Elon Musk’s AI company, xAI, has received a permit to operate natural gas-burning turbines at its supercomputer facility in Memphis, Tennessee.

The Shelby County Health Department issued the permit on July 2, 2025.

The permit allows xAI to run 15 turbines at the site, subject to specific emissions limits and testing requirements.

Non-compliance may result in daily fines of up to US$10,000 per violation.

This decision followed months of protests and public hearings.

During this time, local residents expressed concerns about air quality issues linked to the turbines.

🧠 Food for thought

1️⃣ Nitrogen dioxide emissions carry significant health risks, especially in concentrated areas

The health concerns of Memphis residents about xAI’s natural gas turbines are supported by substantial scientific evidence about nitrogen dioxide (NO2) emissions.

Air pollution causes approximately 6.7 million premature deaths annually worldwide, with NO2 being a significant contributor to respiratory and cardiovascular diseases 1.

Studies show that exposure to nitrogen dioxide, primarily produced during high-temperature combustion like in natural gas turbines, can cause immediate respiratory issues in the short term and contribute to chronic respiratory diseases with long-term exposure 2.

The EPA’s air quality reports indicate that while nationwide emissions of nitrogen oxides have decreased significantly over the past decades, localized emission sources like power plants can still create hotspots with elevated pollution levels 3.

2️⃣ AI data centers face growing scrutiny over massive energy requirements

xAI’s installation of 200,000 GPUs at its Memphis facility highlights the enormous energy demands of modern AI infrastructure 4.
