Airside Requirements 89 8.3 Hydrogen Infrastructure Emergence of Hydrogen as an Aviation Fuel Hydrogen is another promising energy vector for electric aviation, especially for larger aircraft. The advantage of H2 is its high-energy density or the electrical energy potential of hydrogen processed by fuel cells compared to its weight.

90 Preparing Your Airport for Electric Aircraft and Hydrogen Technologies Hydrogen Production Hydrogen can be produced from different energy resources such as solar, wind, and nuclear, using raw materials such as water, natural, gas, and coal. Table 16 shows different hydrogen production processes with their corresponding energy source, feed stock, and cost of production.

Airside Requirements 93 Hydrogen Delivery to Aircraft Because of the preliminary stage of the development of hydrogen-fueled aircraft, understanding of the amount of hydrogen needed to fuel different aircraft sizes, fuel tank capacities, and methods of fueling are not definite. Taking hydrogen fueling methods into consideration, hydrogen aircraft can be fueled three ways: • Container Swapping: Empty containers in aircraft are taken out and replaced by filled containers.
