The collaboration will adapt SHZ’s patented LH₂ technologies, including non-conventional storage systems and a revolutionary compressor-pump, to the Z4 platform. Both companies will work under the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 (AACES) project, which is investigating cryogenic hydrogen fuel as a pathway to decarbonising air transport.

 

JetZero received an AACES grant in November 2024 to advance hydrogen integration for commercial aircraft. Its Z4 design, an all-wing configuration, offers up to 50% better fuel efficiency and reduced emissions when operating on conventional jet fuel. With its engines mounted on top of the airframe, the Z4 also reduces airport-adjacent noise pollution by up to four times compared to today’s aircraft.

 

The wide-body all-wing design provides greater compatibility with LHâ‚‚ fuel tanks without impacting passenger seating, a key limitation for traditional tube-and-wing designs. This makes the Z4 well positioned to support a viable hydrogen-powered variant in the future.

 

With SHZ Advanced Technologies contributing its portfolio of 14 patents in hydrogen storage and distribution, the partnership aims to deliver solutions that will help aviation move closer to its Net Zero 2050 goals.
