Potential energy batteries are so fucking cool.
fwiw, chemical energy batteries (aka typical batteries) are also potential energy batteries.
I don't know a simple or correct label that differentiates batteries whose potential energy is gravity-dependent from batteries whose potential energy is chemical-reaction-dependent, but the concept of gravity-based energy storage absolutely is cool as heck.
Yes, they are cool and we have lots of them. There was plenty of oil from the USSR but some rather forward-thinking measures were made during the Cold War to ensure our energy self-reliance in case of a global conflict. Odd that Poland doesn’t even though they have similar amounts of coal.
Yeah it's weird, they are called gravity batteries but there's options for other versions coming down the pipeline.
Yes, our country built them wherever we could. The one I visited uses a lake in what is now a first-class national park zone. Whoops, they are now only allowed to create a 4 cm peak-to-peak fluctuation of the water level.
