Elon Musk’s artificial intelligence company is belching smog-forming pollution into an area of South Memphis that already leads the state in emergency department visits for asthma.
None of the 35 methane gas turbines that help power xAI’s massive supercomputer is equipped with pollution controls typically required by federal rules.
The company has no Clean Air Act permits.
In just 11 months since the company arrived in Memphis, xAI has become one of Shelby County’s largest emitters of smog-producing nitrogen oxides, according to calculations by environmental groups whose data has been reviewed by POLITICO’s E&E News. The plant is in an area whose air is already considered unhealthy due to smog.
The turbines spew nitrogen oxides, also known as NOx, at an estimated rate of 1,200 to 2,000 tons a year — far more than the gas-fired power plant across the street or the oil refinery down the road. That’s according to calculations by the Southern Environmental Law Center, a nonpartisan legal advocacy group that focuses on the South, which used turbine manufacturer spec sheets to estimate xAI’s annual emissions and compare them with pollution that other South Memphis plants have reported to the Environmental Protection Agency’s National Emissions Inventory.
