When computing efficiencies, European power plants sometimes use the LHV of a fuel, while for US power plants the HHV is standard. Consider a power plant burning bituminous coal with HHV/LHV of 31.1/30 MJ/kg. If the power plant’s efficiency is 35% when computed from the HHV, what is its efficiency when computed from the LHV?
