8-hour battery storage is operating in Australia and more is coming!
This 50 MW/400 MWh battery plant is a key piece of tech to reach nearly 100% RE.
It will mostly charge when solar generation is high and discharge when the sun goes down.

We burn ~100 million barrels of oil every single day. 🌍
The good folks at @rockymtninst.bsky.social have been saying we can cut that by 20% — without switching fuels, changing behavior, or retiring any infrastructure early.
We can. Here's how — and what it would cost.
