Is liquid hydrogen safer than liquid methane?

  • T. D. Donakowski


This paper compares the physical and combustion-related properties of the liquid state of hydrogen (LH2) and methane (LCH4). This type of comparison is important for studying the safe use of these chemicals as aircraft fuels, although it cannot yield definite conclusions because the actual effect on safety depends on the conditions of the accident.
