Over the last years, interest in using ”clean” fuels to support a more sustainable aviation industry has been outstripping. The increasing demand for air travel whilst using conventional kerosene fuels has spiked rapidly the emission levels of CO2 and NOx to magnitudes without precedent. To reduce the aviation environmental impact, hydrogen fuels have been identified as a potential and promising solution. A well popular trend today in aviation is to align the future technologies with the ”Net zero by 2050” project plan established by the European Union during the Paris Agreement, which aims, among many, to neutralize the CO2 emissions. By using hydrogen as an aviation fuel, CO2 emissions are expected to be erased whilst NOx levels to be considerably decreased.
