Yoğunlaştırılmış Güneş Enerjisi Teknolojisi ve Yatırım Maliyetlerinin Küresel Değerlendirilmesi

Bugünlerde dünya, güneş enerjisi gibi konvensiyonel olmayan enerji kaynaklarına doğru eğilim göstermektedir. Diğer enerji kaynaklarıyla karşılaştırıldığında güneş enerjisinin en önemli avantajı, herhangi bir çevresel kirlilik oluşturmamasıdır. Bu çalışmada, yoğunlaştırılmış güneş enerjisi teknolojisinin (YGE) dünyadaki mevcut durumu, gelişimi, gelecekteki durumu ve uygulamaları sunulmuştur. Parabolik oluk, fresnel aynaları, güneş kuleleri ve parabolik çanak adı verilen dört ana teknolojiden oluşan yoğunlaştırılmış güneş enerjisi teknolojisi yatırım maliyetleri açısından değerlendirilmiştir. Sonuçta, dünyadaki toplam yenilenebilir kurulu güç kapasitesi içerisinde yoğunlaştırılmış güneş enerjisi kurulu kapasite oranının halen %1'in altında kaldığı; ancak gün geçtikçe bu oranın arttığı gözlenmektedir. Buna ilaveten, YGE'nin diğer yenilenebilir teknolojilere kıyasla nispeten düşük maliyetli ısıl depolama avantajına sahip olduğu görülmektedir.

The Global Evaluation of Concentrating Solar Power Technology and its Investment Costs

Nowadays the world trends toward the non-conventional energy resources such as solar energy. The most advantage of solar energy compared to other forms of clean energy is that there is no environmental pollution. In this study, the current status, developments, future projections and applications of Concentrating Solar Power (CSP) technology in the world were presented. CSP technology, consisting of four main CSP technology families called as parabolic troughs, lineer frensel reflectors, solar towers and parabolic dishes was evaluated in terms of investment costs. As a result of this study, CSP is still under 1% within the total global installed renewable power capacity. However, a constant increase is observed in this percentage ratio day by day. Also, CSP has the advantage of relatively low cost thermal storage, compared to other renewable technologies.
