Some of the largest-scale solutions, such as pumped hydroelectric storage or compressed air energy storage, are limited by the available geography or geology.

Storing energy under water: compressed air energy storage has been successfully deployed, but the expense of finding suitable underground sites has limited its use. Recent tests have shown that bags of air anchored deep under water can store energy close to major cities

The UK currently has 2800 MW of electricity storage capacity in the form of pumped hydroelectric storage. According to National Grid we will need 8000 MW of electricity storage capacity by 2025 if the penetration of wind power in the network is 30%.
