It has a place in heavy industry. But right now green hydrogen is very scarce and expensive. Until that changes, it will be somewhat boutique.

99% of the world's hydrogen comes from natural gas steam reforming. That's why the vibes are so weird, it's a fossil fuel industry distraction

It takes huge energy to produce, store and transport. Just use that energy directly. Calling hydrogen stupid was the only smart thing Elon Musk has ever said.

It can never work, the energy needed to make it is more then energy available from the H. It's like needing 1 barrel of oil to make 3/4 of a barrel of oil.

I'm a proponent of Hydrogen if for no other reason than I find it foolish for the transportation industry to place all of it's eggs in one basket.

I'm glad the ICE hydrogen engines have been coming out. Not because they're directly useful. Outside of an engineering challenge (which is perfectly fine), they have no purpose outside of some racing applications.

I like them because it flags people who obviously have no idea what they're talking about. They like ICEs for what it is. And I do actually get that; from an engineering perspective, there's a lot of fascinating things going on inside there. However, efficiency was already hydrogen's biggest weakness. Fuel cells are 40-60% efficient, and is only one part of the hydrogen chain. You're going to replace that part of a chain with something that has traditionally struggled to get 25% efficiency? Why? You're doubling down on hydrogen's biggest weakness. This is the opposite of min-maxing.

So anyway, if they bring that up as anything other than engineering and racing purposes, they're a moron.
