Geothermal-Alliance Bavaria 2nd Project Phase
Subproject efficiency: Development of a more efficient and reliable submersible pump motor
This project is funded by the federal state of Bavaria as part of the cooperative research network „Geothermie-Allianz Bayern“. This interdisciplinary alliance of research institutions aims to pool competences related to geothermal energy systems throughout Bavaria, e.g. mechanical engineering, electrical engineering, chemistry, geology and economics.
Geothermal energy can be used to provide both, electrical power or thermal power, which makes it a versatile resource for renewable energy and a promising supplement to the energy mix of low-carbon power systems. Unlike wind energy or PV, geothermal power generation is plannable and, hence, may be used to provide base load power. However, the electric submersible pump (ESP) which is used to transport geothermal fluid to the surface is exposed to severe stresses due to high temperatures and water pressure. This constitutes the major bottleneck of the technology as the maintenance expenses for geothermal power plants are comparably high. In order to increase the reliability of such systems the main objectives of this project are:
- Development of a more efficient and reliable electric submersible pump motor
- Assembly of a prototype
- Test, analysis and measurement of prototype
- Implementation of a sensorless control strategy
