What the current evidence supports

Human editorial judgment · 2026-07-21

Track; not yet

Why
Credible, well-resourced OEM + engine-maker pairing (Airbus + MTU) with real component-level hardware progress (600 kW motor at >96% efficiency, an operating >500 kW fuel-cell stack test cell), but the JV itself does not yet legally exist, the commercial target is nine years out, and independent cost analysis shows viability hinges on climate policy support that is not guaranteed.
Next
Re-review at JV formation (2027) and after MTU's full-system Flying Fuel Cell demonstrator completes ground/flight testing; watch EU carbon-pricing/kerosene-tax policy as the swing factor for 2035 commercial viability.
