55 MJ/kg. Gravimetric energy density, sometimes referred to as specific energy, is the available energy per unit mass of a substance. Gravimetric energy density is typically expressed in Watt-hours per kilogram (Wh/kg), or Megajoules per kilogram (MJ/kg). [1] The gravimetric energy density gives the energy content of a fuel in terms of storage ...
