Electric aviation is advancing with several companies targeting short-haul electric flights by 2028-2030. The challenge: batteries are too heavy for long flights. Current battery energy density: ~250 Wh/kg. Aviation needs: ~800 Wh/kg for viable range.
Progress
- Eviation Alice (9-passenger electric plane) in testing
- Heart Aerospace targeting 30-seat regional electric aircraft
- Airbus developing hybrid-electric for short haul
- Urban air mobility (eVTOL) closer to commercialization
Analysis
Electric aviation will happen first in short-haul regional routes (under 500 miles) where current battery technology suffices. For longer routes, hybrid-electric is the transition technology. The economic case for regional electric aviation is strong: fuel costs are 60-80% lower than jet fuel, maintenance is simpler, and noise is dramatically reduced. If battery energy density doubles (achievable by 2030-2035), electric aviation becomes viable for flights up to 1,000 miles.
