SpaceX is developing an in-house foundry to manufacture critical gas-turbine components, potentially helping AI data centres secure power faster while increasing concerns over emissions and public health.

Elon Musk is betting that manufacturing critical gas-turbine components in-house could help overcome one of the biggest obstacles facing the artificial intelligence industry: access to electricity.

Musk recently confirmed that SpaceX is developing a secret foundry in Bastrop, Texas, alongside plans to rapidly expand solar manufacturing capacity. He said natural gas would still be required to supplement solar power for several years and argued that producing turbine blades and vanes internally could accelerate the deployment of gas turbines by as much as 18 months.

The strategy comes as technology companies race to build increasingly power-hungry AI data centres. While shortages of advanced chips have dominated the AI industry's supply concerns, electricity availability is emerging as another major constraint.

AI Data Centres Need More Power

The rapid expansion of generative AI and high-performance computing is driving unprecedented demand for electricity.

The International Energy Agency expects data-centre electricity consumption to double by 2030, putting additional pressure on power grids and generation capacity.

Technology companies are therefore exploring ways to secure dedicated electricity supplies instead of waiting for conventional grid connections, which can take years in some parts of the United States.

Companies including Amazon, Google, Meta, OpenAI and Microsoft have explored or pursued arrangements involving gas-fired generation near data-centre sites.

The approach provides a potentially faster route to reliable power, particularly in regions where grid infrastructure is struggling to keep pace with new demand.

Musk Plans In-House Foundry

Musk said SpaceX is building its own manufacturing capability for the most difficult components used in gas turbines.

“The limiting factor for nat gas turbine production is casting the blades & vanes,” Musk wrote on X. He said in-house casting at SpaceX could accelerate gas-turbine deployment by up to 18 months.

The plan is linked to Musk's broader energy strategy, which includes a target of developing 100 gigawatts of annual solar production capacity as quickly as possible.

Natural gas would serve as a supplementary source while solar capacity expands, according to Musk.

If successful, the approach could give SpaceX and its associated AI operations greater control over power infrastructure and reduce dependence on specialised turbine suppliers.

Turbine Parts Are Difficult

Gas-turbine blades and vanes are among the most technically demanding components in modern power generation.

The parts operating in the hottest sections of turbines can face temperatures of roughly 3,000 to 3,600 degrees Fahrenheit. That is hundreds of degrees higher than the melting point of the metal alloys used to manufacture them.

Engineers rely on advanced alloys, thermal-barrier coatings and internal cooling channels to prevent the components from failing under extreme operating conditions.

The manufacturing process is equally challenging.

Single-Crystal Casting Challenge

Turbine blades used in the hottest sections often require single-crystal structures, meaning the component is produced without grain boundaries that could become weak points under extreme temperatures.

The casting process requires carefully controlling the growth of the crystal inside a vacuum furnace.

Even tiny imperfections can create weaknesses that may eventually cause cracks during operation.

While specialised manufacturers already produce these components at industrial scale, the rapid growth in demand for gas-fired generation has placed additional pressure on available production capacity.

Turbine Supply Limits AI

GE Vernova has indicated that its gas-turbine production capacity is effectively sold out through 2030, highlighting the scale of the supply constraint.

For AI companies, the shortage creates a problem beyond simply finding fuel. Even when natural gas is readily available, companies may struggle to obtain turbines capable of converting it into electricity quickly enough.

Musk's proposed solution is to remove one of those bottlenecks by bringing component production inside SpaceX.

If the company can manufacture turbine blades and vanes more quickly, it could potentially shorten the timeline for installing new generation capacity.

Gas Power Raises Pollution Risks

The strategy also creates an environmental trade-off.

Natural-gas turbines can provide reliable electricity and are generally less carbon-intensive than coal-fired generation. However, gas combustion still produces carbon dioxide and air pollutants, including nitrogen oxides.

The rapid construction of gas plants near AI data centres could therefore increase emissions in areas already facing pressure from industrial development.

Local communities may also have concerns about air quality, noise, water use and other environmental impacts associated with large power facilities.

AI Power Race Intensifies

The push for dedicated gas generation illustrates how the AI boom is increasingly becoming an energy-infrastructure race.

Technology companies need enormous quantities of reliable electricity to operate data centres filled with advanced computing hardware. Grid expansion, transmission projects and generation facilities can take years to develop.

Musk's strategy attempts to address that problem by combining faster turbine manufacturing with a long-term expansion of solar capacity.

However, the success of the approach will depend on whether SpaceX can overcome the demanding engineering requirements of turbine-component production at scale.

Power Boost Comes With Cost

If Musk's manufacturing plan succeeds, it could help bring additional gas-fired electricity online faster and potentially give SpaceX an advantage as competition for power intensifies.

But accelerating gas-turbine deployment could also deepen the technology industry's reliance on fossil-fuel generation at a time when governments and companies are under pressure to reduce emissions.

The longer-term challenge will be balancing the enormous electricity requirements of AI with the need for cleaner energy sources.

For Musk, the immediate strategy appears to be a combination of solar expansion and natural-gas backup. Whether that becomes a temporary bridge or a significant part of the AI power system will depend on how quickly renewable generation, grid infrastructure and energy-storage technologies can scale.
