Senators Dave McCormick (R-PA) and Chris Coons (D-DE) introduced the Liquid Cooling for AI Act of 2025, a bipartisan bill aimed at improving the efficiency, resilience, and security of U.S. AI infrastructure. The legislation is co-sponsored by Senators Ted Budd (R-NC) and Adam Schiff (D-CA).
The bill addresses the increasing energy demands of data centers driven by artificial intelligence. According to researchers at Lawrence Berkeley National Laboratory, U.S. data centers are projected to use 580 terawatt hours of electricity by 2028, more than triple current levels and equivalent to the combined energy use of all U.S. residential lighting and household appliances.
What the Legislation Would Do
The Liquid Cooling for AI Act proposes the following actions:
- Direct the Government Accountability Office (GAO) to assess research and development needs related to liquid cooling in data centers.
- Require the U.S. Department of Energy (DOE) to evaluate GAO findings and submit recommendations to Congress on liquid cooling and heat-reuse R&D.
- Establish an industry advisory organization to assist federal agencies and develop best practices for liquid cooling technologies in AI facilities.
Liquid cooling systems are designed to support advanced chips used in AI applications and reduce the strain on utility infrastructure by improving energy efficiency.
Support From Industry and Stakeholders
The bill has support from multiple organizations and companies, including:
- AI Supply Chain Alliance
- Chemours
- UNICOM Engineering
- American Chemistry Council
- SEMI Americas
- Vertiv
- Grenzebach Group
- Accelsius
- 2CRSi
- Alcatex
- Cool Filtration
- Schneider Electric
- EneosUSA
- Modine
- University of Delaware
Supporters cite the need for more efficient cooling technologies as data centers expand and power demands increase.
Statements From Lawmakers
McCormick, Coons, Budd, and Schiff each emphasized the need to advance cooling technologies to support AI growth, reduce energy strain, maintain U.S. competitiveness, and manage consumer costs.
