H2FLY

As 2024 comes to a close, we're proud to reflect on an extraordinary year filled with breakthroughs for H2FLY and the hydrogen aviation industry. From pioneering flights to collaborative projects, here are our standout moments: Hydrogen-Electric Flight: Joby Aviation completed a 523-mile hydrogen-electric VTOL flight, demonstrating the potential for emission-free regional travel. We're proud to have designed and built the fuel cell system that powered this groundbreaking flight. GOLIAT Project: We joined Airbus and industry leaders in launching the GOLIAT - Horizon Europe project under the EU’s Horizon Europe Programme, supported by €10.8M in funding to advance LH2 refueling technologies over four years. BALIS 2.0 Funding: We secured funding from the German Federal Ministry for Digital and Transport for the BALIS 2.0 Project, aiming to develop a 350 kW fuel cell system for regional commercial aircraft. Award wins: We picked up two awards, the hy-fcell award in the category of “Research & Development” celebrating the innovative work behind last year’s successful LH2 flight with the HY4, and being featured in Airport Technology & Airport Industry Review's roundup of future aviators. To our team, partners, and everyone who has supported us along the way, thank you. Here’s to an even brighter 2025.

Merry Christmas and a Happy New Year from all of us at H2FLY! 🎄 As we reflect on 2024, we’re filled with gratitude for an incredible year.

The team in Stuttgart enjoyed a fantastic evening at our Christmas party, marking the end of an incredible year. The night was filled with great food, laughter, and a chance to reflect on our achievements. A big thank you to everyone who joined and for all your hard work this year. Wishing our amazing team and their families a joyful and peaceful holiday season.

Thank you to everyone who joined us at the Monaco Hydrogen Alliance Forum. Prof. Dr.-Ing. Josef Kallo shared insights on why liquid hydrogen is the future of aviation and discussed the key challenges in hydrogen power and storage systems. If you missed the conversation, here are some of our key takeaways 👇 Liquid hydrogen is the future: Pairing it with fuel cells and electric motors provides reliable, powerful aviation. Challenges remain: Integrating liquid hydrogen storage, fuel cells, and inverters takes time, engineering innovation, and financial support. Refueling is key: Mastering procedures and hardware architecture is essential for efficient operations. Hydrogen offers greater efficiency: SAF requires 2.1x more energy than hydrogen fuel cells, if whole energy delivery, storage and flight consumption is considered. Renewable energy drives the case: The focus should be on energy sources, not just hardware. It was a pleasure to be part of such meaningful conversations and connect with incredible people, all working to drive hydrogen innovation not just for our skies, but for our seas and roads too.

On December 7th, we celebrate International Civil Aviation Day, dedicated to recognizing the role of civil aviation in connecting the world and supporting economic and social growth. As we look to the future, the commitment to sustainable aviation becomes essential. Advancements in green energy and hydrogen-powered aircraft pave the way for cleaner, more environmentally friendly air travel solutions for future generations. These innovations do more than reduce emissions, they’re catalysts for a sustainable future. #InternationalCivilAviationDay

We're excited to share that Prof. Dr.-Ing. Josef Kallo, co-founder & CTO at H2FLY, will be speaking tomorrow at the Monaco Hydrogen Alliance Forum. 🚀 Panel Session: Ready to Fly? Creating the Business Case for Hydrogen in Aviation ⏰ Time: 10:50 AM - 11:30 AM 🏨 Location: Hotel Hermitage - Salon Eiffel Prof. Dr. Kallo will be joined by industry leaders to discuss the evolving business case for hydrogen in aviation, addressing key technical challenges and advancements in hydrogen power and storage systems. If you’re going to be in attendance, let us know, and connect with us at Josef’s talk. Find out more information here: https://lnkd.in/dihbteN7

We’re excited to announce that H2FLY will be attending the Hydrogen Aviation Summit 2024, hosted by ZeroAvia, this December! Prof. Dr.-Ing. Josef Kallo, co-founder & CTO of H2FLY, will be speaking alongside industry experts like Konstantin Matveev, Professor of Mechanical Engineering at Washington State University, and Dr Chloe Jo Palmer, Hydrogen Fuel System Architect at Rolls-Royce, to discuss the future of cryogenic hydrogen solutions. Hydrogen-powered aviation faces challenges with storing liquid hydrogen at very low temperatures, especially during refueling and to prevent evaporation. This session will explore innovative approaches to improving hydrogen storage, including advanced insulation, reducing boil-off, and better integration of hydrogen into aircraft design. The goal is to make hydrogen a more practical and sustainable fuel for aviation. Join us virtually from 3rd – 4th December 2024, using the link below. https://lnkd.in/e8NdDP9M

We're proud to see our Development Engineer, Stefan Notter, featured in Stiftung Werner-von-Siemens-Ring’s latest article. “Being at the forefront of hydrogen-electric innovation allows me to help create a future where air travel supports environmental goals without sacrificing global connectivity.” - Stefan Notter The article discusses the groundbreaking potential of hydrogen-electric technology in air travel, demonstrating how it can reduce CO2 emissions by up to 90%. It also highlights the significant reduction in noise pollution, making it a key player in the move towards sustainable aviation. Stefan’s work at H2FLY is pivotal in turning these technological advancements into real ones. Read more below. 👉 https://lnkd.in/dfEe3GDi

Our co-founder and CTO, Prof. Dr.-Ing. Josef Kallo has shared his thoughts on the latest research surrounding contrails and the aviation industry’s race to net-zero. “Cutting contrail formation would cut the aviation industry’s carbon impact by 40%...with large-scale, collective investment and support for emerging technologies – such as hydrogen fuel cell propulsion – from industry bodies, politicians, and global players, we can stay on track. However, if these key groups do not act, we may miss these targets entirely.” Read his piece published by FlightGlobal to see why he thinks hydrogen technology is the best long-term solution. https://lnkd.in/gmXWsvRg

Meet Felix Frey Technical Project Manager at H2FLY. Learn how Felix's journey into aviation began and discover what fuels his passion for sustainable flight 👇 How did you get into aviation and end up at H2FLY? My fascination with aviation led me to study Aerospace Engineering. During my thesis at DLR, where I worked on the conceptual design of electric aircraft, I connected with the H2FLY founders and discovered my passion for fuel cell propulsion. While pursuing my PhD in rotorcraft aerodynamics, I kept in touch with the H2FLY team and occasionally provided input on aircraft concepts. When I finished my PhD, H2FLY was spun off from the DLR and I was fortunate enough to join the company. What about H2FLY excites you? I’m thrilled to be part of the electrification of aviation, pushing the boundaries to enable climate-friendly mass mobility. It’s exciting to work with cutting-edge technology, see hardware come to life in the workshop, and collaborate with talented, motivated colleagues. What does your role entail, and how does this help H2FLY’s mission? I coordinate internal work with external project partners and funding authorities. This role helps H2FLY drive sustainable aviation forward through effective collaboration and securing essential funding. What has been your most exciting moment at H2FLY so far? A standout moment was seeing our first in-house developed fuel cell system H2F-175 take flight in the Joby hydrogen-electric demonstrator aircraft earlier this year. Thank you for sharing your story, Felix!
