Gas can be synthesised
When's that going to happen? Right after the green hydrogen revolution?
They've been saying that for decades. It isn't happening. It's just natural gas.
It's not technology it's physics
Sorry, I didn't think someone would deny the existance of dunkelflautes. It's currently happening in Germany. (1).
I don't think lithium ion is the only storage technology. I was using it for scale.
The most cost effective storage is pumped storage. But even that wouldn't reach the scale necessary.
6 MWh pumped storage proof-of-concept won't l, either.
is what gas is for
Wouldn't it be better to go fossil free. Given, you know, climate change. And the fact that the gas needs to be shipped all the way from the US.
That's physically impossible for a place the size of Germany, much less Europe.
Unless we use a different technology, that is not renewables + storage?
I hadn't made that connection. Thank you
How many fingers do you have?
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?
It's not just power that's needed (MW), also stored energy (MWh).
Germany consumes on average 1.4TWh of electricity a day (1). Imagine bridging even a short dunkelflaute of 2 days.
Worldwide lithium ion battery production is 4TWh a year (2).
It's also a funny sidenote that France, a country with a strong nuclear strategy, frequently buys power from Germany because it's so much cheaper.
Isn't that normal? The problems with renewables isn't that they generate cheap power, when they are generating. Today windmills even need to be equipped with remote shutdown, to prevent overproduction.
The problems arise when they aren't generating.
What would 130% grid uptime even look like? 475 days a year without blackout?
I think we're talking about different things.
Storage is a solvable problem
I'm not convinced it is. Storage technologies exist for sure, but the general public seems to grossly underestimate the scale of storage required to match grid demand and renewables only production.
Biomass and windmills perhaps
Dude. I had to revisit your comment. This is amazing.
Thank you 1000 times!!!!
