Elysian Aircraft is developing the E9X, a battery-electric regional aircraft designed to carry 88-100 passengers on short-haul routes of up to 750 km (with a path to 1,000 km) and zero in-flight emissions. The programme is built on five proprietary technologies — Wing-Battery Integration, Distributed Electric Propulsion, Reusable Battery Packs, a High-Voltage System, and a Reserve Energy System — and is supported by ground and subscale flight demonstrators. In parallel, Elysian licenses its electrification technology stack to other aerospace manufacturers for hybrid-electric, narrow-body, and defense/special-mission applications.

Product overview1 text field

Elysian Aircraft is developing the E9X, a battery-electric regional aircraft capable of carrying 88-100 passengers over 750+ km with zero in-flight emissions, as its primary civil product. The E9X is supported by a suite of core enabling technologies including Wing-Battery Integration, Distributed Electric Propulsion, Reusable Battery Packs, a High-Voltage System, and a Reserve Energy System — all engineered as an integrated electrification architecture extendable to hybrid-electric and fully electric aircraft in both commercial and military domains. To de-risk these technologies ahead of the E9X programme, Elysian operates a set of ground and flight demonstrators including the Scaled Flight Demonstrator (SFD), Wing Integration Mock-Up, Power Distribution Rig, and Battery Demonstrator. The company positions its technologies as dual-use, supporting applications from hybrid-electric and future turboprops to more-electric narrow-bodies and special-mission aircraft.

euronewsShort-haul electric flights could be a European reality in less than four yearsEuropean start-ups such as Vaeridion, Elysian Aircraft, and Aura Aero are developing electric and hybrid aircraft with the goal of achieving commercial certification by 2030 to serve short-haul routes. These developments aim to reduce reliance on volatile jet fuel prices and lower emissions, potentially covering a quarter of Europe's flight routes under 500km. The European Commission has proposed expanding aviation decarbonisation funding to support these technologies alongside sustainable aviation fuels.Le Monde.frDes avions hybrides ou électriques pourraient effectuer une partie des vols de moins de 500 kilomètres en Europe à partir de 2030Transport & Environment and three European aircraft manufacturers (Væridion, Elysian Aircraft, and Aura Aero) issued a joint statement claiming that hybrid electric aircraft could operate on a quarter of intra-European flights under 500 kilometers by 2030. The four organizations identified about two million suitable routes where aircraft cannot realistically be replaced by trains or cars, including cross-sea and mountain routes such as London-Dublin, Barcelona-Ibiza, and routes connecting mainland France to Corsica.The Cool DownNext-gen ceramic battery promises 621-mile electric flights, but skeptics see a long runwayTaiwanese battery manufacturer ProLogium has signed an agreement with Dutch firm Elysian Aircraft to evaluate whether lithium ceramic batteries could power large-scale commercial electric air travel, with a target of enabling flights up to 621 miles on a single charge. The partnership aims to achieve an energy target of 320 to 420 watt-hours per kilogram, addressing aviation's demands for energy density, safety, and weight efficiency. While the development could unlock cleaner and quieter regional air service, experts note significant challenges remain, including the large gap between battery and jet fuel energy density.DIGITIMES AsiaProLogium and Elysian Aircraft sign MoU to explore solid-state batteries for electric aviationProLogium, a Taiwanese battery maker specializing in next-generation lithium ceramic cells, has signed a memorandum of understanding with Elysian Aircraft, a Dutch aerospace startup developing large battery-electric aircraft, to explore the application of solid-state batteries for electric aviation. The partnership aims to leverage ProLogium's solid-state battery technology for use in Elysian Aircraft's battery-electric aircraft development. This MoU represents a strategic collaboration between a battery specialist and an aerospace innovator to advance electric aviation capabilities.Airport Industry-NewsWill Airports Be Ready For Tomorrow’s Electric Aircraft?A study by researchers from TU Delft, NACO, and Elysian Aircraft assesses how existing airport aprons can accommodate the Elysian E9X, a battery-electric aircraft with a 52-meter wingspan comparable to widebody jets but carrying only 90 regional passengers. The aircraft's Code D classification due to its long wingspan creates airport stand compatibility challenges, with solutions explored including MARS stand reconfigurations and PIPO parking configurations that exploit the aircraft's short fuselage. The study concludes that adapting infrastructure is feasible without major construction, though regulatory approval for novel ground procedures could take years, and presents a strategic choice between making airports adapt or adding folding wingtips to the aircraft.PowerprogressProLogium, Elysian Aircraft sign MoU covering battery tech developmentProLogium and Elysian Aircraft have signed a memorandum of understanding to develop next-generation battery technologies specifically for electric aircraft applications. The partnership will focus on evaluating ProLogium's battery cells for the E9X model, aiming to achieve an energy density between 320 and 420 Wh/kg to support ranges of 750 to 1,000 km. This initiative expands ProLogium's operations beyond its existing electric vehicle battery roadmap into the aerospace sector.Interesting EngineeringCeramic aircraft batteries target 621-mile flights on single chargeTaiwanese battery manufacturer ProLogium and Dutch aerospace firm Elysian Aircraft have signed a Memorandum of Understanding to assess the use of next-generation lithium ceramic batteries in large-scale passenger airplanes. The agreement requires developing battery cells with energy density between 320 and 420 Wh/kg to power aircraft capable of flying 750 to 1,000 kilometers on a single charge. The companies will also evaluate establishing manufacturing facilities and supply chains within Europe to strengthen supply chain resilience and reduce carbon footprint.GlobeNewswireProLogium and Elysian Aircraft BV Sign MoUProLogium, a global next-generation battery technology company, signed a Memorandum of Understanding with Dutch aerospace company Elysian Aircraft BV to explore the application of next-generation batteries in all-electric aircraft. The collaboration will focus on developing battery modules and packs targeting energy densities of 320-420 Wh/kg to support large battery-electric aircraft with ranges of 750-1,000 km for zero-emission aviation. This partnership marks ProLogium's expansion beyond its existing electric vehicle battery roadmap into aviation applications, while also assessing localized battery supply chain opportunities in Europe.GoogleLagging Battery Performance Forces Electric Aircraft RethinkAn Aviation Week article reports that overoptimistic projections for battery performance have caused some electric aircraft ventures to falter or fail, while others have lowered expectations to reach a minimum viable product. Dutch startup Elysian Aircraft is cited as an example, with its revised E9X design featuring a longer folding wing and six electric engines versus eight in the original concept.Aviation Week NetworkLagging Battery Performance Forces Electric Aircraft RethinkLagging battery performance has led to a reassessment of electric aircraft designs, with some ventures revising their expectations downward to develop market-ready products. The article discusses the case of Dutch startup Elysian Aircraft, which has updated its aircraft design with a longer wing and fewer electric engines.
