چکیده
در این مطالعه، یک سامانه یکپارچه و چندمنظوره جهت تولید انرژی پاک باهدف بهره‌برداری هم‌زمان از انرژی زمین گرمایی و سرمایش گاز طبیعی مایع‌شده (LNG) طراحی و مورد تحلیل قرار گرفته است. ساختار این سامانه شامل یک نیروگاه زمین گرمایی پیکانه تک‌مرحله‌ای، یک آب‌شیرین‌کن دومرحله‌ای برای تأمین آب موردنیاز، یک الکترولایزر از نوع غشای تبادل پروتون (PEM) برای تولید هیدروژن سبز، و یک واحد تولید توان از LNG است. نوآوری اصلی این طرح، جایگزینی شیر انبساطی رایج با یک توربین هیدرولیکی در مسیر LNG و همچنین ادغام فرایند تولید هیدروژن در ساختار کل سامانه است. نتایج تحلیل انرژی و اگزرژی نشان می‌دهند که بازده انرژی سامانه برابر با ۴/۶۷ درصد و بازده اگزرژی آن ۶۷/۳۸ درصد است که در مقایسه با نمونه‌های مشابه، عملکرد بهتری ارائه می‌دهد. تحلیل جزئی اگزرژی نیز مشخص کرده که بیشترین میزان اتلاف مربوط به واحد آب‌شیرین‌کن است. همچنین، عامل‌های مانند فشار انبساط سیال زمین گرمایی و فشار خروجی پمپ LNG نقش مؤثری در بهبود عملکرد سامانه ایفا می‌کنند. یافته‌های این پژوهش بیانگر پتانسیل بالای سامانه پیشنهادی در توسعه فناوری‌های نوین انرژی پاک و بهره‌برداری بهینه از منابع تجدیدپذیر برای تولید هیدروژن سبز هستند.

چکیده English

In this study, an integrated and multifunctional system for clean energy production has been designed and analyzed, aiming to simultaneously harness geothermal energy and the cooling potential of liquefied natural gas (LNG). The system architecture comprises a single-flash geothermal power plant, a two-stage desalination unit for freshwater supply, a proton exchange membrane (PEM) electrolyzer for green hydrogen production, and an LNG-based power generation unit. The primary innovation of this design lies in replacing the conventional expansion valve with a hydraulic turbine in the LNG pathway, as well as integrating the hydrogen production process within the overall system configuration. Energy and exergy analyses indicate that the system achieves an energy efficiency of 67.4% and an exergy efficiency of 38.67%, outperforming comparable configurations in the literature. Detailed exergy analysis further reveals that the highest exergy destruction occurs within the desalination unit. Additionally, parameters such as the expansion pressure of the geothermal fluid and the outlet pressure of the LNG pump play a significant role in enhancing system performance. The findings highlight the considerable potential of the proposed system in advancing clean energy technologies and optimizing the use of renewable resources for green hydrogen production
