Barbegal Energy is named after the oldest known large-scale Roman water mill complex in Barbegal, France. At Barbegal, the Romans built an industrial scale flour mill with 16 connected water wheels. They did this almost two thousand years ago.
World’s Largest Battery
When most people think of batteries, they think car batteries or maybe a Tesla Powerwall. But for grid scale energy storage, one technology dwarfs everything else: pumped hydro. Pumping water uphill and running it back down via a hydro-turbine accounts for over 90% of the world’s energy storage.
