Basin to bayou: finding gas for the coming growth in the US Gulf Coast

The US Gulf Coast natural gas market faces unprecedented expansion, with demand projected to grow over 28 bcfd by 2050. This growth extends far beyond traditional LNG exports, as power generation, industrial applications, and blue hydrogen development account for upwards of 30% of expected demand increases.

Regional diversification drives market evolution

Wood Mackenzie's analysis reveals four distinct Gulf Coast sub-regions, each with unique supply and demand characteristics. West Louisiana leads LNG export buildout with direct Haynesville connectivity, whilst East Texas represents the largest sub-region where domestic demand rises alongside export growth.

East Louisiana maintains stronger ties to legacy Northeast supply sources, and South Texas benefits from continued Permian and Eagle Ford takeaway infrastructure development.

The Permian and Haynesville basins emerge as critical supply sources supporting this regional expansion, each adding around 10 bcfd to Gulf Coast supplies over the long term. Permian associated gas production, reaching peak flows above 26 bcfd to Gulf Coast demand centers in the early 2040s, provides essential supply flexibility through enhanced pipeline connectivity. Meanwhile, Haynesville non-associated production experiences accelerated growth into the mid-2030s, supporting West Louisiana's export ambitions.

Supply-demand balance shapes future infrastructure

The region's supply-demand dynamics highlight infrastructure requirements extending beyond traditional export terminals. Domestic demand growth necessitates enhanced intraregional connectivity and storage capacity. Eagle Ford production provides additional supply diversity, whilst other regional sources contribute to overall market balance.

This Gulf Coast transformation reflects broader US gas market evolution, where regional demand centres increasingly compete for supply resources. The interplay between export growth and domestic industrial expansion creates new market dynamics, requiring sophisticated supply chain management and infrastructure investment to support sustained regional development through 2050.
