I think it is mostly people who are invested ($$$) in Lithium batteries who are so loud. It is honestly annoying.

Hydrogen (also including power-to-gas, e-fuels, Ammonia) is the only technology of its kind that we have; a way of storing energy compactly and long term, and also be able to transport it relatively easy.

It is also the only solution to have carbon-neutral aviation, and many industrial processes can also not be easily electrified.
