At H2FLY, we are proud to have women on board who are shaping the future of aviation. In honor of International Women's Day, we sat down with María Sol Rau and Christina Martens to discuss their experiences, challenges, and hopes for the future of women in aviation. What’s one piece of advice you’d give to a woman considering a career in aviation but unsure if she belongs? "Give yourself permission to belong, because you do. Aviation needs capable, determined individuals. Trust in yourself, step forward, and give others the chance to see your potential." - Maria "Just do it. Define your goals, and pursue them! Do not let yourself be discouraged by anyone else." - Christina You can find the full article by Electronic Specifier Ltd here: https://lnkd.in/eAFf_TYA #IWD2025

By the early 2030s, we expect over 10 million annual flights. This would lead to a baseline traffic scenario of up to 183 million tons of full-flight CO2 emissions from all flights. Achieving our climate goals demands immediate, substantial emission reductions in aviation. EASA’s European Aviation Environmental Report 2025 underscores this, featuring hydrogen-powered aircraft like our HY4 and its groundbreaking liquid hydrogen flight. The report also champions market incentives, global cooperation, and airport action plans. We appreciate EASA - European Union Aviation Safety Agency for the feature, and you can read the full report here: https://lnkd.in/esbHaXEM

Sustainable aviation shouldn't cost the earth. We need to decarbonize air travel, but proposed solutions have massive price tags. While promising, SAF requires huge investments in production and energy, with costs for short-haul flights potentially reaching €830 billion in Europe and a staggering €3.5 trillion globally. Hydrogen presents a more economically viable alternative. Although it requires initial investment, its long-term costs are lower, making it a realistic solution for sustainable aviation. Hydrogen has the potential to revolutionize aviation. H2FLY's successful liquid hydrogen flight proves it. Let’s invest in the future of aviation—one that offers long-term sustainability, not just a temporary fix. Read more about hydrogen's role in sustainable aviation below. The Engineer UK

The future of flight isn't just about technology, it’s about people. Inspiring the next generation of engineers and aviation pioneers is key to building a zero-emission future. That’s why we were excited to welcome a graduating class from a local technical secondary school to our Stuttgart headquarters. From a behind-the-scenes look at our work in sustainable aviation to insightful discussions on industry challenges and opportunities, these students got a glimpse of what’s possible. A huge thank you to everyone who joined us. We hope to see you again—whether in the skies, in the lab, or driving the innovations that will define the future of flight.

Last month, our CTO, Prof. Dr.-Ing. Josef Kallo, joined Miquel Ros on the Allplane podcast to dive into the groundbreaking work we’re doing with liquid hydrogen in aviation. In this insightful conversation, Josef shared H2FLY’s key milestone moments over the past few years and explored why liquid hydrogen is the game-changer for enabling emission-free, long-range flights.

"Once considered a distant dream, hydrogen is on track to become a sustainable fuel sooner than many expect." In his latest article for International Airport Review, Prof. Dr.-Ing. Josef Kallo, dives into how airports can gear up for the hydrogen revolution. From modular storage solutions to strategic partnerships, discover what it takes to power the future of sustainable aviation.

Au revoir Paris! 👋 We had a fantastic time at Hyvolution this week, discussing the future of hydrogen mobility. Prof. Dr.-Ing. Josef Kallo gave a keynote on hydrogen in aviation showcasing H2FLY's achievements in hydrogen-electric propulsion technology and highlighting our successful collaboration with Joby Aviation last summer to demonstrate the potential for emissions-free regional travel. While we have the technology, scaling up green hydrogen production from renewable energy sources is crucial to achieving our mission. This is particularly important given the growing energy demands of other sectors. Thank you to everyone who attended!

The World Economic Forum Annual Meeting 2025. 🌍 The World Economic Forum returns to Switzerland on January 20-24, 2025, a global platform for tackling the world’s most pressing challenges, including climate change. At H2FLY, we’re excited to see what commitments and innovations emerge from this year’s discussions and how they’ll shape a greener, more sustainable future. We’re dedicated to advancing hydrogen-powered aviation and look forward to seeing how global leaders and changemakers push for meaningful progress at #WEF25. Who knows, we expect soon, world leaders will be arriving in hydrogen-powered planes? https://lnkd.in/gSxtehDm

It’s 2025, so what’s next for aviation? We sat down with our Co-founder & CTO, Prof. Dr.-Ing. Josef Kallo, to talk about what’s ahead for sustainable aviation this year. See what he has to say below: - SAF is a short-term fix. While Sustainable Aviation Fuel (SAF) can cut emissions now, its reliance on large amounts of renewable energy means it’s not a long-term solution. - Hydrogen is the future. Hydrogen-powered planes are on the horizon, but building the infrastructure is complex, expensive, and highly regulated. That’s why we need to start preparing today, not later. - Policy needs to keep up. By 2025, policymakers need to set clear regulations to give airports and engineers the head start they need to make hydrogen aviation a reality. Put your thoughts below and let us know what progress you'd like to see across the next twelve months.

Get to know Michael Lang, one of H2FLY’s talented Systems Engineers, who’s turning his lifelong passion for aviation into a reality. Fun fact: back in 2016, Michael spotted the HY4 on the apron at Stuttgart Airport and started following H2FLY’s story. Fast forward to today, we're proud to have him on the team, helping bring our vision of zero-emission aviation to life. How did you get into aviation? While most kids were fascinated by cars, I was busy building remote-controlled planes and designing my own experimental aircraft. This passion naturally led me to pursue aerospace studies at the University of Stuttgart, where I worked with four friends to win the DLR NASA Design Challenge 2019. What does your role entail? I support the development and integration of complex fuel cell systems into aircraft prototypes, paving the way for real-world zero-emission flight demonstrations. Problem-solving, creativity, and cutting-edge tech make every day exciting. What excites you most about your role? - Pioneering sustainable aviation alongside partners like Joby. - Being part of a young, motivated team at the forefront of innovation. - Seeing my dream of emission-free flight become a reality. What’s your favorite moment so far? I’ll never forget the HY4’s endurance flight record: three hours of majestic flying. I was in the chase plane, just meters away, witnessing history in the making. Moments like that make every challenge worthwhile. Such a fantastic story, thanks for sharing it with us, Michael. We're glad to have you on the team!
