Hydrogen as an energy vector
The energy density of various energy storage options is provided elsewhere (Table 3.1 in Ref. [196]). Although the LHV of hydrogen is extremely favourable, the issue lies with its low volumetric energy density of 0.0823 kg/m 3 at ambient conditions (298 K and atmospheric pressure) [ 70 ].
Energy Density of Hydrogen
Its energy density is between 120 and 142 MJ/kg. This means that for every 1 kg of mass of hydrogen, it has an energy value of 120-142 MJ. It is highly flammable, needing only a small amount of energy to ignite and burn. Hydrogen burns cleanly. When it is burned with oxygen, the only by products are heat and water.
