I responded to a comment stating that excess storage can be stored in batteries: https://news.ycombinator.com/item?id=43249008 I'd suggest reading the comments people are responding to before calling them bullshit.

"only" 12 hours of storage is 30 TWh of storage, at the world's current electricity consumption rates. This is an immense amount of storage, amounting to decades worth of global battery production. And that's ignoring the fact that the vast majority of batteries are going to electric vehicles, not grid storage. It's true that battery production is growing, but electricity demand will similarly grow as fossil fuel use in transportation and industrial processes are electrified. Out of all of our fossil fuel use, electricity production is only ~40%. Not to mention, poorer countries are developing and will eventually start deploying refrigeration and air conditioning on similar scales as developed countries.
Let's say it is 30Twh a day in 2030 - you can calculate 50% less energy usage during night making it 20 TWh during daytime and 10Twh during night time.
This excludes large wind farms that add to base load if you average over the world. There is always wind somewhere around you.
Realistically if we reach 5Twh storage we are able to be >90% renewable.
Having 5Twh of storage is of course not an easy feat if estimates are correct we will have 6.5TWh battery production in 2030. If we amount for 10% of that used in grid storage we would need a decade for a 90%+ renewable grid.
There is no faster method. It is realistic.
> 12 hours of night time is not 30TWh The world is currently at 26TWh A DAY
From your link:
> The global electricity consumption in 2022 was 24,398 terawatt-hour (TWh)
24,398. / 365 is 66.8 TWh of electricity used per day. And again, that's current electricity consumption. Before industrial processes are electrified. Before poor countries adopt air conditioning at the same rates as rich ones. Before transport is fully switched to EVs.

That's not how th consumption curve works. Even in the summer, the ratio of daytime to nighttime energy use isn't so high. And in the winter it's inverted, with nighttime energy use exceeding daytime use.
why should I? I have no idea how fast adaption rate are, we can calculate what it would cost for the current grid to be feasible and work based off of that.
Ah yeah the magical 107 Twh hydrogen capacity. How far off is that? That's a pipe dream.
This is a plan for anything past 2050. I'm talking right now.
