NCV takes into account the energy required to vaporize any water produced during combustion, while GCV assumes that all water produced is in a liquid state and no energy is required to vaporize it. As a result, NCV is lower than GCV, and they are expressed in different units of measurement.

In other words, the NCV is derived from the GCV by deducting the latent heat of vaporization of water present and formed. Thus, NCV (MJ/kg.) = GCV (MJ/kg.) − 0.222 (% H) . . . (4.1)

Calorific Value
The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass.
