Commercial aviation is facing challenges in reducing its climate impact and meeting the goal of net-zero emissions by 2050. Companies like Dutch startup Elysian, Etihad, Airbus, ZeroAvia, and Eviation Aircraft are pioneering the way towards greener aviation solutions. Etihad's Greenliner program has shown significant emission reductions, while Airbus aims to launch hydrogen-powered aircraft by 2035. ZeroAvia and Eviation Aircraft have demonstrated the capabilities of hydrogen and electric-powered planes. However, the industry acknowledges that electrification in aviation is more complex than in road vehicles, with the need for battery technology advancements. Other initiatives, such as Harbour Air's all-electric seaplane and Faradair Aerospace's fuel-efficient design, highlight the ongoing efforts to make aviation more sustainable. While challenges remain in sustainable fuel production and technology development, the push for innovative solutions like hydrogen-powered aircraft offers hope for a greener future in aviation.
