A Note on Power Plant Selection for Engineered Geothermal Systems

Smith, I. K. ORCID: 0000-0003-1524-9880 (2023). A Note on Power Plant Selection for Engineered Geothermal Systems. Proceedings of the Institution of Mechanical Engineers Part C: Journal of Mechanical Engineering Science, doi: 10.1177/09544062231166804


An initial study has been carried out to determine the most suitable system for recovering power from Engineered Geothermal Systems. When using a binary power plant, account has been taken of the relatively rapid temperature decline of such resources. A simplified idealised analysis shows that the total recoverable power is more or less independent of the type of power plant used but a system that maximises the heat recovery from the brine, in its passage through the primary heat exchanger will yield a much higher initial power output and a much quicker return on the capital invested, than one which is designed to maximise the power plant cycle efficiency.
