Gross Calorific Value vs. Net Calorific Value

On the other hand, NCV only considers the heat released when a fuel is burned, excluding the latent heat of vaporization. This means that NCV provides a more accurate measure of the available energy for practical use, as it excludes the energy required to vaporize water. Therefore, NCV is typically lower than GCV for the same fuel.

CDP Technical Note: Conversion of fuel data to MWh

Net Calorific Values (NCV) = 11.9 TJ/Gg Expression to calculate Energy: Energy = Mass * NCV Step 2 – Analyzing the units of the parameters in the equation Coal is expressed in metric tons and we want to obtain Energy in MWh. The NCV is given in TJ/Gg, so we need to transform it to MWh/t. For that the following reasoning can be applied:
