The tldr says 72% efficient. If it can store excess solar or wind from times they are not in use and release at times of higher demand, it should be great.
Better is always on the road to perfect.
Yeah that isn't as horrible as I had initially thought, though its still not great
You are right though something is better than nothing, but I wonder how this facilities cost compares to an equivalent battery storage facility
In all of this, we need diversity. Diversity of generation sources (solar, wind, tidal, etc). Diversity of storage (Chemical batteries, compressed air batteries, pumped hydro, etc). Each will have different sweet spots; cost vs reaction time vs capacity vs efficiency.
Try not to dismiss a technology just because it's not the whole solution. Nothing ever is. They all contribute a part to the big picture.
