Wide Center Body Accommodates Cryogenic Hydrogen

This matters because hydrogen is not just a new fuel, it is a packaging problem, and a blended wing body solves more of that problem inside the airframe than a normal tube does. Liquid hydrogen needs bulky insulated tanks, not thin wing tanks like jet fuel. JetZero’s wide center body gives more room to place those tanks without consuming as much cabin space or forcing awkward tail mounted layouts, which is why the same shape can support both near term SAF use and a later hydrogen variant.

• Conventional airliners are built around a narrow pressurized tube, so hydrogen tanks usually get pushed behind the rear cabin or into other constrained spaces. Airbus used that approach in its turbofan and turboprop ZEROe concepts, while describing the blended wing body as offering many more storage and distribution options because of its wide interior.

• The engineering burden is real. Airbus has spent years building dedicated cryogenic tank programs and test centers because aircraft hydrogen tanks must keep fuel extremely cold, stay light, and fit demanding safety rules. JetZero’s 2025 partnership with SHZ shows it is tackling that tank and plumbing layer early, rather than treating hydrogen as a simple engine swap.

• This wider body also helps on cargo economics. A blended wing body can carry bulky tanks and still preserve a broad internal volume for payload, which matters more in freighters where operators care about usable space and fuel burn per ton moved than about fitting seats into a narrow tube.

The next step is a split market. Tube and wing aircraft will keep improving around SAF and efficiency, while blended wing designs become the cleaner sheet option for airlines, cargo operators, and governments that want true hydrogen readiness. If hydrogen infrastructure matures, JetZero’s airframe architecture gives it a clearer path to adapt than a conventional narrow body or wide body design.
