Gravity storage involves lifting heavy masses using excess electrical energy during off-peak hours and allowing them to fall back down to generate electricity when needed. This method uses mechanical means instead of chemical reactions.
Addressing long-duration storage needs where traditional battery systems may not be cost-effective or feasible due to size constraints or environmental concerns.
Excess power from renewable sources or other times is used to lift a large mass (like blocks or weights) into a higher position using cranes or shaft hoists. When energy demand increases, the masses are allowed to fall, driving generators and producing electricity.
Requires specialized cranes, shafts, and composite blocks. The materials must be durable enough to withstand repeated lifting and lowering cycles over many years.
Construction involves setting up the storage tower or shaft, installing cranes or hoists, and preparing the composite blocks. Testing of the system follows before operation begins.
