Despite the high level of pollution associated with it, aviation until recently appeared immune from the fight against CO2 emissions. Whilst extremely limited experiments with kerosine supplemented with natural fats are in progress (KLM), this does not represent a solution, as, globally speaking, there are insufficient raw materials for large-scale use, and CO2 emissions would not be eliminated, but only reduced. Batteries are too heavy to be a viable alternative and hydrogen gas under high pressure poses all too great a risk.
Airplane technology is placing ever greater demands on electricity. The auxiliary power units (APUs) which are now powered using kerosene have a low yield and supply insufficient current. By replacing these APUs with generators powered with H2Fuel, sufficient current would be generated, making it possible to replace even an airplane’s heavy-duty hydraulic systems with electrical systems and resulting in a 32% reduction in airplane weight (Airbus).
This technology would also make it possible to power the airplane’s engines with hydrogen as fuel, or to electrify them, which would at the same time eliminate much of the noise hindrance it generates. As heat is also released through the process of releasing the hydrogen, it, too, can be utilised for heating and air-conditioning.
