Customer ServiceAlthough molecular hydrogen has very high energy density on a mass basis, partly because of its low molecular weight, as a gas at ambient conditions it has very low energy density by volume. If it is to be used as fuel stored on board a vehicle, pure hydrogen gas must be stored in an energy-dense form to provide sufficient driving range.

Customer ServiceWhy LN2 based storage tanks? Latent heat of H2 is very high. The density of H2 is very low, resulting in a low volumetric latent heat! Actively cooled radiation shields. Due to high liquefaction costs, zero boil-off should be the goal for all liquid hydrogen storage tanks.
Customer ServiceLiquid hydrogen is a promising energy carrier in the global hydrogen value chain with the advantages of high volumetric energy density/purity, low operating pressure, and high flexibility in delivery. Safe and high-efficiency storage and transportation are essential in the large-scale utilization of liquid hydrogen.
Customer ServiceAmong these, liquid hydrogen, due to its high energy density, ambient storage pressure, high hydrogen purity (no contamination risks), and mature technology (stationary liquid hydrogen storage), is suitable for the transport of large-volumes of hydrogen over long distances and has gained increased attention in recent years.
Customer ServiceThe density of liquid hydrogen reaches to around 71 g/L at −253 °C [6] where its energy density becomes equal to 8 MJ/L H 2 [2]. It can, therefore, be said that 4 cylinders of LH 2 are equivalent to 1 gasoline tank.
Customer ServiceLiquefied hydrogen has a much higher density than compressed gaseous hydrogen; 71 kg/m3 for liquid hydrogen versus 18 kg/m 3 at 250 bar and 40 kg/m 3 at 700 bar for gaseous hydrogen.
Customer ServiceSimilar to compression of hydrogen, liquid hydrogen storage is a well-established technology . Liquefied hydrogen offers high rates of hydrogen release similar to compressed hydrogen and low adiabatic expansion energy at cryogenic condition [13, 27, 28].
This increases the weight of the storage vessel and substantially decreases the net hydrogen gravimetric energy density. The vessels offer extremely low gravimetric energy density as about 1 wt% H 2 is only successfully stored [11, 12, 14] in a practical manner. The most common material of construction is steel or aluminum alloy [6, 11].
The low volumetric energy density of hydrogen is certainly a great hurdle in the economic and efficient storage of hydrogen and ultimately in the success of the hydrogen economy. In a developed hydrogen economy, hydrogen is expected to be used both for the stationary as well as for the on-board purposes.
A storage method that gives both a high gravimetric energy density and a high volumetric energy density is, therefore, a requirement. Additionally, moderate operating conditions, low enthalpy change, and fast kinetics of the hydrogen storage and release are the requirements.
Liquid hydrogen is a promising energy carrier in the global hydrogen value chain with the advantages of high volumetric energy density/purity, low operating pressure, and high flexibility in delivery. Safe and high-efficiency storage and transportation are essential in the large-scale utilization of liquid hydrogen.
Storage and transportation of hydrogen are vital for the hydrogen value chain. The storage and transportation of hydrogen in the form of liquid hydrogen (LH 2) have the advantages of large volumetric energy density, low operating pressure, as well as high purity, among the current methods [5, 6, 7].
