To address these issues, a power generation system for pressure energy recovery at natural gas city gate stations is proposed and investigated. Firstly, the post-heating method is adopted and turboexpander is employed to convert the pressure energy into electricity.
The proposed compressed gas energy storage system will produce electricity upon withdrawal of the high-pressure gas that was previously injected by the electric-drive compressors. The CGES system also includes an aero-derivative gas turbine for a nameplate rating of 35 MWe with a primary energy efficiency of 42.4 percent.
Worldwide consensus of energy conservation and emissions reduction calls for effective and eco-friendly energy recovery infrastructures in natural gas pipe networks. However, a considerable amount of energy is abandoned by employing pressure regulators in existing city gate stations.
The advantage of this power generation technology is that it not only recycles the pressure energy of natural gas to generate power, but also utilizes the cold energy produced by the depressurization process of natural gas, which improves the utilization rate of energy, produces by-product CNG, and improves the economic benefits of the product.
The compressor station receives electricity from an electric power line that runs from PG&E’s Dairyland-Mendota 115 kV transmission line to the substation at the compressor site. When needed, withdrawal of the gas is extracted from the reservoir at an average flow rate of 542 MMSCFD.
Northwest Natural Gas Company’s Gill Ranch Storage facility in Madera, California, has two of the major CAES components already in place, namely the compressor train (comprising five units with variable frequency drives (VFD), inter- and after-coolers – basic fin-fan air coolers) and the storage space (depleted natural gas reservoirs).
