The IDTechEx report 'Sustainable Future Aviation 2025-2045: Trends, Technologies, Forecasts' foresees a significant rise in battery-electric powered planes by 2045, pointing out the challenges they face and potential solutions. Energy density remains a primary issue, with batteries being much heavier than traditional fuels, leading to reduced range and increased weight for electric planes. This in turn impacts ownership costs and carbon footprint. Despite these challenges, the report suggests that advancements in battery technology and airframe modifications could improve the situation. Small electric planes find practical uses in flight schools, tourist flights, and island hopping due to their operational cost benefits. However, for long-distance travel, hydrogen and Sustainable Aviation Fuel (SAF) are essential for decarbonization, as electric planes may not be suitable for crossing continents or oceans. The report emphasizes the importance of renewable energy sources and emerging battery chemistries in enhancing the viability of electric aviation.
