H.R. 5332: Liquid Cooling for AI Act of 2025

The Liquid Cooling for AI Act of 2025 aims to address the increasing energy consumption and heat generation by data centers, particularly those involved in artificial intelligence (AI) and high-performance computing. The bill proposes several key actions:

1. Technology Assessment

The bill directs the Comptroller General of the United States to conduct a review focusing on the use of liquid cooling systems for data centers. This assessment will include:

• A study of the research and development needs related to liquid cooling technologies.
• An analysis of market, technological, and regulatory conditions influencing liquid cooling usage.
• An evaluation of existing liquid cooling technologies, including their effectiveness in reducing energy costs and enhancing compute capacity.
• A survey of liquid cooling adoption trends over the past five years, comparing different cooling methods.
• Recommendations on whether liquid cooling should be considered a primary option over traditional air cooling.

2. Reporting Requirements

Within 90 days of the bill's enactment, the Comptroller General is required to submit a report detailing the findings of the review, along with any recommendations. Following this, the Secretary of Energy must evaluate the report within 180 days and provide guidance to Congress about the importance of liquid cooling for maintaining the U.S.'s competitiveness in AI.

3. Stakeholder Involvement

The bill emphasizes the importance of stakeholder input in identifying best practices and industry standards for liquid cooling technologies. The Comptroller General will consult with various stakeholders, including:

• Federal, State, and local government representatives
• The private sector
• Academia
• National Laboratories

4. Advisory Organization

The Secretary of Energy and the Comptroller General will work together to designate a liquid cooling industry organization to assist with the assessment and development of recommendations. This organization will include experts in liquid cooling technology and will engage with relevant stakeholders to promote effective practices.

5. Definitions

Key definitions included in the bill clarify terms such as:

• AI: Refers to artificial intelligence as defined by relevant legislation.
• Liquid Cooling: The use of liquids to effectively remove heat from electronic components.
• Direct-to-Chip (DTC) Cooling: A method where coolant directly contacts heat-generating components to absorb heat efficiently.

6. Goals of the Bill

The overarching goal of the Liquid Cooling for AI Act of 2025 is to facilitate the adoption of advanced cooling solutions in government-operated data centers. This is expected to improve energy efficiency, enhance computer performance, and reduce costs associated with cooling technologies, thus supporting the broader deployment of AI systems across federal facilities.

Relevant Companies

• NTAP (NetApp, Inc.) - Likely to be impacted as a provider of data storage solutions which may need to adapt their systems to integrate liquid cooling technology for enhanced performance and efficiency.
• AMZN (Amazon.com, Inc.) - Amazon Web Services (AWS) is a significant player in cloud computing and may need to upgrade their data center cooling technologies to support increased AI workloads.
• NVDA (NVIDIA Corporation) - As a leader in AI and GPU technologies, NVIDIA could see implications regarding the cooling solutions required for their hardware in data centers.
• IBM (International Business Machines Corporation) - IBM's data center operations may be influenced as they look to optimize their cooling methods for high-performance computing and AI platforms.
