Sıvı hidrojen

Sıvı hidrojen tankı

Sıvı hidrojen (LH2 veya LH2), element halinde bulunan hidrojenin (H2) fiziksel olarak sıvı halde bulunan çeşididir. Genellikle havacılık ve uzay ile gaz sanayinde kullanılır.

Hidrojenin, sıvı halde olabilmesi için kritik noktası olan 33 Kelvinin altına soğutulması gerekmektedir. Ancak hidrojen, atmosfer basıncında kaynama olmadan tamamen sıvı halde olabilmesi için ise 20.28 Kelvinin (-423.17 °F / -252.87 °C) altında olması gerekmektedir.[1][2]

Sıvı hidrojenin yoğunluğu sadece 70.99 g / L (20 K'de), rölatif yoğunluğu sadece 0.07'dir. Spesifik enerji diğer yakıtların yaklaşık iki katı olmasına rağmen, çok daha düşük bir hacimsel enerji yoğunluğu vermektedir.
