Introduction

The natural gas storage industry provides the service of storing natural gas for future use. Storage facilities help balance the supply and demand of natural gas, ensuring a stable supply during periods of high demand or production disruptions. These facilities store excess natural gas during periods of low demand and release it when demand increases. The services provided by this industry are crucial for maintaining energy security, managing seasonal demand fluctuations, and supporting the operational flexibility of the natural gas distribution network.

Main Segments Within the Industry

The natural gas storage industry is primarily categorized into three main segments, each with specific storage methods and applications.

Underground Storage Facilities

Underground storage is the most common method for storing large volumes of natural gas. It involves storing gas in natural geological formations.

Depleted Gas Reservoirs

Objective: Utilize existing geological formations that previously held natural gas.

Process: Depleted reservoirs are repurposed for storage by injecting natural gas into the formations, where it is stored until needed.

Example: The Rough storage facility in the UK, a large depleted gas field used for seasonal storage.

Aquifers

Objective: Store natural gas in porous and permeable rock formations that contain water.

Process: Natural gas is injected into aquifers, displacing water and creating a storage space. The gas is extracted when needed.

Example: The Spindletop storage facility in Texas, which uses an aquifer for natural gas storage.

Salt Caverns

Objective: Create storage space by dissolving underground salt formations.

Process: Water is injected to dissolve the salt, forming large caverns. These caverns are then used to store natural gas.

Example: The Mont Belvieu storage facility in Texas, known for its extensive salt cavern storage capacity.

Above-ground Storage Facilities

Above-ground storage involves storing natural gas in tanks or other surface facilities.

Liquefied Natural Gas (LNG) Storage

Objective: Store natural gas in its liquid form to save space.

Process: Natural gas is cooled to -162°C to convert it to LNG, which is stored in insulated tanks. It is regasified when needed.

Example: LNG storage tanks at the Isle of Grain terminal in the UK, providing storage and regasification services.

Compressed Natural Gas (CNG) Storage

Objective: Store natural gas at high pressure in above-ground tanks.

Process: Natural gas is compressed to a fraction of its volume and stored in high-pressure cylinders or tanks.

Example: CNG storage facilities used by transportation fleets for refueling CNG-powered vehicles.

Pipeline Storage

Pipeline storage involves using the natural gas transmission and distribution network to store gas temporarily.

Objective: Utilize the flexibility of pipelines to store natural gas.

Process: Adjusting the pressure within the pipeline network to store additional gas temporarily.

Example: Using line pack during off-peak periods to balance supply and demand within the pipeline system.
