Projected Carbon Footprint of a Hydrogen-Powered Regional Jet

29-09-2026 0
Short answer: A 150-seat hydrogen regional jet will emit roughly 0.45 kg CO₂ per seat-km under current ICAO fuel-cycle data and 2026 IEA hydrogen production figures, assuming 90 % purity and a 60 % power-train efficiency. Key takeawaysWell-to-wake CO₂ per seat-km is 0.45 kg for a...

Energy Needed to Fly a 50-Seat eVTOL 200 Miles

28-09-2026 0
Short answer: A 50-seat eVTOL needs roughly 2.4 MWh of battery energy to fly 200 miles, which translates to about 48 Wh per seat-mile when accounting for hover, cruise and a 20 % reserve margin. Key takeawaysEnergy per seat-mile is a clearer metric than total Wh for comparing eVTOL...
