Gravitational energy storage is a tricky thing. To store 100 MWh, this installation needs about 9000 of those concrete blocks, and just the manufacture of each of them produces as much CO2 as China’s average per capita. Never mind the structure, equipment, space etc. To capture 25 MW of power, it needs to lift one every two seconds up to the top, vice versa to release power.
