How Are Hydrogen-Powered Aircraft Revolutionizing #ZeroEmissionAviation? Hydrogen-powered aircraft represent a promising leap towards zero-emission aviation. By using hydrogen as fuel, these planes—whether through combustion or fuel cells—produce only heat and water, thus eliminating #greenhouse gas emissions. With ongoing research addressing #hydrogenstorage, safety, and costs, the aviation sector is poised to embrace this clean energy solution for a sustainable future.

The aviation industry is on the cusp of a significant transformation, with innovative technologies like hybrid-electric and battery-electric propulsion set to play critical roles. Current projections suggest that relying solely on sustainable aviation fuel won't be enough to meet the goal of net-zero carbon emissions by 2050. Learn more: #aviation #aerospace

How Can #HydrogenFuelCells Transform Aviation's Environmental Impact? Hydrogen has emerged as a promising contender for mitigating aviation's carbon footprint, thanks to its high energy density and zero-emission potential. Fuel cells convert #hydrogenandoxygen into electricity with water vapor as the only byproduct. Current research focuses on improving the efficacy, durability, and efficiency of these systems to meet aviation's stringent operational demands.

We believe there is a massive need for people to reconnect physically without a drop of fossil fuel or carbon dioxide, not being captured, so what path Sustainable Aviation takes is up to us providing the technology and fast.

Airbus VP, Zero Emission Aircraft, Glenn Llewellyn, recently sat down with our Founder and CEO, Val Miftakhov, and provided insights into the #ZEROe program activities, covering 3 main areas: developing the ecosystem (including delivering the large quantities of hydrogen needed at airports) and propulsion technology development (e.g., making fuel cell systems lighter and more power-dense), among a number of other topics.✈️ Check out the snippet in the video or hear from Glenn on what Airbus is working on underneath the ZEROe program here: https://lnkd.in/egwaaPi7 #zeroemission #hydrogen #aviation

The results of a European study into the impact of a widebody jet flown with 100% sustainable aviation fuel show a substantial 56% reduction in the number of contrail ice crystals produced by unblended SAF compared to Jet A-1 fuel, reports Tony Harrington for GreenAir News. The project, involving Airbus, Rolls-Royce, the German Aerospace Center (DLR) and SAF producer Neste, was the third stage of the Emission and Climate Impact of Alternative Fuels (#ECLIF) programme, with in-flight and ground emissions tests taking place in 2021. They worked together to quantify the reduction in engine soot particles produced by a Rolls-Royce powered Airbus A350 fuelled by Neste and trailed by a DLR research aircraft. In certain weather conditions, airborne vapour freezes around soot particles emitted by aircraft engines, creating cloudy canopies of ice crystals which can trap heat in the atmosphere. #sustainableaviation #sustainableaviationfuel #aviationnonco2 Mark Pilling Christiane Voigt Hartwig Hagena Mark Bentall Alexander Kueper Alan Newby Philippe Gmerek Falk Dambowsky Heiko Stolzke Matteo Mirolo Florian Allroggen Steven Barrett Vincent de Haes Carlos López de la Osa Dimitar Nikov Marc Shapiro Jason Taylor Estuaire Jonathon Counsell Adam Durant International Air Transport Association (IATA) Marie Owens Thomsen Jill Blickstein Andrew Chen Dr. Alejandro Block Hemant Mistry Sarah Wilkin Roger Gardner https://lnkd.in/eD357-ap

✈️ Airbus, alongside Rolls-Royce, DLR, and Neste, successfully conducted the world's first in-flight study using 100% sustainable aviation fuel (#SAF) on both engines of a commercial aircraft. The study revealed a significant reduction in soot particle emissions* and contrail ice crystals**, which can decrease aviation's climate impact by 26%. This breakthrough demonstrates SAF's potential to mitigate both CO2 and non-CO2 emissions, marking a crucial step towards decarbonizing air transport. *Soot particle emissions are tiny, black carbon particles released into the atmosphere from the incomplete combustion of fossil fuels and biomass. These particles can contribute to air pollution, climate change, and respiratory issues in humans. **Contrail ice crystals are clouds formed from the water vapor emitted by aircraft engines at high altitudes. When these water vapor molecules freeze around tiny particles in the exhaust, they form ice crystals, which can sometimes persist and spread out, potentially affecting climate by influencing cloud cover and reflecting sunlight. #SustainableAviation #SAF #Airbus #AviationInnovation For more details, read the full press release (https://lnkd.in/eEJXw5mq).

How feasible is hydrogen-fuelled aviation? Researchers are exploring hydrogen-powered aviation to cut aviation CO2 emissions by up to 90 percent, whilst highlighting key design and infrastructure challenges. Learn more: https://lnkd.in/eX8Ppt2J #hydrogen #aviation #sustainabletransport #aerospace

The aerospace industry has made significant progress in improving fuel efficiency - today’s commercial aircraft are around 20% less polluting than those of a generation ago. But as passenger demand continues to grow, these efficiency gains are being outpaced, and aviation’s global emissions are rising. At Cranfield Aerospace Solutions, we believe it’s time for a new approach. To truly address aviation’s environmental impact, we need to stop emitting CO2 from aircraft entirely. This means a revolution, not just evolution, in propulsion and aircraft technology. As 2025 begins, we’re focused on developing hydrogen-powered aircraft and propulsion systems that will help drive this change. With nearly 30 years of experience providing safe and certified aerospace solutions, we’re taking a phased approach to innovation, working closely with regulators, partners, and industry stakeholders to create technologies that are effective, practical, and safe. The road to zero-emissions aviation is a collaborative effort. By working together, we can ensure air travel remains a vital part of our lives while taking critical steps to protect our planet for future generations. 🌟 🎥 Watch our brand video and join us as we chart the flightpath to cleaner skies. 🔗 www.cranfieldaerospace.com #ZeroEmissionsAviation #HydrogenFlight #CleanerSkies #HydrogenAviation #HydrogenTech #FutureFlight #CranfieldAerospace #SustainableAviation

The great hydrogen for aerospace dilemma, H2 tank weight. A Toyota Mirai has a 5kg tank which weighs a whopping 89kg empty. The original tank was 95kg empty, so despite millions in research they only managed to shave of 89kgs and sold in total around 22000 cars in 11 years, when they sold 140000 BEVs in 2023 alone, despite management being anti-battery EV. To be fair when it comes to sales, the logistics are an issue, as it will be for civilian aviation and the military. So can the aerospace industry do better? As I see it the bulk of the fuel is stored in an aeroplane's wings, so the wings will be very heavy if made from the same material as the Mirai's tanks and tank pods will put a lot of strain on the wings, that is if any CAA/NAA approve the tank pods, while H2 tanks in the fuselage will eat up a lot of payload. The question has to be why aeroplanes and not helicopters, where all the weight is in the fuselage and you are replacing fuel tanks and a turbine engine with an H2 tank, a fuel cell and electric motors?
