Should the calorific values be changed from net to gross

2016-9-24 · For gases, these values are converted to NCV in the balance tables. In the IEA Annual Questionnaire both NCV and GCV are reported for coal, while renewables are reported in terms of NCV only. Additionally, classification of coals is done on a GCV basis. Calculations of emissions are based on calorific values.

2018-3-23 · The heat content of natural gas can also vary with impurities. However, if your meter measures cubic meters, your gas bill must show meter readings at start and end of billing cycle, and a calculation to convert that to the billing unit of MMBTU. A typical range for natural gas is 38-39 MJ/m³, and 1 MMBTU = 1.055 GJ, so about 27.4 m³ = 1 MMBTU.
