Özet

This developed combined plant focuses on the thermodynamic and environmental impact analysis of clean and sustainable electricity, heating, green hydrogen, and distilled water production with geothermal energy. This work includes a double flashing geothermal cycle, a reheat CO2 Rankine cycle (re-tRC), a desalination unit (MED), and PEM electrolysis. Using energetic and exergetic efficiency methodologies, the system’s performance changes are examined parametrically. The results are impressive: our system produces a net of 1,857 kW of electricity, and 28.33 kgs–1 distilled water. As a result, the system can produce 0.004595 kgs–1 of green hydrogen at 18.40% energy efficiency and 17.71% exergy efficiency.
