The US has become the world largest LNG exporter, with Gulf Coast facilities like Port Arthur, Corpus Christi, and Sabine Pass leading global supply. This guide covers the industry that transformed the global gas market.
Scale of US LNG exports
Major US LNG export terminals
| Terminal | Location | Capacity |
|---|---|---|
| Sabine Pass | Louisiana | ~30 mtpa |
| Corpus Christi | Texas | ~15 mtpa |
| Cameron LNG | Louisiana | ~15 mtpa |
| Freeport LNG | Texas | ~15 mtpa |
| Cove Point | Maryland | ~5 mtpa |
| Port Arthur LNG | Texas (under construction) | ~13 mtpa |
| Rio Grande | Texas (under construction) | ~17 mtpa |
Port Arthur LNG
Sempra Energy Port Arthur project. Two phase development. Phase 1 (13 mtpa) under construction; Phase 2 planned. Located near existing gas pipeline infrastructure. Expected commercial operations 2027.
Historical context
Until 2016, US was a net LNG importer. Shale gas revolution unlocked cheap domestic gas. Export terminals repurposed from import to export. By 2023, US became world largest LNG exporter.
Global market impact
Pricing dynamics
US LNG typically indexed to Henry Hub (US benchmark) plus liquefaction and shipping cost. Very different from historical oil indexed pricing in Asian and European markets.
How LNG export works
- Natural gas arrives at terminal via pipeline.
- Pre treatment removes impurities.
- Liquefaction cools gas to minus 162 C.
- Stored in insulated cryogenic tanks.
- Loaded onto LNG tankers at ship berth.
- Tanker delivers to import terminal.
- Regasified at import terminal into pipeline.
LNG shipping
Specialised LNG tankers (typically 174,000 to 266,000 m3 capacity). Membrane and Moss containment types. Roughly 700+ tankers in global fleet with more on order.
Pipeline buildout
US LNG export drives pipeline buildout from producing basins (Permian, Haynesville, Marcellus) to Gulf Coast liquefaction. New pipeline capacity constraints have delayed some projects.
Climate concerns
2024 pause
US Biden administration paused approvals of new LNG export permits in early 2024 for review. Trump administration lifted pause. Ongoing policy contest over LNG export scale.
Major customers
| Country | Share of US LNG imports |
|---|---|
| China | ~10 to 20% |
| Japan | ~10 to 15% |
| South Korea | ~10 to 15% |
| EU (combined) | ~40 to 50% |
| UK | ~5 to 10% |
| Rest of world | ~5 to 15% |
Jobs and economic impact
US LNG export industry supports over 250,000 jobs in construction, operations, and support. Major economic contributor to Gulf Coast communities.
Global LNG context
Qatar, Australia, and US are the three largest LNG exporters. Together supply majority of global LNG trade. Russia and Middle East (excluding Qatar) contribute significant volumes.
Where US LNG exports are going
- Continued export growth through 2030.
- Second wave of projects starting operations.
- Methane emissions requirements tightening.
- Long term contract renewals.
- Competition with Middle East and other producers.
- Climate policy contestation.
Frequently asked questions
How much LNG does US export?
~90 Bcm annually 2025. Growing to over 200 Bcm by 2030.
Where does US LNG go?
EU, Japan, Korea, China are main markets.
What is Port Arthur LNG?
Sempra project under construction in Texas.
Was US always exporter?
No. Became net exporter around 2017.
How does LNG shipping work?
Specialised cryogenic tankers.
Is LNG clean?
Cleaner than coal but not zero emissions. Methane leaks matter.
Do US LNG projects face opposition?
Yes on climate and community grounds.
What is Henry Hub pricing?
US natural gas benchmark. Indexed for many LNG contracts.
Where are terminals?
Gulf Coast primarily.
Where can I read more?
EIA, FERC, industry publications.
Summary
US LNG exports have transformed global gas markets. Major Gulf Coast terminals (Sabine Pass, Corpus Christi, Port Arthur, others) supply Europe, Asia, and beyond. Shale gas revolution made US the world largest LNG exporter. Climate concerns and policy contestation shape future direction. Global LNG trade continues expanding despite climate transition pressures.
