What it does

Directs the Comptroller General to initiate a review within 30 days of enactment examining liquid cooling research and development needs and market, technological, and regulatory conditions affecting data center adoption.
Requires the review to evaluate liquid cooling research needs, avoided energy costs, increased compute capacity benefits, and existing research on performance, resiliency, and cybersecurity effects.
Mandates comparison of single-phase and 2-phase direct-to-chip and immersion cooling technologies across density bands, including thermal performance, maintainability, interoperability, safety, and lifecycle cost.
Requires evaluation of coolant options, materials compatibility, corrosion control, biogrowth mitigation, filtration, fluid monitoring, heat transfer capacity, and energy efficiency.
Directs the Comptroller General and Secretary of Energy to establish an advisory committee with stakeholders from government, private sector, academia, and National Laboratories to inform the review.
