WebHow the calorific value (CV) of gas is calculated and how we determine the amount of energy transported by shippers and suppliers, which is used to bill gas consumers. WebThe energy input into a gas engine should be defined using the LHV of the fuel. Fuel suppliers will usually quote the HHV and it will be this measure that will be used when kWh unit charges are applied for the fuel. In the case of natural gas the ratio of HHV to LHV is approximately 1.108:1.
