Abstract

A scheme has been developed for the use of low-potential energy for heating water, including for the purpose of desalination of sea water. An assessment of the effectiveness of the Kalina cycle is given. It is proposed to use heated water in the water treatment cycle. This cycle can be implemented on geothermal sources near the ocean. Installations based on renewable energy sources fit into the country’s economy in an environmentally friendly way, and also increase energy security. Thus, the cycle is integrated into the seawater desalination system. However, there are some disadvantages to using geothermal energy. First, it is only available in certain parts of the world, since geologically active areas are required to access heat. In addition, installing the necessary equipment and infrastructure can be costly, making it difficult for some people to access this form of energy. Finally, the heat removal process can also lead to environmental degradation as it can harm sensitive ecosystems and water sources in the area.
