How to Calculate Higher Heating Value | Hunker

Higher heating value (HHV) is one measure of the energy content of a material. It is almost exclusively used in measuring energy content for fossil fuels and their alternatives, such as oil, coal, natural gas and biomass. HHV is the upper end of the energy content, and it includes the energy in water evaporated from the fuel as it is combusted.
