EIA projects a greater than 60% increase in commercial air travel seat miles between 2019 and 2050 with a corresponding 38% increase in energy use and a 12% increase in energy efficiency in seat miles per gallon (EIA 2019). This equates to an increase from 1.3 to 1.7 billion barrels of oil per day.
In 2015, the global aircraft fleet consumed 276 million tonnes of jet fuel—7% of global oil products 1. However, reliance on oil products comes at an environmental cost. Aircraft CO 2 emissions

Sections 2.1 and 2.2 provide a description of the main hydrogen storage methods, highlighting their advantages and disadvantages. Hydrogen storage in carbon nanostructures was not investigated in this review because they are characterised by a very low gravimetric density [19], which makes them unsuitable for aircraft applications. 2.1.
The energy density of a hydrogen storage system (2.3 kWh/kg) is around 20 times higher than that of the battery pack. As a result, the energy storage capacity and the endurance of the aircraft with FC energy storage system can be 15 times extended comparing to its original structure. 3.2. System mathematical model and power
