WebMathematically the relation between both values can be expressed by the following formula [ 2006 IPCC Guidelines, Vol. II, Section 1.4.1.2, Box 1.1] Equation 16: Conversion of higher to lower heating values in GJ/t (= MJ/kg) where HHV = Higher heating value H = Percent hydrogen M = Percent moisture WebThe difference between the higher and lower heating value is the heat of product water condensation. Because the product water may leave the fuel cell in either form, that is, as liquid or as vapor, both values are correct; however, the type of heating value used to calculate the efficiency must be specified. The lower heating value efficiency is:
