The Forever Chemical Catch-22: Data Centers’ Water Worries Replace Heat Problems

The growth of data centers has long been criticized for its massive water usage, particularly in areas where water is scarce. However, a new report from ChemSec reveals that many of the world’s largest producers of “forever chemicals” are expanding their output to meet demand from AI-driven data centers.

These chemicals, known as per- and polyfluoroalkyl substances (PFAS), have become a staple in newer cooling systems due to their ability to dissipate heat more efficiently than water. However, they are notorious for their persistence in the environment and potential health risks to humans.

Major chemical producers like Daikin, Arkema, and Chemours are increasing PFAS production thanks to growing demand from the semiconductor and data center industries. In 2022, these companies pulled in around $4 billion in profit, but at what cost? The societal costs of PFAS contamination – including healthcare expenses and cleanup efforts – are estimated to be a staggering $17.5 trillion per year.

The AI boom is driving this demand as data centers require increasingly sophisticated cooling systems to mitigate the heat generated by their massive equipment. However, these chemicals pose both environmental and health risks. As of 2023, 97% of Americans have PFAS in their blood – a testament to the widespread presence of these chemicals.

Chemours, one of the largest PFAS producers, is at the center of this controversy. The company has developed products intended for data center cooling and expanded its production capacity accordingly. However, critics argue that Chemours’ application to fast-track a new PFAS chemical, Opteon 2P50, was rushed and underestimated the potential health and climate risks associated with it.

Environmental organizations have been calling for greater regulation of PFAS use in data centers, putting pressure on the EPA to take action against Chemours’ application. However, the chemical industry is known for its resistance to change, and companies like Chemours will likely fight to protect their interests.

The controversy surrounding PFAS use in data centers highlights a worrying trend: as we rush headlong into the digital age, we’re creating new problems that may be just as intractable as the ones we thought we were solving. The PFAS issue is not unique to data centers; these chemicals have been linked to contamination in food packaging, firefighting foam, and even our own bodies.

Policymakers must take a closer look at the environmental and health implications of PFAS use in data centers. We need to ask ourselves: are these chemicals truly worth the risks they pose? And what does this mean for our collective future? The answer lies not just in the numbers – but in the choices we make as a society.
