Web30 nov. 2024 · It doesn’t matter if you start with natural gas or electricity to make hydrogen, the best you can do is to convert about 70% of the feed energy — lower heating value (LHV) of methane, or kWh of electricity — into the lower heating value of product hydrogen. Best case.
WebLHV = 50.025 MJ/kg The LHV is calculated assuming that water remains in the gas phase. However, more energy can be extracted from the mixture if this water is condensed. This value is the higher heating value (HHV). The ideal gas mixture model used here cannot calculate this contribution directly. kiss heardleWeb1 gallon of propane has 73% of the energy in 1 GGE due to the lower energy density of propane. 2.2 lbs.
