The push for sustainability in aviation has led to a surge in interest and development of electric and hydrogen-powered planes. IDTechEx's report 'Sustainable Future Aviation 2025-2045' sheds light on the challenges and opportunities in transitioning to greener aviation solutions. While electric planes face hurdles in battery weight for longer flights, they show promise for shorter routes under 1000 kilometers. Hydrogen planes, on the other hand, leverage the lightweight nature of hydrogen but grapple with storage and emission concerns. Government and private investments in sustainable aviation projects signal a positive shift towards decarbonizing the industry. As advancements continue in battery and hydrogen technologies, the future of sustainable aviation hinges on strategic infrastructure development and regulatory changes to support these innovative propulsion systems.
