What the current evidence supports
Human editorial judgment · 2026-06-28
Track; not yet
- Why
- Genuine flight-proven LH2 fuel-cell firsts (4 flights, >3 h piloted; 523-mi Joby flight on the H2FLY system) but still sub-commercial scale with severe volume/cost/infrastructure penalties and no closed certification path
- Next
- Monitor the H2FLY/DLR/Deutsche Aircraft 328H2-FC (1.5 MW, 40-seat CS25) demonstrator first-flight milestone and the H2F-175 (27,000 ft) system; revisit when a >19-seat certified powertrain or an LH2 airport-refueling standard appears
