Rio Grande LNG - Project Overview

Project 2018-09-05T12:08:00+00:00

Rio Grande LNG (“RGLNG”) is a natural gas liquefaction and Liquefied Natural Gas (“LNG”) export project. The facility will be supplied with natural gas from a new natural gas pipeline, Rio Bravo Pipeline. More information on the proposed pipeline can be found on the Rio Bravo Pipeline overview page.

On March 20, 2015 Rio Grande LNG filed with the Federal Energy Regulatory Commission (“FERC”) to request entry into the Pre-Filing process. On March 23rd, the FERC assigned RGLNG docket number PF15-20, and the pre-filing process was initiated on April 13, 2015.

On May 5, 2016 NextDecade filed an application with the FERC to site, construct and operate both projects, formally beginning the lengthy NEPA review. The FERC assigned the projects new docket numbers for this process. The application and all future documents will be made available at the FERC e-library ( for public access. The FERC assigned Rio Grande LNG the docket CP16-454, and Rio Bravo Pipeline docket CP16-455.

Both the Terminal and Pipeline are regulated by a variety of federal (and state) agencies. One of the most important agencies that must approve the Terminal and Pipeline before they can be built is the Federal Energy Regulatory Commission (“FERC”).

The purpose of the Terminal is to provide natural gas liquefaction, export and vessel and truck loading services to third parties. The Terminal will receive natural gas through the Pipeline, treat the natural gas as necessary prior to liquefaction, chill the natural gas until the natural gas condenses and becomes LNG, store the LNG pending loading for transport, and load the LNG onto LNG vessels for export to other countries or (to a much lesser degree) onto trucks for transport to North American LNG fueling facilities owned and operated by others. The Terminal will be sited on approximately 1,000 acres of land along the Brownsville Ship Channel located in Cameron County, Texas, near the Gulf of Mexico. The approximate central coordinates of the Terminal site are as follows: Latitude: 26° 1’ N, Longitude: 97° 15’ W. A map of the site can be seen below.

RGLNG is seeking FERC approval for six liquefaction trains, each with a nominal LNG output capacity of 4.5 million metric tons per year (“mtpa”), using Air Products and Chemicals, Inc.’s propane-mixed refrigerant (C3MR™) technology. The Terminal will also have natural gas pre-treatment facilities, four (4) full-containment LNG storage tanks, and truck loading facilities. Marine facilities at the terminal will be located in or along a single pocket and will include two marine loading berths, capable of receiving and loading LNG vessels. Additional dredging will be required to create a turning basin situated adjacent to the loading berth area. The Terminal will also include: a ground-flare system (to safely and reliably dispose of vapor streams that occasionally may need to be vented), various structures (e.g., an administration building, a control room, a workshop, a warehouse, electrical equipment substations, and enclosures for other support infrastructure), and a guarded entrance as well as other security measures. A draft plot plan of the facility can be seen below.

Rio Grande LNG, LLC and Rio Bravo Pipeline Company, LLC are special purpose entities created to develop and operate the Terminal and Pipeline, respectively. The development effort is still in its early stages, therefore Rio Grande and Rio Bravo have yet to establish local offices outside of The Woodlands, TX; however, as project development progresses, we will open a local office and hire numerous employees on a long-term basis who will live and work in the area of the Projects.

Rio Grande and Rio Bravo are subsidiaries of NextDecade LNG, LLC, which currently provides staffing support for Rio Grande and Rio Bravo. NextDecade has assembled an industry-leading team with decades of experience successfully developing, marketing, building, and operating LNG facilities.

Rio Grande and Rio Bravo also rely on environmental, legal and technical consultants and engineers well known in the LNG industry, including: CH-IV International, Moffat & Nichol, Ecology & Environment, Inc., Fugro Consultants, Inc., and K&L Gates LLP.
