"China is building an offshore wind farm potentially generating 40 gigawatts,"
A subtle but important difference to take into consideration when there is no wind.
Germany has 65 GW potential wind generating power but is currently only getting 8 GW. A measly 12%.

Offshore is more than twice as consistent than onshore though, I think it's something like 30% full load hours? So the 43 GWpeak might translate into somewhere between 12 and 15 GW I assume.

depends on location, size of turbines, spread of turbines, average wind speed at given height, etc.
on average, new offshore wind farms in the UK are already pushing beyond 40%-45% cf.

The article states the area chosen should give them around 45% utilisation on that 40GW.
This isn't their only renewable source that they are investing heavily in though.
Something that isn't reported on (that I've seen, anyway) is what China are investing in, in terms of grid scale storage.
It's pretty straight forward that the future is oversized renewable energy, along with massive amounts of storage.

Source? The only ones I know about are the redox flow batteries which are meant to supplement grid power during peak usage (night time).

There's there still called google you know. It's pretty much common sense that China would be investing heavily in just about every energy storage solution known to man. They have some of the largest pumped hydro, compressed air, redox flow, thermal storage in molten salt, gravity batteries, lithium ion, green hydrogen projects going on.

I was hoping for a comprehensive fact sheet like the one here

Believe it or not Google can be crap to do research on.

China does have something like that, but it's mostly in chinese. That's the issues with searching for info on chinese systems.

So which source were you asking for?
The claim that excess renewables + storage is the future?
If you have any amount of understanding in the energy sector, it's fairly obvious that's the future.
The biggest difficulty is being able to predict the weather in terms of providing the storage generation to overcome the intermittent nature of renewables - but there are already projects around the world working on that technology that are being completed and tested every day.
That's a very very quick Google, there's a lot more information on the WA governments Western Power distributor working in the renewable electrical grid space

8GW is also about 40% of the energy their coal plants produce. It's not "measly" at all.
