Australia: “AMSL Aero Collaborates with Conflux Technology for Long-Range Hydrogen-Fuelled Aviation”
Australia-based, AMSL Aero, a developer of zero-emission aircraft, is collaborating with Formula 1 car engine cooling provider, Conflux Technology, to pioneer long-range, zero-emissions flights of up to 1,000 kilometres at Formula 1 car speeds, reports a press release. The announcement was made at the Melbourne Avalon Airshow.
AMSL Aero will use Conflux Technology’s advanced heat transfer innovation to cool the hydrogen fuel cells which power its eVTOL aircraft called Vertiia, enabling a cruise speed of 300 km/h.
Vertiia is an Australian leader in the Advanced Air Mobility sector. The aircraft made its first untethered flights in late 2024.

Chris Smallhorn, Chairman of AMSL Aero, commented, “In Vertiia, we are building a hydrogen-electric aircraft that flies record-breaking distances at Formula 1 speeds, making Conflux Technology, with its past history of innovation in motorsport and aviation, the perfect partner for us.”
He continued, “We are committed to Victoria for future development of Vertiia and Conflux is one of the State’s industrial champions, making the Avalon Air Show the ideal place for us to unveil this partnership.”
The release explains, “The first phase of the project has been completed, which focused on developing three innovative heat exchanger concepts aimed to minimise weight and volume, while effectively managing the continuous heat loads experienced during flight. Following the success of this phase, the project moves into the second phase, where the team will optimise and manufacture a full proof-of-concept assembly to integrate into Vertiia’s hydrogen fuel cell system.”
Michael Fuller, CEO & Founder of Conflux Technology, remarked, “Hydrogen fuel cells are shaping the future of sustainable aviation and thermal management is critical to their performance. By integrating our advanced heat exchange technology with Vertiia’s fuel cells, we’re optimising efficiency and driving the next generation of clean aviation solutions.”
Conflux’s cooling solution will be optimised to provide cooling for high transient heat loads experienced during Vertiia’s VTOL operations.

“Weight, performance and packaging size are key constraints for aeronautical hydrogen powertrains and geometrical freedoms granted by additive manufacturing means heat exchangers for these systems can be lightweight and conform to the space available,” continues the release. “Conflux Technology’s unique thin-walled, patented designs, deliver thermal performance and low drag.”
Vertiia will make its initial hydrogen-electric power flights later this year. This will mark a major step towards AMSL Aero’s goal to manufacture the world’s first long-range passenger-capable hydrogen VTOL.
