@MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis IIRC most studies show that long term storage is only a few percent of total energy, certainly well under 10%. So it is a viable option - if you can get past leaks, and other problems (e.g. the temptation to burn it, producing NOx pollution). And can store vast amounts of energy relatively cheaply.
Nuclear is of course a viable option. There are a few others e.g. iron-air batteries, or just building a lot more renewables than we need. Long range interconnectors help. Lithium is only helpful for short to medium term storage.
Re synthetic fuels, so far extremely expensive and limited scale. Might possibly be used for aviation in the long run (but it's easier just to fly less, and we still need a reliable, safe solution to the contrails problem). Maybe shipping too (possibly as ammonia).

In terms of filling in the gaps in #energy production we could do some fun maths. Imagine massive #renewable overcapacity and see what storage we need.
Just move the yellow and green lines up x3. This is a typical summer week but we could also look at winter months (less #solar more #wind?)
@MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis Well, California has done a lot of the work for you. Have a look at their charts, including multiple GW of battery storage.
Also the study I posted about Australia. There was another one but I lost it on the other place. You can get *most* of the way with a few *hours* storage, not weeks.
@matthewtoad43 @MattMastodon @BrianSmith950 @Ardubal @Pampa @AlexisFR @Wirrvogel @Sodis
Might be this one. (Haven't found him directly on Mastodon yet)
Shows how we can get by in Australia with just 5 hours storage. Uses real time data.
