Where the Big Jets Land, Yielder NFuel, Green Play Ammonia.

Lean and Clean, Ammonia Fueled Falcon 50 form Austrailia. Ready, Set, Go.  

Where the big jets land. Spokane for sure.  It was pretty smokey at takeoff in the 80’s.

Welcome to the Yielder Plant at Fairchild AFB down the road about 15 miles.  

Ammonia makes a breakthrough….Coors Tek is involved all around the world Green NH3 on the way.

Elna can tell you all about it, Her husband John was the Wing Commander….The KC-135 and the BUFF,  B-52H with cruise missiles under their wings, Nuclear tipped…We were shipping Yielder drills….and every afternoon about 500 feet to 750 feet above us was the incoming approach to Fairchild…..Right over the top of us….We Saluted every chance we got…… right over the top of the Yielder Plant in 1983 to 1986 at 4:00 PM every afternoon …in they came, 3 BUFF or B-52 H and three Gas Tanks In the Sky,  KC-135…. like clockwork….and if they didn’t come in on time……something was up.

What Nukes?….Oh those Nukes.  Ready Set Go.

Aviation H2 selects liquid ammonia as carbon-free fuel of choice

28 April 2022

Following a three-month feasibility study, Aviation H2—an Australian-owned company seeking to achieve net-zero emissions in the aerospace sector through green hydrogen—has selected the use of liquid ammonia to turbofan combustion as the best route to carbon-free flight and will soon start modifying turbofan engines to test and prove the concept.

The company, which is launching a $500,000 capital raise via the online platform VCEX to fund the construction of its first modification prototype, says the results from their studies were very positive. Their research shows that converting a Falcon 50 to Liquid Ammonia Turbofan Combustion is the most efficient and commercially viable avenue to building a hydrogen-powered plane.

The company’s team of engineers say they now have a clear pathway to having Australia’s first hydrogen-fuelled aircraft in the skies by the middle of 2023.

By implementing this power path, Aviation H2 can fly aircraft with hydrogen fuel using significantly less weight than alternative power paths while generating the same amount of power.

There are multiple reasons why liquid ammonia was selected. Chiefly its advantages include high gravimetric and volumetric hydrogen density that makes it lighter and easier to transport while providing a greater energy conversion rate. In fact, the stored weight of liquid ammonia energy is substantially lighter than gaseous hydrogen and can be kept at a much lower tank pressure.

Dr Mayer says this is supported by anhydrous ammonia reaching liquification point quicker, which makes it a lot simpler to store when compared to liquid or gasified hydrogen. Additionally, worldwide transportation and handling of liquid ammonia has been around for many years, making ammonia as a carbon-free fuel even more appealing.

The company has selected the Dassault Falcon 50 business jet—a long-ranged international business charter jet aircraft—for the flight test.

The jet has 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.

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.
