What does Preamble of Liquid Cooling for AI Act of 2025 do?

This bill directs 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. The bill requires the development of Federal Government-wide best-practice guidance for Federal agencies. The bill has other purposes not explicitly detailed in this section.

What does SHORT TITLE AND PURPOSE. of Liquid Cooling for AI Act of 2025 do?

This Act is formally titled the Liquid Cooling for AI Act of 2025.

What does FINDINGS. of Liquid Cooling for AI Act of 2025 do?

This section outlines findings related to data center energy usage and cooling technologies. Data center electricity consumption has increased significantly, reaching 4.4% of total U.S. consumption in 2023 and projected to rise to 6.7-12.8% by 2028 due to AI and cloud computing. Traditional air-cooled systems are becoming less effective for high-density AI servers, necessitating liquid cooling solutions. Liquid-cooling technologies like direct-to-chip and immersion cooling can improve performance and reduce cooling system load. Effective liquid cooling requires interoperable components and engineered subsystems. Heat reuse interfaces are important for reducing thermal load. Federal agencies are considering deploying AI systems in government facilities. A comprehensive assessment of data center architectures and cooling technologies is deemed essential for informed deployment decisions within the Federal Government.

What does LIQUID COOLING DEPLOYMENT AND SCALABILITY. of Liquid Cooling for AI Act of 2025 do?

This section requires a review by the Comptroller General of the United States of liquid cooling utilization by data centers, including research and development needs and related market, technological, and regulatory conditions. The review must include an evaluation of liquid cooling research and development needs, a description of avoided costs of energy, and an assessment of market trends. The review will also compare direct-to-chip (DTC) liquid cooling and immersion cooling approaches and evaluate coolant options. The Comptroller General must include recommendations for the Federal Government’s utilization of liquid cooling technologies and best practices for design and operation. Stakeholder input, including from Federal, State, and local governments, the private sector, academia, and National Laboratories, is required. A liquid cooling industry organization will be designated to consult and coordinate in the preparation of the review. The Comptroller General must submit a written report of the review’s results and recommendations to the Secretary of Energy and Congress within 90 days of enactment. The Secretary of Energy must then evaluate the report and submit an assessment, including considerations for Congress regarding liquid cooling’s importance for maintaining U.S. leadership in AI technologies.
