Low Heating Value - an overview | ScienceDirect Topics

Low heating value gas (3.5 to 10 MJ.m − 3 or 100 to 270 Btu.ff –3) typically consists of syngas mixed with relatively high amounts of N 2 or CO 2, which result in its low heating value. This fuel is typically used for combustion applications where high purity or specific CO/H 2 ratios are not needed.

Hydrogen as a fuel and energy source | Viessmann

Hydrogen is also the lightest gas. Its volume-related energy density is just 3 kWh/Nm3; that of petrol on the other hand is 8800 kWh//Nm3. The standard volume given here as Nm3 is a unit of measurement for gas volumes at identical pressure and temperature levels. When used as a fuel, hydrogen is therefore either highly compressed or condensed.
