Abstract:
The relevance of this study stems from the desire to develop efficient and
sustainable methods of energy extraction from low-temperature geothermal
resources, which is of key importance in the context of finding alternative
energy sources and reducing dependence on conventional, often nonrenewable sources. The purpose of this study was to analyze the organic
Rankine cycle (ORC) to improve the efficiency of energy recovery from lowtemperature geothermal sources. The present study employed the analytical
method, the deduction method, the induction method, the functional method,
the classification method, the synthesis method. ORC applications for
geothermal energy were comprehensively analyzed, with a focus on the
investigation of low-temperature resources. The best cycle performance
parameters were determined, considering diverse operating conditions.
Concrete technical recommendations were developed for the selection of
organic working media to improve system efficiency. The summarized
findings highlight the potential of the ORC in enhancing the sustainability and
efficiency of geothermal systems.
