Stralis Aircraft (YC W23)

Some days are routine. Last Friday wasn’t. We had the honour of hosting a German-Australian dialogue that brought together CEOs from some of Europe’s most significant aerospace and defence companies, as well as German and Australian government leaders. All right here in our hangar at Brisbane Airport.  What unfolded was a conversation focussed on rapid prototyping, dual-purpose innovation, investment, and the future of sovereign hydrogen fuel for aviation. New partnerships were formed, and an increased sense of ambition emerged.  With our hydrogen-electric aircraft and cargo drones as the backdrop, we explored what genuine collaboration between Australia and Germany could look like, and what Stralis’s home state of Queensland has to offer as a sovereign base for defence innovation and advanced technology development. A huge thanks to our facilitator, the Honorary Consul of the Federal Republic of Germany in Southern Queensland Michael Rosemann, to our speakers Peta Ellis, Justin McGowan, Shaun Ferris, Vu Tran, and to all participants, Michael Schoellhorn, Christian Leicher (Rohde & Schwarz), Helmut Rauch, Thomas Gottschild, Martin Karkour, Jens Nielsen, Dr.-Ing. Karsten Kalisch, Michael Netter, Dirk Burgbacher, Claudia Lüttringhaus, MArts, Bob Criner, Steffen Geries, Stuart Johnstone, Steven Holden, Nicola Piljic, Devinka Wanigesekera, Brendon Gallaher, Jake B., Trade and Investment Queensland. For our team, hosting this event felt like a natural fit. As many know, we’re working hard to develop a lightweight hydrogen-electric propulsion system for aviation, with a clear commercial entry path. We’re also focussing on a strong dual-use relevance in high-endurance ISR, logistics, austere operations, and low-signature airborne missions. It’s an ambitious flight plan, but we have the technology, the support, and the team to execute it. What’s more, Australia gives us a sovereign development and flight-test base, and we see future value in both crewed regional aviation and defence-adjacent mission aircraft and UAV applications.

Stralis Aircraft plants its European flag! 🇦🇺 ✈️ 🇪🇺 We're excited to announce EVIA AERO GmbH is stepping up from our first European customer to become our official commercial representative across the region. This is a crucial move from ambition to action, formalising one of the sector's most mature commercial structures. EVIA AERO will be on the ground to roll out zero-emission hydrogen-electric aviation, meeting Europe's growing demand for cheaper, cleaner and quieter flights. The patent-pending Stralis-HE hydrogen-electric propulsion system scales to suit a range of aircraft sizes and types, including drones.

We're thrilled to share that our European launch customer, EVIA AERO GmbH, is expanding its partnership with Stralis Aircraft for hydrogen-electric aircraft. This agreement marks the largest single-customer fleet of hydrogen-electric conversions to date, solidifying EVIA AERO as one of Stralis’ earliest key European customers, with five Bonanza-A36-HE aircraft retrofits. The EVIA AERO–Stralis partnership focuses on practical applications of hydrogen electric propulsion technology, expands the possibilities for island hopping in the Mediterranean and in the North and Baltic Seas, replaces fossil fuels, supports tourism and the regional economies of coastal and island destinations, and enables future routes to key leisure and business destinations such as Usedom and Helgoland in Germany or Sardinia in Italy. Stralis is using two Bonanza-A36 aircraft as hydrogen-electric testbeds, aligned with its technology roadmap. The Bonanza platform, suitable for regional routes, will greatly benefit EVIA AERO and similar airlines worldwide. Their 200-kW hydrogen- electric demonstrator will also mark the first piloted hydrogen-electric flight in the Southern Hemisphere from Brisbane Airport. The EVIA AERO vision is to implement a point-to-point network with multiple daily connections between European economic regions, operated entirely with aircraft powered by locally generated green electricity and hydrogen. Bonanza-A36 aircraft deliveries under this latest agreement are targeted to begin in 2029, aligning with the EVIA AERO rollout of decentralised hydrogen and PV-based airport energy systems. EVIA AERO was Stralis’ first European customer for its fleet of Beechcraft 1900D aircraft, a 19-seat regional hydrogen-electric aircraft. EVIA AERO plans to operate a large fleet of these aircraft across Europe's regional routes, forming the core of its zero-emission network. This partnership signals strong commercial demand for hydrogen-electric aircraft in Europe’s regional markets. “This partnership is particularly exciting because, beyond aircraft operations, EVIA AERO is building the energy and infrastructure ecosystem needed to make hydrogen-electric flight a reality,” said Bob Criner, CEO and Co-Founder of Stralis. “Similar to our program in Australia, their holistic approach aims to support a new regional aviation model where aircraft are powered by locally produced green energy, significantly reducing emissions and long-term operating costs.” “Our fleet will be airborne with certified aircraft for our customers at the earliest possible time. To achieve this, the Bonanza A36 is the ideal product,” said Florian Kruse, founder and CEO of EVIA AERO, adding, “The first routes of our regional airline will be island services and medical flights. For this, the Stralis product is perfectly suitable. Additionally, we can train our future pilots on this aircraft at an early stage.” Press release › https://lnkd.in/g-XrQV6a

✈️ Beechcraft Meets the Future: ABS Supports Stralis Aircraft 🌍 Exciting times for the Stralis Team and the Australian Beechcraft Society! Their members recently took to the skies to support our Brisbane-based team on our mission to decarbonize flight. Stralis is developing a high-performance hydrogen fuel cell and electric motor propulsion system, with our first major milestone being a conversion kit designed specifically for the Beechcraft Bonanza. To help our Stralis engineering team understand the soul of these iconic airframes, ABS members Nicholas Lindsay and Kaine Sherwood provided a hands-on demonstration of Beechcraft capability. 📍 The Route: Departing Archerfield (YBAF), the team flew a scenic one-hour loop: ✅ North past downtown Brisbane and Redcliffe (YRED) ✅ Over Bribie Island and across Moreton Bay to Tangalooma (YTGA) ✅ South past Kooringal (YBCX) and Dunwich (YDUN) ✅ Back to Archerfield via Redland Bay Nick Lindsay flew his A36 Bonanza—the baseline for the Stralis transformation—while Kaine Sherwood piloted a Baron to showcase multi-engine performance. It was a fantastic day reinforcing why the Bonanza and the Baron remain the gold standard for General Aviation! 🌟 Huge thanks to Nick and Kaine for representing the Beechcraft community and supporting this pioneering Brisbane project. We can’t wait to see the first "Stralis Bonanza" take flight! ⚡️ #Beechcraft #StralisAircraft #AviationInnovation #SustainableFlight #ABS #ArcherfieldAirport #Bonanza #Baron #BrisbaneAviation

Today we share a huge milestone in the journey toward zero-emission hydrogen-electric flight. The press release and video below celebrate the successful filling of pioneering aviation tanks with liquid hydrogen, that was produced and stored on-site for the first time at an international airport in preparation for pre-flight testing. Liquid hydrogen provides a lightweight zero-emission energy for aircraft and is a credible alternative for the aviation industry. Stralis Aircraft are integrating Fabrum's tanks alongside our hydrogen-electric propulsion system into aircraft. A big shout out to our partners FABRUM. and AMSL Aero #zeroemission #electricaircraft #hydrogenelectric #hydrogen #liquidhydrogen
