TotalEnergies and Global Infrastructure Partners (GIP) are providing up to US$1.8bn in investment commitments to the fourth liquefaction plant at the Rio Grande liquefied natural gas (LNG) project. Developer NextDecade is now closer to reaching a final investment decision (FID) on the new train.

TotalEnergies joins the project with an investment of approximately US$300m and secures a 10% interest stake in Train 4. GIP's contribution is up to US$1.5bn, and the company holds 50% of the project, with a possible decrease to 30% depending on meeting return thresholds.

NextDecade itself is investing up to US$1.2bn for 40% of Train 4, with a possible increase to 60% depending on GIP's final share.

NextDecade calculates that Train 4 will have a capacity of 5.4 million metric tonnes per annum (mtpa). To be built in Brownsville, Texas, the LNG facility's construction will be carried out by Bechtel.
