Investigation of The Effects of Environmental Temperature Depending on Time on Geothermal Resource Parameters in Türkiye

Abstract

Geothermal energy is a domestic energy source that is renewable, clean, and environmentally friendly. Türkiye is in a rich position among the world countries regarding geothermal energy due to its geological and geographical location. The vast majority of these resources are located in the western Anatolia region of the country. Today, geothermal energy obtained in the country is used in areas such as electricity generation, heating, thermal and health tourism, industrial mineral extraction, drying, etc. In this study, the potential of a geothermal energy source in Denizli was evaluated using the volumetric method. The effects of time-dependent both ambient temperature and resource were investigated on an hourly, monthly, and annual basis between 2001 and 2026. The analysis focused on the variation of resource temperature with ambient temperature and the efficiency of the Carnot cycle. The geothermal resource temperature was assumed to be 160°C, with a resource lifespan of 25 years. The lowest source temperature is 100.8°C, and the highest and lowest Carnot efficiencies are obtained as 40.4% and 16.5%. The geothermal resource potential has been calculated to be 74.97 MWe, and the thermal energy stored in the reservoir was determined to be 5.94×10¹5J.

Türkiye'de Jeotermal Kaynak Parametreleri Üzerine Zamana Bağlı Çevre Sıcaklığının Etkilerinin Araştırılması

Öz

Jeotermal enerji, yenilenebilir, temiz ve çevre dostu yerli bir enerji kaynağıdır. Türkiye, jeolojik ve coğrafi konumu nedeniyle jeotermal enerji açısından dünya ülkeleri arasında zengin bir konumdadır. Bu kaynakların büyük çoğunluğu ülkenin batı Anadolu bölgesinde bulunmaktadır. Günümüzde ülkede elde edilen jeotermal enerji; elektrik üretimi, ısınma, termal ve sağlık turizmi, endüstriyel mineral çıkarımı, kurutma vb. alanlarda kullanılmaktadır. Bu çalışmada, Denizli'deki bir jeotermal enerji kaynağının potansiyeli hacimsel yöntem kullanılarak değerlendirilmiştir. Zamana bağlı hem çevre sıcaklığının hem de kaynak sıcaklığının etkileri 2001-2026 yılları arasında saatlik, aylık ve yıllık bazda incelenmiştir. Analiz, kaynak sıcaklığının ortam sıcaklığına göre değişimine ve Carnot çevriminin verimliliğine odaklanmıştır. Jeotermal kaynak sıcaklığının 160°C olduğu ve kaynak ömrünün 25 yıl olduğu varsayılmıştır. En düşük kaynak sıcaklığı 100.8°C olup en yüksek ve en düşük Carnot verimleri sırasıyla %40.4 ve %16.5 olarak elde edilmiştir. Jeotermal kaynak potansiyeli 74.97 MWe olarak hesaplanmış olup rezervuarda depolanan termal enerji 5.94×10¹5J olarak belirlenmiştir.
