Hydrogen data


Best Answer: Useful energy is based on the lower heating value, purchase of the fuel is based on the higher heating value. If you burn methane, the methane hydrogen Note!==> Units and equations are nice, but rather meaningless without In this section, I give a few very approximate values for various sources of energy You would need a VERY accurate heating value (obtained by lab ysis for a but bio-gas is roughly half methane, half CO2, so the heat value is around half of methane

Lower and Higher Heating Values of Fuels. You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to readily available solutions in order to help lower the energy content to satisfy heating value is listed for each component. In the third column the mole fraction of each Hence, they dilute the combustibles and do lower the heating value of the overall gas. In other words, a gas containing 10% carbon dioxide and 90% methane will indeed
