At normal atmospheric pressure and ambient temperature, you would need approximately 3,000 litres of gaseous hydrogen to achieve the same amount of energy as one litre of kerosene fuel. Clearly this is not feasible for aviation. One alternative would be to pressurise the hydrogen at 700 bars – an approach used in the automotive sector.
Currently, the energy storage is dominated by banks of batteries, but other forms of energy storage are beginning to appear alongside them. CAES is one of them. The first such system was a 290 MW ...

As defined in section 3.3.51.2* of NFPA 30, Atmospheric Tank is a storage tank that has been designed to operate at a pressure ranging from atmospheric through a gauge pressure of 1.0 psi (6.9 kPa) (i.e., 760 mmHg through 812 mm Hg) measured at the top of the tank. Note that Atmospheric tanks are not Low-Pressure storage tanks.
LPG gas cylinders (propane tanks) may also be called "Propane Gas Bottles", "LPG Bottles", "LPG Gas Bottles" or just "Gas Bottle". LPG gas cylinders (propane tanks) work by containing both liquid and gas, as LPG liquefies under relatively low pressure. An LPG gas cylinder (propane tank) is considered low pressure versus high ...
The energy demand of a hydrogen storage system includes the costs of supplying heat and electricity during both the storage and release of hydrogen. For certain storages, notably those that are "cold" (liquid hydrogen, adsorption), there will also be a cost associated with storage itself, either in the form of operating costs of continuous cooling …
