Three New Zealand and Australian companies developing and deploying liquid-hydrogen technologies to enable Australasia's first hydrogen-electric flights have made a significant step forward in the transition to zero-emission aviation. Fabrum, AMSL Aero and Stralis Aircraft have successfully filled pioneering aviation tanks with liquid hydrogen produced and stored on-site for the first time at an international airport in preparation for pre-flight testing.

Fabrum designed and manufactured the advanced composite liquid-hydrogen tanks for the aircraft companies AMSL Aero and Stralis Aircraft. The refuelling was successfully completed at Fabrum's dedicated liquid-hydrogen test facility at Christchurch airport in New Zealand, developed in partnership with the airport at its renewable energy precinct.

Christopher Boyle, managing director of Christchurch-based Fabrum, a world leader in zero-emission transition technologies, says: “Our lightweight composite tanks, together with our hydrogen liquefier and refuelling systems, are critical enablers for hydrogen-powered flight. By bringing all the elements together for the first time on site at an international airport, producing, storing and dispensing liquid hydrogen into composite aviation tanks as a fuel, we're proving that liquid-hydrogen technologies for aircraft are now available and that hydrogen-electric flight will soon be a reality in Australasia.”

Dr Adriano Di Pietro, CEO of Sydney-based AMSL Aero, the developer of Vertiia, the world-leading hydrogen-electric vertical take-off and landing (eVTOL) aircraft, adds: “Vertiia is the world's first eVTOL designed from inception to be powered by hydrogen for long-range, cargo and passenger operations. Vertiia must be as light as possible to achieve its 1,000 km range, 500kg payload and 300 km/h cruising speed. Liquid hydrogen is the lightest zero-emission method of storing energy for long-distance flight; no other technology currently comes close. We often get asked, 'You are flying Vertiia and are developing an end-to-end hydrogen system, but what else needs to happen to make Vertiia fly on liquid hydrogen?' Today, with Fabrum, we have demonstrated the key steps in that process: from producing liquid hydrogen to filling our ground transport container, then filling the tanks that we will install to our aircraft before our first liquid hydrogen flights next year. This is a major milestone.”

Bob Criner, CEO of Brisbane-based Stralis Aircraft, a developer of high-performance, low-operating-cost hydrogen-electric propulsion systems, states: “It's fantastic to see more of Fabrum's hydrogen technologies unveiled and tested. We are working with Fabrum to develop onboard tanks for our fixed-wing test aircraft to supply hydrogen to our hydrogen-electric propulsion system. We're excited to see Fabrum's hydrogen fuel dispensing systems for these onboard tanks proven out in testing. This is a vital step toward our first liquid hydrogen test flights.”

Christchurch Airport CEO Justin Watson notes: “It's fantastic to welcome aviation industry leaders paving the way for a transition to a low-emissions future here at the airport. Christchurch airport continues to play a leadership role in advancing zero-emission infrastructure, positioning the airport to support liquid-hydrogen aviation.”

Hydrogen advancements stem from strong industry collaboration aimed at accelerating zero-emission aviation. Fabrum, AMSL Aero and Stralis Aircraft are members of the Hydrogen Flight Alliance in Australia, which is advancing the development of hydrogen-electric flight. AMSL Aero was recently awarded a grant from the Australian Government Department of Industry, Cooperative Research Centres Projects (CRC-P) Program for a 'Liquid Hydrogen Powered Aircraft for Regional and Remote Australia' project, with Fabrum among the collaborators. Stralis Aircraft and Fabrum have also received support from Ara Ake, New Zealand's future energy centre, to fast-track hydrogen technology for Australasia's first liquid-hydrogen-powered flight.
