The aviation industry, currently reliant on jet fuel for all turbine-powered aircraft, is exploring alternative sustainable fuels to reduce greenhouse gas emissions. The transition towards cleaner fuel sources is driven by the need to decarbonize aviation. Hydrogen is emerging as a frontrunner in this transition, with Airbus working on the development of low-carbon commercial hydrogen-powered aircraft by 2035. Despite its potential to only emit water and significantly reduce emissions, hydrogen faces challenges such as high cost, limited infrastructure, and lower energy density compared to traditional jet fuel. Airbus envisions a shift in aircraft design to accommodate larger tanks necessary for carrying hydrogen, aiming to introduce hydrogen-powered aircraft on short-haul routes initially. Additionally, hybrid-electric propulsion systems are being explored to enhance fuel efficiency and reduce consumption, particularly for larger aircraft. The industry is also focusing on the development of the H2 Clipper, a concept airship aimed at serving as a means to transport hydrogen sustainably. Overall, the aviation sector is actively seeking innovative solutions to transition away from kerosene and embrace more sustainable fuel options for a greener future.
