In the realm of automotive and aviation industries, the focus on transitioning to greener energy sources has sharpened. While the automotive sector heavily leans on battery technology for electrification, concerns about the environmental impact of batteries and their reliance on electricity from harmful sources have emerged. However, proponents of hydrogen advocate for its adoption as a cleaner and more sustainable alternative due to its abundance and minimal emissions. The aviation industry, particularly Airbus, is exploring hydrogen as a promising fuel for reducing carbon emissions. Airbus' Cryoprop project, operated by its subsidiary UpNext, is set to showcase the potential of superconducting technologies in electric propulsion for hydrogen-powered aircraft. With the capability to significantly decrease CO2 emissions and boasting high energy efficiency, hydrogen stands out as a key player in the shift towards a greener future in aviation, despite existing technological challenges.
