 · It is also known as Higher Heating Value (HCV). Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 0 formed as a vapor. Natural gas prices are decided on the basis of GCV and NCV.
