Regarding hydrogen-fueled passenger aircraft, there are two major concerns facing the airline industry: growing amounts of CO_2 emissions to the upper atmosphere and continuously increasing jet fuel prices as petroleum sources are being depleted fast. Both of these problems could permanently be ...
Fuel cells would make sense only for general aviation and small commuter aircraft as their engine efficiency is less than half of large gas turbines, but not for usual single or twin-aisle airliners.[3] The efficiency of a hydrogen-fueled aircraft is a trade-off of the larger wetted area,...
Hydrogen Fuel Cells For Zero Emission Aircraft Whether powered by batteries or fuel cells, electric aircraft are considerably quieter than their jet-fueled cousins. Cost is another consideration, and that helps explain why Hydroplane caught the eye of the US military. The company centers its business...
Toshiba Corp. has been pioneering superconductor-based technology for the last 50 years. (Asahi Shimbun file photo) A groundbreaking partnership is taking off between Airbus and Toshiba Corp. to explore the potential of superconducting technology for the future development of hydrogen-powered aircraft. ...
“The aircraft offers a promising future for the commercial drone industry. It is a cost-effective solution for a range of wide-area rural applications, and is ideal for fleet operations.” FlyH2 is also looking forward to field trials with its partners in sterile insect technique releases, fa...

Rolls-Royce is testing liquid hydrogen pumps able to deal with the low temperatures and pressures needed for future hydrogen-fueled aircraft propulsion systems. Rolls-Royce is working with airline easyJet to develop hydrogen combustion aero engines. The engines will be suitable for u...
Airports need to start planning, designing and consulting now to be ready for the first hydrogen-fueled aircraft, which Jacob’s believes will be in service by 2035. The report suggests three ways hydrogen can be integrated into the fuel offered by an airport: liquid hydrogen d...
To enable system level feasibility studies of hydrogen fueled aircraft, a preliminary design model for aircraft liquid hydrogen tanks is developed for both foam and multilayer insulations. This model is then used to design tanks for a small regional airliner as well as a large long range transport...
tanks to cryogenic storage solutions that allow for compact hydrogen storage with minimum weight and maximum safety. These would be the crucial hydrogen technologies, assuring competitiveness across a needed range and performance characteristics for hydrogen-fueled aircraft compared to traditional aircraft. ...
