Fuel cell propulsion systems are not only being developed for unmanned aircraft, hydrogen is also increasingly becoming a topic in passenger transport. The US space agency NASA, for example, together with the engineering school of the University of Illinois, is constructing electric aircraft using liquid hydrogen and fuel cells.

Prof. Kallo presented HY4

Professor Josef Kallo has been working for years on realizing his dream: the use of zero-emission fuel cell aircraft in passenger transport. On Sept. 29, 2016, he came a huge step closer to his vision, when the first flight of a four-seat, propeller-driven and hydrogen-run airplane was completed successfully. During the World of Energy Solutions, Kallo talked about the flight, the technology used and presented “his” HY4 to all interested attendees.

A unique aircraft with a distinctive design and innovative engine technology – that is how one could sum up the features of the Hy4, which the German Aerospace Center (DLR) had already showcased at the World of Energy Solutions on Oct. 12, 2015. The new concept study was presented by project head Professor Josef Kallo, who had already been responsible for developing its predecessor.
