Aviation H2 has ordered the final parts required to complete the modification of a test jet turbine to run with a carbon-free fuel, liquid ammonia.

The Swiwin SW170b-2448 turbine will serve as a proof of concept for the conversion model the Company developed in its feasibility studies conducted throughout 2022 and 2023.

Aviation H2 is also working with machinists to build the specific parts it has designed to complete the modification, which will form a critical part of the IP the Company is developing.

Once operational, it will be one of the world's first liquid ammonia jet engines.

"This marks a major milestone for Aviation H2", says Director & Chief Engineer, Helmut Mayer. "It will provide the aviation industry with a strong proof of concept for decarbonisation which will open up a lot of commercial opportunities for us."

Aviation H2 believes its conversion model will play a key role in decarbonising the aviation industry, as it delivers a cost-effective, right now solution for companies wanting to decarbonise their operations without the significant financial burden of replacing their fleets.

Assessing test engine part deliveries

"We believe offering a model for converting planes to a carbon-free fuel, with minimal changes to the overall design of the aircraft, will be critical to tackling the carbon challenge. As carbon regulations become more stringent, some businesses will struggle to keep up with the capital requirements of replacing their whole fleet."

"Our goal is to deliver a commercially viable solution to help businesses overcome these challenges so they transition smoothly into the net-zero future."

Once the engine modification is complete, Aviation H2 will conduct rigorous testing processes to optimise performance.

Following this, the Company will purchase an aircraft, which it will convert to a liquid ammonia turbine for a test flight.

Once the test flight is successful, the Company will have a patentable method for converting traditional aircraft to operate on carbon-free fuel.

Aviation H2 has strategically chosen liquid ammonia as its preferred hydrogen carrier. By converting existing jets to utilise liquid ammonia, the Company aims to overcome the challenges associated with hydrogen storage and transportation.

Liquid ammonia has several advantages over gaseous or cryogenic hydrogen, including a higher volumetric hydrogen content, easier handling and storage, and existing infrastructure for its production and distribution. This strategic choice positions Aviation H2 at the forefront of innovation, as no other industry players are currently exploring this novel solution.
