Definition:
The process of storing natural gas in underground facilities to balance seasonal supply and demand.
Key Components:
- Depleted Gas Reservoirs: Repurposed natural gas fields for storage.
- Salt Caverns: Man-made underground chambers for high-pressure gas storage.
- Aquifer Storage: Uses porous rock formations to hold gas reserves.
Use Cases/Industries:
- Energy Security: Ensures reliable supply during peak demand periods.
- Price Stabilization: Allows storage when prices are low for later sale at higher prices.
- Industrial & Power Generation: Provides backup supply for utilities.
Advantages:
- Large Capacity: Stores vast amounts of natural gas.
- Supply Flexibility: Rapid withdrawal rates help meet demand spikes.
- Cost Efficiency: Uses existing geological formations, reducing infrastructure needs.
Challenges:
- Geological Constraints: Requires suitable underground formations.
- Environmental Regulations: Must meet safety and permitting requirements.
- Infrastructure Costs: Requires pipelines and compression facilities.
