US-based Sempra Energy has downsized its plans for the expansion of its Cameron LNG export terminal in Louisiana.
In a filing with the US Federal Energy Regulatory Commission (FERC) last week, the company proposed an expansion involving one 6.75mn tonne per year train, down from a previous expansion plan involving two trains with a combined capacity of 10mn tpy. Plans for a proposed fifth LNG storage tank would also be scrapped as a result of the amended expansion.
The two-train expansion had been approved by the FERC in 2016. However, Sempra now estimates that the regulator could approve the permit amendment by January 2023, which would allow construction to begin by April of that year.
Sempra anticipates that the proposed design changes will lower the greenhouse gas (GHG) emissions associated with the project while boosting the expansion’s reliability. It intends to replace its primary gas-driven turbines at Train 4 with e-drive compression technology, similar to what is deployed at Freeport LNG elsewhere on the US Gulf Coast.
The company estimates that this would reduce on-site emissions from Train 4 by 44% compared to the previous design. Including offsite emissions from purchased power used to run the train, Sempra estimates that its new design for Train 4 would reduce emissions by around 13% compared to its original plan.
Cameron’s three existing trains have the capacity to produce a combined 13.5mn tpy.
