Liquid Cooling for AI Act of 2025

[Congressional Bills 119th Congress] [From the U.S. Government Publishing Office] [S. 3269 Introduced in Senate (IS)] <DOC> 119th CONGRESS 1st Session S. 3269 To direct the Comptroller General of the United States to conduct a technology assessment focused on liquid cooling systems for artificial intelligence compute clusters and high-performance computing facilities, and for other purposes. _______________________________________________________________________ IN THE SENATE OF THE UNITED STATES November 20, 2025 Mr. McCormick (for himself, Mr. Coons, Mr. Budd, and Mr. Schiff) introduced the following bill; which was read twice and referred to the Committee on Energy and Natural Resources _______________________________________________________________________ A BILL To direct the Comptroller General of the United States to conduct a technology assessment focused on liquid cooling systems for artificial intelligence compute clusters and high-performance computing facilities, and for other purposes. Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, SECTION 1. SHORT TITLE AND PURPOSE. This Act may be cited as the ``Liquid Cooling for AI Act of 2025''. SEC. 2. LIQUID COOLING DEPLOYMENT AND SCALABILITY. (a) Findings.--Congress finds that-- (1) the 2024 United States Data Center Energy Usage Report published by Lawrence Berkeley National Laboratory-- (A) indicates that data centers accounted for 4.4 percent of total United States electricity consumption in 2023, up from 1.9 percent in 2018; and (B) projects that data centers could represent between 6.7 percent and 12.8 percent of total electricity consumption by 2028, due to the rapid growth of AI, cloud computing, and other digital technologies; (2) traditional air-cooled systems are reaching limits to effectively remove heat from AI chips and hardware, and liquid cooling-enhanced thermal performance is increasingly becoming a necessity for high-density AI se
