Hydrogen has one advantage, it can be generated from excess energy on the grid
True, but to do that, you'll need much more hydrogen generating capacity, and much more solar/wind farms. And still, that doesn't cover the energy needs in winter.
I think you missed the point about storage, you can store hydrogen just as you store natural gas, it can be turned into liquid as LNG, it can be stored in pressure tanks it can even be stored in salt caverns. Or if you have the energy to spare you can simply transform it into methane gas, it's like one of easiest chemical reaction in the world, especially if you're in a pinch and you already burn coal.
What people do not realize is that we do not have the infrastructure for continuing to improve and benefit the most out of renewable energy. I mean sure there are people who are working their best, but we haven't done that globally yet and still pay oil companies tax brakes and such to keep it going.
Let’s face it, they are making tens of billions of dollars in profit while everyone else in the entire world suffers, it is the biggest crisis we have right now and they INCREASED their profit. All in all, more renewable energy and less oil usage will make sure that the world will never have to go through this situation and building an infrastructure to navigate into it will help a lot.
