Bu çalışmada jeotermal enerji ve Kalina çevrim tabanlı multi-üretim sisteminin enerji, ekserji, ekonomik ve çevresel performansı analiz edilmiştir. Kalina, sıcak su üretim ünitesi, proton değişim membran elektrolizör, amonyak reaktörü ve ters ozmoz ünitesinden oluşan entegre sistem ele alınmıştır. Bu kapsamda hidrojen, amonyak, tatlı su ve sıcak su üretimleri incelenmiştir. Jeotermal kaynak giriş sıcaklığı, jeotermal kaynak çıkış sıcaklığı, Kalina türbin giriş basıncı, Kalina soğuk su giriş sıcaklığı, jeotermal kaynak debisi ve Kalina türbin izantropik veriminin sistem performansı üstündeki etkisi tespit edilmiştir. Ekonomik analiz olarak paranın zaman değerini ortaya koyan dinamik geri ödeme süresi ve net bugünkü değer incelenmiştir. Çevresel analizde ise net sıfır emisyon hedefleri doğrultusunda tamamen yenilebilir enerjiden üretilen yeşil hidrojen ve yeşil amonyağın geleneksel yöntemlerle üretilmelerine kıyasla kurtardığı karbon dioksit ve buna bağlı olarak kazanılan karbon tutarı incelenmiştir. Parametrik analiz sonuçları multi-üretim sistemlerinin performanslarıyla ilgili çıkarım yapılması noktasında enerji ve ekserji analizinin yanı sıra ekonomik ve çevresel analizlerinin de yapılması gerektiğini göstermiştir.
