Italian hydrogen storage explosion

Recent advances in hydrogen process safety

The suppression effect of hydrogen explosion is in the order (from strong to weak) of CF 3 CHF 2, CHF 3, and C 3 HF 7. When C 3 HF 7 is used as the suppressing gas, it promotes hydrogen explosion when the volume fraction is less than 10% at a Ф value of 0.8. Significant suppression effects are observed for the Ф values of 1.3 and 1.6.

Blending hydrogen into natural gas can promote hydrogen development and storage tank farms play an essential role in the storage of hydrogen-blended natural gas (HBNG). However, upon leakage from the tank, HBNG accumulates to create a vapor cloud and may explode, resulting in more severe consequences than natural gas and leading to multiple
