#ALRIGH2T aims to develop and test innovative technologies and processes for refuelling liquid hydrogen aircraft in real airport conditions, with the goal of reducing the aviation sector’s environmental impact. Emphasizing safety and standardization, ALRIGH2T strives to be a reference in the transportation sector, aligning with Clean Aviation and Clean Hydrogen Partnership objectives to advance industry standards. Hydrogen-based propulsion has the potential to be a significant part of the propulsion technology mix in the near future, aiming to achieve climate-neutral aviation by 2050. Combustion of hydrogen could reduce the climate impact by 50-75% per flight compared to kerosene-based engines, while fuel cell-based propulsion has an even greater estimated impact reduction (75-90%). However, the development of innovative LH2-based solutions presents many new challenges that ALRIGH2T will try to address such as: 1. AVAILABILITY OF LH2 Develop more facilities to turn into liquid to ensure the presence of LH2, while also establishing an efficient global system for transporting, storing, and distributing LH2. 2. RELIABLE LH2 SYSTEMS Develop reliable, efficient and cost effective system for the supply and management of large amounts of LH2. 3. ADAPTATION FOR LARGER AIRCRAFT Capability to modify current airport ramps to accommodate larger aircraft. 4. SAFETY STANDARDS Ensure the safety of all components and systems for aviation use. 5. MATERIAL COMPATIBILITY Address relevant material compatibility issues in the presence of deep-frozen hydrogen 6. GROUND VEHICLE MOVEMENTS Explore the potential of leveraging liquid fuel handling capabilities with compressed hydrogen for ground vehicle movements to promote a hydrogen-based ecosystem at airports 7. REGULATORY LANDSCAPE Navigate the early stages of regulatory development for hydrogen refuelling infrastructure

In the latest in our series of future aviation trends, Chris Ellis considers the latest technical developments involving hydrogen in the large aircraft sector. #hydrogen #HydrogenNow #H2View

Some interesting findings here, overall some impressive numbers, with only little mention of the added aircraft weight from handling liquid hydrogen - if at atmospheric pressure, would be -252C and need for some onboard cryogenic equipment - am unsure, since there is no real re-liquefaction for Hydrogen, with over-pressure usually managed via vent or combustion ( in industry via flaring). and secondly, the need for still some scepticism that production and supply costs of Hydrogen can be as low as the reported figures. But overall, the blended wing design seems to provide the needed added volume to manage the low volumetric energy density...

Perhaps we need to accelerate ate #sustainableaviation as this campaign (see comment below) is set to only start to question the future of aviation and the #co2 emission and #nonCO2 emissions and the impact on our planet 🌍 What we need to do is accelerate the #TrueZero solutions like Fluxart’s superconducting motors with green liquid hydrogen. #aviation #ministry #climateemergency #badvertising Dr Veronica Wignall, Adfree Adfree Cities Emilie Tricarico, Badvertising www.badverts.org

Eurocontrol white paper emphasizes why industry hopes are pinned on alternative fuels: "we are, unfortunately, a long way from being able to use technologies such as batteries, fuel cells, hydrogen, methane, ammonia before several decades for any large-size aeroplane" "Just under 10% of flights from the EU27+UK area are longhaul (i.e. flying more than 3,000 km), but these account for over 50% of all aviation CO2 emissions. Game-changing technologies such as batteries, fuel cells, hydrogen, methane, ammonia or solar energy? This paper takes a hypothetical scenario – a large widebody flying from Paris to Singapore – and assesses how much time, energy and cost it would take to perform that flight, and what that would entail in technical terms, for each new technology. The answer in each case is that we are, unfortunately, a long way from being able to use any of these technologies before several decades for any large-size aeroplane."

Complete Guide To "Zero Emission Aircraft" A Comprehensive (PDF) Guide: (https://lnkd.in/ddG2KQbd) Rapid advancements in battery and propulsion technologies are propelling the zero-emission aircraft market growth. Breakthroughs in electric propulsion and energy storage systems contribute to the development of more efficient & viable electric aircraft, fostering innovation and attracting investments in cleaner, sustainable aviation solutions. For instance, in July 2023, DANX Carousel Group launched Electron 5, an electric cargo plane. This battery-run aircraft aims to facilitate zero-emission point-to-point air freight deliveries across Europe. The aviation industry is increasingly focusing on hydrogen fuel cell technology as a promising alternative for zero-emission aircraft propulsion. Hydrogen fuel cells offer a clean and efficient power source, producing electricity with water vapor as the only by-product. This growing focus reflects a commitment to exploring diverse sustainable energy solutions and addressing the challenges of long-range, zero-emission flight through advancements in hydrogen fuel cell integration.

“Decarbonization is the aviation industry’s existential challenge,” Anna Goranson, chief administrative officer of Universal Hydrogen (UH2), said. “Exponential traffic growth has made aviation one of the fastest-growing sources of greenhouse gas emissions, a trend which is unsustainable. We’re building the end-to-end value chain to enable true zero-emissions commercial services as early as 2025, ushering in a new golden era of flight.” Take a look at this SWE Magazine article that takes a look at the issue of CO2 emissions from aviation: https://bit.ly/46G207i #SWEMagazine #Engineering #Aviation #GreenhouseGas #Decarbonization #ZeroEmissions

I do not follow closely what the airplane industry is doing in their #decarbonisation efforts, mainly that there are some symmetric challenges to #shipping. The article gives a really nice overview of what is happening in the space of hydrogen and fuel cells for small aircrafts. the article describes rather well were they are at, technological and supply chain issues as well as relevant achievements. My thoughts take me to reflect that there will be a healthy competition for the first molecules of #greenhydrogen (mainly from the hard-to-abate industries). Not really sure where shipping will be sitting in the pecking order but I can see a way forward through green corridors and inter-industry collaboration.
