Revolutionising the Aviation Industry

A Journey to Having Australia’s First Hydrogen-powered Plane in the Sky in 2023

Business Highlights

Aviation H2 is building Australia’s first hydrogen plane, which is expected to be in the sky by 2023. Once complete, they will have a state-of-the-art method for converting aircraft to carbon-free fuel.


  • Feasibility study successfully completed – Results were positive, showing that converting a Falcon 50 to Liquid Ammonia Turbofan Combustion as the most efficient and commercially viable avenue to building a hydrogen-powered plane
  • Company is scheduled to start testing to prove the concept by modifying turbofan engines
  • High calibre team consisting of world-renowned engineers
  • Utilising current technologies and infrastructure for future customers, allowing them to modify the aircraft they have already invested in, rather than buy a whole new fleet
  • Aviation H2 will have a patentable method for modifying aircraft so they operate on carbon-free fuel one tests are proved successful in 2023
  • IPO Q4 2023– Once the test flight is proved successful, Aviation H2 will seek a listing on a major exchange to fund the commercialisation of its technology
  • Early entry into a ground-breaking business set to redefine aviation standards and decarbonise an industry worth over US$330B
  • Access to an Australian-first technology, which uses state-of-the-art applications scalable across international markets
  • Lucrative exit strategies available to the Company; including seeking a listing, licensing the technology to the existing plane fleet, licensing the technology to new fleet builds and potential for acquisition by an OEM aerospace manufacturer


  • Strategic partnership with major operator FalconAir
  • World-class lead engineering partners Make 21st Century Aeronautics and SAAR4324

Company Overview

Since Aviation H2 has appointed Make 21st Century Aeronautics, as their lead engineering partner and elected Helmut Mayer, Christof Mayer, Captain Gregory Keogh and Yianni Chapley to the Board of Directors, much progress has been made.

It’s safe to say the holiday period did not hold us back, which is to be expected. Captain Keogh and Helmut Mayer have shared a passion for flying for over 30 years and held pilot licences.

Now, after a few short months, they are on track to having Australia’s first hydrogen-fuelled plane in the air in the next 18 months.

Even though eager to move quickly on Project Darter Bird, it is important to note they have not jumped the gun and are following a thorough research and testing process. The time is now to start decarbonising aviation, and there is nothing that can’t be done when you employ a relevant dose of thought and attention.



On this point, the company have completed researching the current state of the art and testing the usefulness of potential designs for power creation, energy storage and conversion to thrust. The completed planning study totals over 300 pages and has guided the decisions about which power path, or paths, to pursue detailed design, testing and demonstration. The paths chosen will need to offer opportunities to remove environmental impact, remove hazards, improve efficiency, and further optimise performance in the future.

The evaluation during the planning study included statistical analyses of overall development uncertainties involving both time and the development of technologies. This gives a sound view of project risk as they can collate, while also helping to monitor for over-the-horizon risks as they progress step by step.

Aviation H2 has selected the most promising of the power paths; to store ammonia in modified tanks onboard the aircraft. This would be fed directly into a turbofan engine with modified combustion chambers to burn ammonia instead of Jet-A fuel.

Modifications include:

  • Stabilising the ammonia burn
  • Adjusting fuel-air ratios and the burn itself to reduce NOx emissions
  • Accommodating engine characteristics to suit the difference in density of the fuel-air mixtures
  • Pressurising the fuel tanks so that the ammonia remains fluid throughout the flight.

Using pure hydrogen, co-firing and electric paths are other routes to carbon-free flight we are considering, each with its own unique set of uncertainties and opportunities.

One of the most important elements will be ensuring the approach involves the state-of-the-art conversion of an existing aircraft into a hydrogen-fuelled engine with the majority of the base certification retained.

One of the most critical features of the work is to ensure the existing, and certified, technology as much as possible. 

Once initial testing is completed around November, recommendations will be made to the board and to potential investors. After this, the project’s second phase will begin – building Australia’s first hydrogen-powered plane – which will take us through to the experimental flight of an aircraft.
