Liquid Cooling for AI Act of 2025

This bill directs the Comptroller General of the United States to conduct a technology assessment on liquid cooling systems for AI compute clusters and high-performance computing facilities, and requires the Secretary of Energy to review the findings and submit recommendations to Congress.

Sec. 2, Liquid cooling deployment and scalability: The bill requires the Comptroller General to start a review within 30 days of enactment on research and development needs for liquid cooling in data centers and related market, technological, and regulatory conditions. The review must include evaluations of costs and benefits, avoided energy costs, increased compute capacity, effects on performance and cybersecurity, market trends, comparisons of cooling methods, coolant options, failure scenarios, and recommendations on whether liquid cooling should be a primary option, federal research, best practices, and security methods. The Comptroller General must consult stakeholders and establish an advisory committee with experts from industry, hardware manufacturers, data center operators, and fluid producers. A report must be submitted to the Secretary of Energy and Congress within 90 days. The Secretary of Energy must then submit an assessment and recommendations to Congress within 180 days, including considerations for U.S. leadership in AI and research on liquid cooling and heat-reuse.
