Pricing
Primarily B2B hardware sales and retrofit/conversion programs; pricing appears custom/contract-based rather than public list pricing.
Differentiators
- —Hydrogen-electric propulsion rather than battery-only range extension
- —Claims of being 6x lighter than current state of the art
- —Claims of up to 10x-30x longer flights than battery-electric alternatives
- —Retrofit path for existing piston-engine aircraft
- —Liquid-hydrogen integration and testing focus
- —Certification-oriented development with ground and flight demonstrators
