The company has also selected the Dassault Falcon 50 business jet – a long-ranged international business charter jet aircraft – for the flight test.
This is due to the jet having three engines, of which only two are required for flight, allowing the third engine to be used to test a smaller engine modified to use liquid ammonia before moving on to modify the main engines.
Falcon 50s also have a larger weight capacity, reducing the risk posed by weight challenges. The costs for the test program are no larger than when using a smaller and newer type of jet.
They are also relatively common in Australia, meaning there is a time-saving in getting the aircraft ready for testing.
“Proving liquid ammonia through the modification of existing engines allows future customers to modify their existing aircraft rather than buying new fleets.”
The company believes making use of current technologies and infrastructure will be important to future customers because it allows them to modify the aircraft they have already invested in, rather than buy a whole new fleet.
Once the test flight is successful in the middle of 2023, Aviation H2 will have a patentable method for modifying aircraft so they operate on carbon-free fuel. They will quickly seek to certify and commercialise this product via a planned public listing on a major exchange in Q4 of 2023.
