Artan enerji talebi, enerji kaynaklarına ve ithalata yatırım yapılmasını zorunlu kılmaktadır. Fosil yakıtlar şu anda küresel enerji üretimine hâkim olduğundan, daha temiz enerji alternatiflerine geçiş çok önemlidir. Nükleer güç santralleri ise baz yük oluşu ve düşük sera gazı salımı özelliği ile dikkatleri üstüne çekmektedir. Özelllikle küçük modüler reaktör (KMR) teknolojileri elektrik dışı uygulamalarda önceliklendirilmiş durumdadır. Bu çalışmada, SMR destekli yeşil hidrojen üretiminin havacılık sektörünün karbonsuzlaşması üzerindeki ekonomik etkisi kapsamlı bir şekilde analiz edilmektedir. İlk aşamada teorik olarak literatür taraması ile SMR'lerin teknolojik ve ekonomik özellikleri, hidrojen üretim teknolojisi ile SMR ilişkisi ve havacılık sektörüne entegrasyon potansiyeli incelenmiştir. Havacılık endüstrisi için SMR'ler kullanılarak hidrojen üretiminin maliyet etkinliği değerlendirilmiştir. Ayrıca temel parametreler ve potansiyel fiyat dalgalanmalarını göz önünde bulundurarak seviyelendirilmiş elektrik maliyeti (LCOE) ve seviyelendirilmiş hidrojen maliyeti (LCOH) hesaplanmıştır. ACP100, NuScale (VOYGR-4), BWRX-300 ve i-SMR tasarımlarına özel olarak duyarlılık analizi yapılmış ve sonucunda, işletme ömrü ve indirgenme oranının LCOH üzerindeki etkisi %1'in altında kaldığı görülmüştür. En etkili parametre, yaklaşık %8-9 etki gösteren hidrojenin alt ısıl değeri (LHV) olarak belirlenmiştir. Özellikle, teknolojiye özgü önemli bir farklılık gözlenmemiştir. Tüm parametreler en düşük seviyelerdeyken bile LCOH’ın 6$/kg'ın altına düşmediği gözlemlense de parametrelerde 10%’luk bir değişiklikle hidrojen maliyetinin potansiyel olarak kilogramda $10/kg’a ulaşabileceği sonucuna varılmıştır. Jet yakıtı ile rekabet gücü için LCOH’ın $4/kg’ın altına düşmesi gerekmektedir. Bunun içinde bütün parametrelerin %10 azaldığında oluşan senaryo için LCOE değerinin 42 $/MWh, referans senaryo için ise 33 $/MWh seviyelerine kadar düşmesi gerektiği sonucu elde edilmiştir. Bunun yanı sıra, nükleer enerji, hidrojen ve havacılık üzerine çalışan diğer araştırmacılara da yol göstermek adına hazırlanan başlıca öneriler ve dikkat edilmesi gereken hususlar sonuç bölümünde sunulmuştur.
