Airbus to test hydrogen-fueled engine on A380 jet

Considering how dangerous hydrogen is, would you want to have it on board when you are airborne? Everything in touch with H2 would have to be exchanged pretty regularly because of hydrogen embrittlement. Imagine a leak. And hydrogen is much harder to make into a liquid and to keep liquid. If airlines really want to go carbon neutral they have an easy option. Use biomethane. It’s safe, it’s easy to procure and its a hell of a lot cheaper too. But why do the cheaper, safer, technologically more mature thing when you can play with the hard stuff?
