The aviation industry, known for fostering global economic development, is now confronted with pressing sustainability issues like high carbon emissions and resource depletion. To combat these challenges, the industry is turning towards alternative fuels. Hydrogen fuel has emerged as a frontrunner due to its net-zero carbon emissions, with Airbus leading the charge by aiming to develop a hydrogen engine commercial plane by 2035. Despite the high initial costs, the sustainability benefits of hydrogen make it an attractive option for the industry's longevity. Additionally, advancements in technology, such as digitalization and automation, are enhancing efficiency and reducing human effort in aviation. The industry is also exploring options like Sustainable Aviation Fuels (SAF) and electric or hybrid propulsion systems, with Airbus and Renault Group partnering towards decarbonization. The future of sustainability in aviation looks promising, with a focus on reducing carbon emissions and embracing more eco-friendly technologies to secure a sustainable future for generations to come.
