NextDecade Corp is to optimise its Rio Grande LNG (RGLNG) project by dropping a train.
The original front-end engineering and design (FEED) was based on six trains each capable of producing 4.5 mill tonnes per annum of LNG for export.
The technologies selected and filed with the US Federal Energy Regulatory Commission (FERC) in 2015 and 2016, have evolved over the five-year permitting period.
As a result, the LNG trains are now more efficient and will produce more LNG and lower the total carbon dioxide equivalent (CO2e) emissions.
Multiple optimisations have been identified that will lead to the delivery of an LNG project capable of producing 27 mill tonnes per year with just five LNG trains instead of six, NextDecade said.
Implementation of these initiatives will result in several environmental and community benefits when compared with the original six-train project including (i) about 21% lower CO2 emissions, (ii) shortened construction timeline for the full project, (iii) reduced facility footprint, and (iv) an expected reduction in road traffic.
“This is an extremely positive development for all of our stakeholders, as the environmental benefits from these optimisations are significant,” said Matt Schatzman, NextDecade’s Chairman and CEO. “In addition to the emissions reductions, we will achieve, these optimisations will reduce the project’s footprint, traffic, and construction schedule, and demonstrate our ongoing commitments to the community in the Rio Grande Valley.”
Any future development of Train 6 will require NextDecade to secure authorisation from FERC, the US Department of Energy, and any other relevant federal or state agency with jurisdiction over the export project, the company explained.
