Honeywell to supply liquefaction technology for Rio Grande LNG Trains 4–5

13 April 2026

Key highlights

NextDecade's Rio Grande LNG will use Honeywell CWHE equipment and C3MR liquefaction technology for trains 1-5, supplied via EPC contractor Bechtel.
Adding Trains 4 and 5 increases LNG capacity from 18 MTPA to 30 MTPA, a >66% rise.
All five trains are expected to be operational by mid-2031.

Project scope

Honeywell's C3MR liquefaction process and coil wound heat exchanger (CWHE) equipment will be supplied for NextDecade's Rio Grande LNG Trains 4 and 5 in Brownsville, Texas, under an agreement with EPC contractor Bechtel; the same Honeywell technology is also being used on the project's first three trains.

Technical scope

NextDecade will use CWHE and C3MR to optimize production, improve reliability and reduce facility operating expenses; the article also notes Honeywell offers pretreatment and liquefaction technologies, automation and software, modular off‑site construction options, CWHE units with compact footprint and high throughput, and that C3MR is the most‑utilized liquefaction process globally per the 2025 IGU report.

Capacity and schedule

Adding Trains 4 and 5 raises Rio Grande LNG capacity from 18 MTPA to 30 MTPA (more than a 66% increase), and all five trains are expected to be operational by mid‑2031.
