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.Web

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.Web
