We use gravity batteries in the UK. They work well and are pretty good at their efficiency. When you are creating massive systems they are made to last decades. There is always upkeep but it is the same with coal, gas and nuclear plants. All these renewables are far cheaper and far more cost effective than these power stations and for years the main problem has been that wind and solar cannot be used as base load, but with battery storage on a mass scale, thermal and hydrogen storage, we are now at a place where building out far more solar and wind than we need is viable and mixing in these technologies to provide base load and grid stability.

Hydrogen fuel cells also. Use the excess to make hydrogen which is simple to store and then use it as a fuel to burn when you have demand. These have started to be put at the bottom of wind turbines so they don’t need to be stopped when the wind is blowing but there is no grid demand.

All these systems help balance the grid too meaning these renewables can be used as base loads instead of dirtier base load generators like coal or gas fire stations.

Also the article states it is found in intels chips too. So not really any better if they had stayed on that pathway either

Ah yes. Lay claim to someone’s domain even though they had the company name first and you were sloppy. But you are big and think you can just bully your way through life.
