Royal Aeronautical Society's 'Greener by Design - 2023/2024 Annual Report'
As part of its ongoing efforts to promote sustainability in aviation, the Royal Aeronautical Society has published a report titled "Greener By Design." The report provides an update on the progress being made in the development of hydrogen-fuelled propulsion systems for aircraft.
Here's a summary of the key points from the report:
Hydrogen Option:
🔹 The report highlights the potential of hydrogen as a sustainable fuel source for aviation, offering a zero-carbon alternative to traditional fossil fuels.
🔹 Airbus plans to develop a 100-seat regional aircraft powered by hydrogen-fuelled propulsion have matured in the last year.
Challenges to Overcome:
🔹 Cooling systems required for extracting waste heat from fuel cells and exhausting it into the atmosphere pose potential weight and drag challenges.
🔹 Certification of 700-bar or Liquid hydrogen tanks under survivable emergency landing loads will be critical, given their location close to the passenger cabin.
🔹 High-temperature fuel cells are being explored as a means to improve overall system efficiency, but may impose other operational challenges.
Progress in Key Areas:
🔹 Hydrogen Fuel Cell Technology: Airbus has successfully tested a 1.2 MW hydrogen fuel cell and is working on developing an integrated fuel cell power generation system.
🔹 Tests: ZeroAvia will develop and certify an integrated fuel cell power generation system, including inverters, electronic components, a hydrogen tank, and fuel system.
🔹 Flight Testing: Universal Hydrogen Hydrogen unveiled a concept for a 100-seat electric airliner, which had a planned Entry-Into-Service in 2030 but since has folded due to financial raise from Private VC markets.
🔹 Industry Collaboration: The "Hydrogen in Aviation" partnership, involving easyJet, Rolls-Royce, Airbus, Ørsted, Bristol Airport, GKN Aerospace, and ZeroAvia, has been formed to explore the challenges of designing and operating hydrogen-fuelled aviation.
Overall, the report provides an update on the progress being made in the development of hydrogen-fuelled propulsion systems for aircraft, highlighting both the potential benefits and the challenges that need to be overcome.
