upscaled green hydrogen market

That’s been the talk in town for 40 years now. Green hydrogen has never gotten beyond proof-of-concept.

The fact that we seem to constantly discuss nuclear vs. renewables is proof that it’s mostly lobbying bullshit.

Sadly, it’s because the political green parties available to me are anti-nuclear.

It’s either renewables+short-term storage+long-term-term storage or renewables+nuclear+long-term storage.

Why is nuclear+short term storage not an option, according to you?

Your estimation goes way off because you still believe lithium ion to be the only viable solution. By now Sodium-Ion batteries are already installed even in EVs and can be produced without any critical resource like lithium.

And then of course there are all the other storage solution. Like I said, there even are storage solutions like concrete balls. Successfully tested in 2016, here an article from 2013.

By now it wouldn’t be wise to stifle this enormous emerging market of various technologies by using expensive, problematic technology (not just because the biggest producer of fuel rods is Russia).

Another problem arises when you’re generation 63.688 after today and still have to keep maintaining deadly waste from nations that don’t exist anymore, because they produced “cheap” and “clean” energy for a couple of decades.
Come on, Jesus died like 2000 years ago, this stuff will haunt us for centuries. Arguing in favor of something this unpredictable is just selfish, stupid and shortsighted.

The watthours is what gas is for. Germany’s pipeline network alone, that’s not including actual gas storage sites, can store three months of total energy usage.

…or at least that’s the original plan, devised some 20 years ago, Fraunhofer worked it all out back then. It might be the case that banks of sodium batteries or whatnot are cheaper, but yeah lithium is probably not going to be it. Lithium’s strength is energy density, both per volume and by weight, and neither is of concern for grid storage.

Imagine bridging even a short dunkelflaute of 2 days.

That’s physically impossible for a place the size of Germany, much less Europe.

The fossil industry, which earns 1 billion dollars a day since the 1970s, won’t go down without a fight. They are very powerful, able to start wars and overthrow governments. These fossil destroyers know they are dying, but they will fight back to make money as long as possible. The best we can do is drain their business model by going renewable, and fast. Nuclear is not an option anymore, they know that as well, it’s already way too expensive. But they use it anyway to buy some time. Making more money while we are debating instead of building renewables and batteries like our lives depend on it.
I always imagine Henry Ford after building his first cars. People would laugh at him: “And how do we fuel these?! You want to pave every road and build a web of gas stations all over or country? You are insane!”
