Concerning diesel (and petrol is quite similar), Simon Khoury has given you a good answer. It has a molecular weight of 32.04 and boils at 64.7 C and freezes at -97 C. The energy density for methanol is around 22 MJ/kg. (Boiling point of ethane is -88C / -127F, and thus, ethane is present as liquid below this temperature) The output density is given as kg/m3, lb/ft3, lb/gal(US liq) and sl/ft3. Ethane - Density and Specific Weight vs. Hydrogen's flammability range (between 4% and 75% in air) is very wide compared to other fuels, as shown in Figure 3. Energy density is measured by the amount of energy per mass. Calculation of thermodynamic state variables of methane in saturation state, boiling curve. The energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density.A biofuel is a fuel produced from recently living organisms.Biofuels include bioethanol, an alcohol made by fermentationoften used as a gasoline additive, and biodiesel, which is usually used as a . Under the optimal combustion condition (a 29% hydrogen-to-air volume ratio), the energy required to initiate hydrogen combustion is much lower than that required for other common fuels (e.g., a small spark will ignite it), as shown in Figure 4. By Stephen H. Crolius on October 21, 2016. 1 gallon of propane has 73% of the energy in 1 GGE due to the lower energy density of propane. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount ( e.g. Hydrogen can be stored physically as either a gas or a liquid. Methane (US: / m e n / MEH-thayn, UK: / m i e n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). To drive about 1000 km, a truck needs about 80 kg of liquid hydrogen.
