What This Bill Does

The Liquid Cooling for AI Act is a study and standards-development bill for high-density AI data centers. Congress cites rapid data center electricity growth, AI and cloud computing load, limits of traditional air cooling, and the need for interoperable liquid-cooling subsystems such as coolant distribution units, secondary loops, manifolds, hoses, quick-disconnects, pumps, leak detection, corrosion control, instrumentation, and heat-reuse interfaces. Within 30 days, GAO must begin a review of liquid-cooling research and development needs and market, technological, and regulatory conditions affecting data center use. The review must evaluate costs and benefits for high-performance computing, avoided energy and transmission costs, increased compute capacity, performance, resiliency, cybersecurity, adoption trends, direct-to-chip versus immersion cooling, coolant options, reference architectures, waste-heat reuse, and failure scenarios. GAO must consult federal, state, local, private-sector, academic, and National Laboratory stakeholders and coordinate with a liquid-cooling industry organization designated jointly with the Energy Secretary. GAO must report to DOE and congressional committees within 90 days; DOE must assess the report within 180 days and recommend research and development on liquid cooling and heat reuse.

Who Benefits and How

AI data center operators benefit from a federal review of liquid-cooling architectures, failure modes, lifecycle costs, and heat-reuse opportunities. Liquid cooling technology companies benefit from consultation with GAO, DOE, National Laboratories, and a designated industry organization. Department of Energy program offices benefit from a report focused on AI facility cooling, federal deployment decisions, and R&D priorities. Congressional energy committees benefit from GAO findings on energy costs, compute capacity, cybersecurity, and infrastructure impacts.

Who Bears the Burden and How

GAO analysts must launch the review within 30 days and report within 90 days. Energy Department staff must jointly designate an industry organization and submit an assessment within 180 days after GAO reports. Liquid cooling industry organizations must coordinate stakeholder input if designated for the review. Data center operators may face scrutiny of cooling failures, leak mitigation, cybersecurity, resilience, and market adoption.

Key Provisions

• Requires GAO to review liquid-cooling research, market, technology, and regulatory conditions for data centers.
• Requires analysis of direct-to-chip cooling, immersion cooling, coolant options, heat reuse, failure scenarios, cybersecurity, and lifecycle cost.
• Requires consultation with governments, private-sector experts, academia, National Laboratories, and a designated industry organization.
• Requires a GAO report within 90 days and a DOE assessment within 180 days after receiving the report.
