xAI has installed eight converted jet engines to power its Mississippi data center, with permits allowing a 25 percent higher pollutant limit and concerns raised over carbon monoxide.

Elon Musk's xAI is using eight converted jet engine turbines to power a data center in Mississippi. The generators have the required state-level permission and permits, but concerns remain about their potential impact on the local environment.

The permits allow a 25 percent higher limit for volatile organic compounds, a category of pollutants. Environmentalists warn that these compounds, together with the release of carbon monoxide, make the use of jet engines to power data centers a step in the wrong direction.

According to The New York Times, the Southern Environmental Law Center has already challenged Mississippi's decision to approve the turbines for use at xAI's data center.
