Creation of a complex for the production of heat and electric power based on the geothermal waters of the Zharkent depression

The object of this study is renewable energy sources in the Republic of Kazakhstan, with an emphasis on the geothermal resources of the Zharkent field. Geothermal energy is a promising direction in ensuring energy independence and sustainable development, especially in the context of the need to decarbonize the economy and reduce dependence on fossil fuels. The objective of this work is to develop and scientifically substantiate an integrated complex for the production of heat and electricity based on the geothermal resources of the Zharkent field. The study included an analysis of the hydrogeothermal characteristics of the field, an assessment of the energy potential of existing geothermal wells, and a selection of the most efficient technologies, including binary geothermal units, heat pump systems and direct heat supply systems. A feasibility study of the proposed solutions was carried out considering the climatic, geological and infrastructural features of the region. The research results can be applied in the development of pilot projects in the field of geothermal energy, as well as within the framework of the state strategy for the transition to a «green» economy. The proposed complex is capable of increasing the energy sustainability of the Zhetysu region and becoming an example for the implementation of similar solutions in other regions of Kazakhstan.
