Airbus is exploring evolutionary designs for hydrogen-powered aircraft, focusing on maintaining existing fuselage structures while accommodating larger fuel storage. The challenge lies in hydrogen's lower energy density by volume compared to traditional jet fuel, necessitating innovative storage solutions. Meanwhile, Boeing leans towards sustainable aviation fuels, raising questions about the future of zero-carbon aviation. Additionally, startups like Zero Avia are making strides with compressed hydrogen fuel cells for regional aircraft, indicating a rapidly evolving landscape in aviation technology.
