ZeroAvia, a trailblazer in the aerospace industry, is currently working on a groundbreaking hydrogen-electric propulsion system, poised to revolutionize air travel by powering the world’s largest zero-emission passenger aircraft. In a remarkable test flight conducted in January, ZeroAvia showcased the potential of hydrogen as a viable energy source for passenger transport. During this trial, a retrofitted Dornier 228 aircraft took to the skies above the company’s Gloucestershire headquarters for a ten-minute demonstration.
