Contact Congress about S. 3269: Liquid Cooling for AI Act of 2025

The bill orders a federal review of liquid cooling in AI and other high-powered data centers. It looks at cost, energy use, safety, security, and waste-heat reuse. The bill itself does not require anyone to switch cooling systems.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

Liquid Cooling for AI Act of 2025 is a Senate bill in committee. The latest recorded action: Committee on Energy and Natural Resources Subcommittee on Energy. Hearings held.

Latest action on S. 3269: Committee on Energy and Natural Resources Subcommittee on Energy. Hearings held.

Who this affects: This bill mainly affects federal agencies, data-center operators, and experts who work on cooling systems for AI and other high-powered computing. It matters most to people planning large data centers, because the study could shape future federal guidance, research money, and technology choices. It could also matter to nearby buildings or energy systems if waste-heat reuse becomes a bigger focus.

Why this matters: This matters because AI data centers use a lot of electricity and create a lot of heat, and older air-cooling systems may not keep up as computing power rises. Liquid cooling might lower energy use, support denser computing, and make better use of waste heat, but it also brings costs and technical risks. This bill tries to answer those questions before the federal government makes bigger decisions. Its long-term impact depends on whether Congress and agencies act on the study's recommendations.

Key provisions in S. 3269

• GAO must start this review within 30 days after the bill becomes law. The review focuses on liquid cooling in data centers.
• GAO must study what new research is needed, what the market looks like, and what rules affect these systems. The focus is AI and other high-performance computing facilities.
• GAO must compare the main liquid-cooling setups. That includes direct-to-chip versus immersion cooling, and single-phase versus two-phase systems, at different density levels for performance, safety, and lifetime cost.
• GAO must measure how liquid cooling changes power use and cost. That includes avoided electricity use, delayed grid and building upgrades, and more computing capacity from better cooling.
• GAO must review existing research on how liquid cooling affects speed, reliability, and cybersecurity. Cybersecurity here means how these systems could affect digital security and system protection.
