Gross CV = Net CV-Lf*(%Hydrogen content)*0.09. If H = 0% then Gross CV = Net CV.

Net calorific value (NCV) supposes that the products of combustion contain the water of combustion to the vapor state.

Gross calorific value (GCV) supposes that the water of combustion is entirely condensed.

Since water in any state is hydrogen compound so its absence can make them same.
