What to know about Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use

Researchers at Washington University in St. Louis have developed a new nanostructured carbon support for fuel-cell catalysts. This innovation allows for the use of platinum-cobalt intermetallic nanoparticles that maintain stability and activity at high temperatures, potentially reducing the amount of precious metal required.

Claim 8: “The Electric Power Research Institute estimates that data centers could consume up to 9% of U.S. electricity generation annually by 2030, up from 4% of total load in 2023.”

DISPUTED

The claim attributes a 9% projection to the Electric Power Research Institute (EPRI). However, the provided evidence cites a 2025 update from Lawrence Berkeley National Laboratory estimating 11.8% by 2030. While the 2023 figure of ~4% is corroborated (4.4% in evidence), the 2030 projection and the attributing organization differ between the claim and the evidence.
