Should pipeline storage capacity be used for existing pipeline networks?

For existing pipeline networks the pipeline storage capacity is available with no upfront capital investment, so this capability should be utilized to increase the efficiency of the operation as much as possible.

How does a gas pipeline work?

Each combination results in different gas pressures within the pipeline, and accordingly different masses of gas stored in the pipeline, or amounts of linepacking. Therefore, pipeline operators have many options for how to operate a pipeline to achieve a desired gas throughput.

Do gas pipelines need linepacking?

The ability of pipelines to store gas by increasing their operating pressure, or linepacking, is a common operational practice used to mitigate future operational uncertainty. The optimal operation of a gas pipeline network considering linepacking is determined by weighing the trade-off between storing linepack and compressor power consumption.

What is pipeline physics?

Pipeline physics dictate that many combinations of inlet and outlet pressures are able to achieve a desired gas flow rate through a pipeline. Each combination results in different gas pressures within the pipeline, and accordingly different masses of gas stored in the pipeline, or amounts of linepacking.

Is energy storage possible in natural gas transmission networks?

J. Energy Resour. Technol. May 2022, 144 (5): 050904 (10 pages) This paper presents the possibility of energy storage in natural gas transmission networks using two strategies. Proof-of-concept calculations were performed under a steady-state assumption, and the more promising option was additionally modeled in a transient approach.
