Gravity-Based Energy Storage Systems
These systems store energy by lifting heavy weights (like concrete blocks or sand) to a height using surplus electricity. When energy is needed, the weights are lowered, generating electricity via turbines, offering a robust alternative to chemical batteries.
Why It Matters
This technology addresses the intermittency of renewable energy sources, providing long-duration, non-degrading, and environmentally sustainable grid storage. It could revolutionize grid stability and accelerate the transition to 100% renewables worldwide.
