Liquefaction Project

Port Arthur Liquefaction Project

Port Arthur LNG, LLC is developing the Port Arthur liquefaction project to help meet global demand for LNG. The proposed liquefaction project would be a low-cost liquefaction facility providing a reliable supply of LNG to energy markets around the world.

The Port Arthur liquefaction project, as proposed in the Federal Energy Regulatory Commission (FERC) application, includes two natural gas liquefaction trains capable of producing, under optimal conditions, up to approximately 13.5 million metric tons per annum (mtpa), up to three LNG storage tanks and ancillary support facilities to liquefy and load LNG onto ships.

The project would use a portion of Sempra’s property along the Sabine-Neches ship channel in Port Arthur, Texas that provides direct access to the Gulf of Mexico.

Additionally, a 3-mile portion of Highway 87 between the Intracoastal Waterway and Keith Lake Pass, which extends to the community of Sabine Pass, would be relocated to accommodate the project and built to Texas Department of Transportation standards.

Bechtel has been selected  to be the engineering, procurement, construction and commissioning (EPC) contractor. Development of the Port Arthur LNG liquefaction project is contingent upon obtaining customer commitments, completing the required commercial agreements, securing all necessary permits, obtaining financing, incentives and other factors, and reaching a final investment decision.

The proposed project is designed to include:

  • Two natural gas liquefaction trains capable of producing, under optimal conditions, up to approximately 13.5 mtpa in the aggregate, or approximately 698 billion cubic feet of natural gas per year
  • Up to three liquefied natural gas (LNG) storage tanks
  • Marine facilities, including two marine berths for LNG vessel berthing and loading of LNG
  • Natural gas liquids and refrigerant storage
  • Feed gas pre-treatment
  • Truck loading and unloading areas
  • Combustion turbine generators for self-generation of electrical power

Strategic Location

The proposed project would be located along the Sabine-Neches ship channel, a strategic location near abundant natural gas resources.

  • Access to robust, North-American gas pipeline system
  • Large contiguous site with large laydown areas
  • Channel is maintained for deep draft vessels (Q-Max)

Permitting Approvals

Port Arthur LNG and its affiliate PALNG Common Facilities Company have together filed an application with FERC seeking authorization to site, construct and operate the Port Arthur liquefaction project.

The project’s applications to FERC are important milestones in the development and review process for the proposed natural gas liquefaction project and related pipelines.

In addition to FERC, the Department of Energy (DOE) is the federal agency responsible for permitting the exportation of natural gas.

In April 2019, Port Arthur LNG received authorization from FERC to site, construct and operate its natural gas liquefaction-export facility and in May 2019, received authorization from the DOE to export approximately 13.5 million tonnes per annum (Mtpa) of U.S.-produced liquefied natural gas (LNG) to countries that do not have a free-trade agreement (FTA) with the U.S.

Beyond the FERC and DOE authorizations, the project will also require permits and approvals from the U.S. Army Corps of Engineers for impacts to wetlands, as well as from state and local agencies.
