What this bill does
S. 3269, the "Liquid Cooling for AI Act of 2025," would direct the Comptroller General of the United States (who leads the Government Accountability Office, GAO) to conduct a technology assessment of liquid cooling systems used to cool artificial intelligence computing clusters and high-performance computing facilities. The review would cover research and development needs, market and regulatory conditions, costs and benefits, coolant options, safety and failure risks, and comparisons among different cooling methods such as direct-to-chip and immersion cooling. GAO would consult with an advisory committee including industry, government, and academic stakeholders, and would issue a report within 90 days of enactment. The Secretary of Energy would then have 180 days to review that report and submit an assessment to Congress, including recommendations on further research and the role of liquid cooling in maintaining U.S. leadership in AI technology.
The bill primarily affects federal agencies—GAO and the Department of Energy—along with data center operators, hardware manufacturers, and researchers who may be consulted or whose practices could be studied. It does not itself regulate industry or allocate funding for cooling technology deployment; it focuses on generating information and recommendations for future policymaking.
The bill was introduced on November 20, 2025, by Senator Dave McCormick (R-PA), with co-sponsors including Senators Coons, Budd, and Schiff, and was referred to the Senate Committee on Energy and Natural Resources. It has not yet been voted on. Before becoming law, it would need committee consideration, floor votes in both chambers, and the President's signature.
