"the world's first experimental aircraft operating on hydrogen and later liquid natural gas"
- mikeyouse 4y agoThey likely left out some qualifier when reporting on the RR press release -- it was green hydrogen generated from tidal energy + electrolysis so I suspect something like "Rolls-Royce tests carbon neutral hydrogen-fueled aircraft engine in aviation world first" would be a more accurate summation.
- p_l 4y agoOrigin of the hydrogen doesn't matter to the plane, so it's rather a stretch to call it first.
