and that probably means completely redesigning the plane. everything will be shrunk. some parts of the engine, of the fuel cell, will be sitting inside of the nacelle, and also the storage tank, which is, uh, going to be probably the largest, uh, you know, piece of equipment they will actually bring outside, 0k? right. so either on the side of the fuselage, or we will hang it on the wing. making everything fit isn't the only challenge, though. you need to have the maintenance and repair organisation. the whole process needs to be certified. we need to provide the hydrogen infrastructure to the, uh, to the aircraft. zeroavia has a plan for that. in its vision, hydrogen would be produced on site at airports using renewable energy before being processed and transported out to the plane. but what about the cost of all this? at the moment, liquid hydrogen is significantly more expensive
