised to be a key contributor is the decarbonization of our economies.
We believe our expertise in geothermal wells will contribute to the standardization efforts initiated by the IGA, and ultimately help unleash the full potential of geothermal power!
The Earth is constantly radiating heat from radioactive decay.
By harvesting this underground heat, geothermal plants can produce continuous power all year round, making geothermal energy the only baseload and dispatchable renewable energy source.
