the greek reporter website reported on september 25 that a swiss company has built a supersonic hydrogen-powered passenger aircraft that can shorten the flight time from the united states to china to three and a half hours. according to reports, the company has been testing supersonic hydrogen-powered passenger aircraft in the past few years and has successfully tested them.

the report mentioned that according to the flight speed of the passenger plane, commercial airlines will greatly improve the carrying efficiency in the future. the swiss company said that the technology of supersonic hydrogen-powered passenger aircraft can shorten the flight time from frankfurt to sydney to 4 hours and 15 minutes instead of the current 20 hours, while the flight from frankfurt to shanghai, china will only take 2 hours and 45 minutes, 8 hours shorter than the current journey.

according to the report, the company stated that the current total investment in the supersonic hydrogen-powered passenger aircraft project has reached 12 million euros (approximately rmb 93.92 million). with a speed of more than 5 times the speed of sound, passengers can reach another part of the world in 3 to 4 hours. there is no need to stop at one end and there is no noise.

the american science news website scitechdaily reported that hydrogen-powered flight will provide new opportunities for the development of the aviation industry, and hydrogen-powered flights will also completely change air travel. with the rapid development of science and technology, almost all flights will be able to meet the conditions for using hydrogen power by 2045. some countries may start flying hydrogen flights before 2028, and hydrogen energy will be used as flight power on a large scale around the world. probably until 2050 or so.

the report pointed out that hydrogen energy, as a green and low-carbon energy source with abundant sources, is of great significance to reducing carbon dioxide emissions and achieving carbon peak and carbon neutrality goals. it is known as the "ultimate energy of the 21st century."
