Aviation is the backbone of our modern society. In 2019, around 4.5 billion passengers travelled through the air. However, at the same time, aviation was also responsible for around 5% of anthropogenic causes of global warming. The impact of the COVID-19 pandemic on the aviation sector in the short term is clearly very high, but the
However, widespread adoption of battery technologies for both grid storage and electric vehicles continue to face challenges in their cost, cycle life, safety, energy density, power density, and environmental impact, which are all linked to critical materials challenges. 1, 2. Accordingly, this article provides an overview of the materials
By 2050, aviation could operate with zero emissions using future aircraft powered by carbon-free energy sources, such as green synthetic fuel, liquid hydrogen and ultra-high power density batteries. Paul Stein predicted that eVTOLs powered by electric generators and batteries would begin to be used for personal and public transport,
As a result, an efficient storage tank system is needed to achieve hydrogen sustainability in aviation. It is noteworthy that unlike jet fuel, hydrogen cylinders can be too large in diameter to fit into aircraft wings. Moreover, with jet fuel stored in the wing tanks, the aircraft''s center of gravity is efficiently managed throughout flight.
Aviation accounts for around 15% of global oil demand growth up to 2030 in the IEA''s New Policies Scenario, a similar amount to the growth from passenger vehicles. Such a rise means that aviation will account for 3.5% of global energy related CO 2 emissions by 2030, up from just over 2.5% today, despite ongoing improvements in

The use of hydrogen as a fuel in civil aviation depends largely on the mass of the tank system. A key parameter for the evaluation of mass development is the gravimetric storage density. With the goal of gaining a maximum equal operating empty weight (OEW), the resulting total mass of hydrogen (fuel) and structural mass must be at
By melting and solidifying at the phase-change temperature (PCT), a PCM is capable of storing and releasing large amounts of energy compared to sensible heat storage. Heat is absorbed or released when the material changes from solid to liquid and vice versa or when the internal structure of the material changes; PCMs are accordingly referred to as latent
