Thanks for that information Enrique. The question has to be asked - how are they managing to store their overcapacity?
Vietnam, when it over-produced solar farms, had way too much energy to connect to grid all at once, so the solar instalation investors, who had been incentivised by government promises to provide lucrative rewards for solar energy connected to grid, were disappointed, by the government only taking a small fraction of the energy offered.
The solar farms had no method of storing energy between peaks of daylight, at night etc, so they had no way to store energy as backup, or to sell in stored form.
Hence why at the time I was writing to show they could use hydrogen generation to capture at least some of the energy unsold to government, in a saleable form - hydrogen fuel.
I don't know if they moved to that, but China is just as advanced in hydrogen tech as it is in solar, so it's likely using hydrogen to capture and store excess energy from oversized solar, because it won't be by batteries.
On wind, I am surprised if it still fratures highly in installation, because with enough solar, wind isn't required, and wind is more expensive than solar, so why bother with wind when solar can deliver everything needed.
Maybe they are worried about Western Geoengineering, in which case wind might not be a bad idea.
So I hope we would not fall into the trap of overproducing just raw wind and solar, with no way to grab and store unused energy, we should learn from the experiences of businesses in Vietnam as well as China.
