Musk's push for faster gas turbines raises a pollution problem

Elon Musk confirmed on Saturday that a secret foundry SpaceX has been building in Bastrop, Texas, is meant to manufacture turbine blades and vanes — a notoriously hard-to-make part — in-house. The confirmation came hours after The Information reported on job listings referencing a “blades and vanes foundry” and findings from newsletter author Corey Trinetti that SpaceX had bought roughly 830 acres near its existing Starlink factory in Bastrop between March and June.

“The limiting factor for nat gas turbine production is casting the blades & vanes. By doing in-house casting at SpaceX, we can accelerate nat gas turbines coming online by up to 18 months, which is a profound game-changer,” Musk wrote on X.

The move targets a second AI-industry bottleneck beyond GPU shortages: the physical power grid. The International Energy Agency projects global data center electricity use will roughly double by 2030, and turbine maker GE Vernova says it’s essentially sold out of production capacity through 2030 due largely to AI infrastructure demand — pushing hyperscalers including Amazon, Google, Meta, OpenAI, and Microsoft to build private gas-fired plants next to data centers instead of waiting on the grid. Only four companies worldwide have mastered the single-crystal casting process needed to produce turbine blades at industrial scale, and all are tapped out already — a capability gap a Musk-controlled entity could close if the Bastrop foundry works.

More gas turbines coming online faster also means more pollution disputes. In Memphis, where SpaceX has run gas turbines to power its Colossus data centers since 2024, the NAACP has repeatedly accused the company of operating them without the permits or pollution controls required by federal law, citing emissions linked to asthma, respiratory disease, and certain cancers; University of Memphis researchers said in their own admittedly limited analysis that air pollution grew slightly worse because of the data center. In Virginia’s “Data Center Alley,” a Piedmont Environmental Council-commissioned study using the EPA’s COBRA model found that a single facility’s eight gas turbines could affect more than 2.5 million people across multiple counties — with the heaviest impact on already marginalized communities — and estimated 3.4 to 6.5 additional premature deaths a year, translating to $53 million to $99 million in annual health-related damages.

Why it matters

Musk’s bet on in-house turbine casting could shave months off the AI industry’s biggest physical bottleneck, but it also accelerates a build-out of gas-fired power that’s already drawing federal lawsuits and health research over its emissions.
