Aerospace company Universal Hydrogen recently conducted the largest trial of a liquid hydrogen-powered aircraft powertrain, which could pave the way for carbon-free flights in the future. While electric-powered flights have severe limitations, hydrogen fuel cells hold much more promise as a carbon-free alternative for regional flights. Universal Hydrogen has been working on a liquid hydrogen system to fuel a higher energy powertrain that aircraft can use for their regional flights. The system is about the size of an air freight container and can be swapped into hydrogen-powered aircraft using the same equipment for cargo shipments✈️ Stay updated on more #energynews like this, click the link below and sign up for our forum 👇 https://bit.ly/3Rljnow #powerheads #powerengineering #engineering #engineeringforum #students #engineeringstudent #engineering #engineers #energynews #aviation #carbonfree #hydrogen #futureofflight #cleanenergy

As people are discovering, #hydrogen is a tricky molecule to handle. Special Materials need to be trialed and tested for the effects of exposure to hydrogen, then they need to be classified for aviation use. Procedures for refueling need to be reviewed and changed, ATEX and F&G regulations changed and applied where they were not previously. Monitoring and detection for safety of passengers and crew both onboard and support staff on the ground need to be developed and proven. Then there's the infrastructure to deliver the molecules to the airport and manufacture them in the first place from fresh, clean, drinkable water... that's a lot to do, and who's paying? We're likely to see peak Aviation use this decade, just look at the numbers of planes sold last year. If that keeps up, where will the Terawatts of energy potential come from? Asking for a friend.

PowerCell Group has entered an agreement with an Australian aviation company to conduct a concept study for a vertical take-off and landing (VTOL) aircraft with minimal emissions. This study includes an order valued at SEK 7 million for engineering work to specify the hydrogen fuel cell system for the aircraft’s powertrain, with the goal of developing prototypes for commercial use. The electric VTOL segment is an emerging market with vast potential for commercial applications. Hydrogen fuel cells are particularly well-suited for VTOL aircraft, given their high energy-to-weight ratio. This allows hydrogen-electric VTOLs to achieve significant payload capacity, impressive range, minimal emissions, and low noise levels. https://lnkd.in/d3_E_E3d #greenaviation #greenh2 #greenhydrogen #greenfuture

easyJet and Rolls-Royce have kicked off a series of “ground-breaking” hydrogen research tests as they look to place themselves at the forefront of the development of hydrogen combustion engine technology. Rolls-Royce identified fuel combustion, fuel delivery and fuel systems integration with an engine as the three main challenges that must be solved to ensure hydrogen can be used in aviation. The pair have already proven fuel combustion, with this latest batch of research looking into fuel delivery. #hydrogen #aviation #liquidhydrogen #netzero

✈ Revolutionizing Aviation: Trelleborg Sealing Solutions Joins Airbus in #Hydrogen Sealing Innovations 🛫 Trelleborg Sealing Solutions has partnered with Airbus to develop hydrogen sealing applications, supporting the mission to deliver a hydrogen-powered commercial aircraft by 2035. - Trelleborg is creating safe and reliable seals for the hydrogen propulsion systems of the ZEROe concept aircraft, enabling Airbus to explore various configurations and hydrogen technologies that will shape the future of low-carbon flight. Torben Adrian Andersen, Trelleborg Director Aerospace, said: "We are proud and excited to be working on such an important project.", adding "Air travel is responsible for around 2.5% of greenhouse gas emissions, and we are delighted to be helping Airbus deliver its ambition of decarbonizing air travel, which matches our goal to lower our carbon emissions in line with the Paris Agreement. Hydrogen provides an opportunity to make flying a more sustainable mode of transport. But as the smallest molecule typically used in cryogenic conditions, it presents significant sealing challenges. Trelleborg is bringing all its experience as a leading global supplier of sealing solutions to the ZEROe project." - To develop the necessary technology, a high-pressure cryogenic test rig has been designed and built at the Trelleborg Sealing Solutions Bridgwater facility in the UK. Bridgwater is known as a center of excellence for Wills Rings® and Variseal® spring-energized seals, widely used by the oil and gas industry, ideal for developing seals for fluid or gaseous hydrogen that will power future Airbus aircraft. Peter Bashford, Product Leader at Bridgwater, said:  - "Initial testing of Wills Rings® demonstrates they provide near 100% sealing of gas in cryogenic conditions. Trials of more flexible polymer materials at low temperatures are continuing, mapping their material properties for the finite element analysis studies required for each design. Initial testing has yielded several very promising sealing concepts, and we are confident we will deliver a leap forward both in the understanding of cryogenic sealing technology." Airbus is developing a variety of low-carbon propulsion technologies and configurations that will shape the future of air travel. Whether the next hydrogen-powered aircraft is powered by an electric fuel cell, direct combustion gas turbine, or a hybrid combination of both, these concepts all use hydrogen as the base fuel source. While the environmental benefits of using hydrogen as a fuel source are well documented, the technical challenges that need to be overcome to achieve a practical and #safe solution are only now becoming apparent. #Aerospace #Innovation #HydrogenTechnology #CleanEnergy #SustainableAviation #NetZero2050 #ParisAgreement #FutureOfFlight #Airbus #Trelleborg #ZEROe #ClimateAction #GreenAviation #CryogenicSealing #Decarbonization #LH2

Hydrogen fuel cell and aircraft electrification technologies developed by Japan’s IHI will be further refined through projects initiated by the country’s New Energy and Industrial Technology Development Organization (NEDO). The two initiatives relate to Japan’s Next-Generation Aircraft Development Project and fall under NEDO’s Green Innovation Fund, says IHI Aerospace. IHI will develop a 4MW-class fuel cell propulsion system that could power a future 40-seat regional aircraft The hydrogen fuel cell propulsion system was developed by IHI Aerospace and under the next step it will scale this up to ”a four-megawatt-class” powertrain, says IHI Corporation. “This zero-emission set-up would power an aircraft with more than 40 seats and feature a cruising duration of more than three hours.”  An image released IHI shows a large #hydrogen containment vessel in the rear of an aircraft powered by four electric motors. The University of Tokyo will furnish technical studies and international standardisation efforts to the project, which will run from 2024 to 2029. The work will see IHI explore the design of the zero-emission propulsion system, including the optimal layouts and specifications of every component. A key goal will be for the system to demonstrate operation for over 3h on the ground. NEDO has also selected IHI’s electric power control and thermal air management system for further exploration. This will see IHI develop the “world’s most powerful electric aircraft turbo compressor”, it says. #Electrification #LH2 #LiquidHydrogen #zeroe #sustainableaviation
