Technology Description:

Nokia will reuse the heat energy AI workloads produce while delivering digital services to supply high quality thermal energy that can be used directly for building heating, cooling, and/or thermal energy storage. The proposed technology will pursue a low-cost, passive, ultra-reliable, high-performance, two-phase cooling philosophy from chip to room scale. The team will rearchitect the computing infrastructure for secondary use as a valuable heat source in heat reuse applications with minimal supporting infrastructure. Available work efficiency will be maximized via heat reuse enabled by the increased flow of high-quality thermal power out of a densified server environment with corresponding energy reuse effectiveness.

Potential Impact:

Nokia will develop a highly efficient, resource-conserving, thermal energy architecture that will simultaneously improve AI server cooling energy efficiency and deliver high quality thermal energy that can be used directly for heating and cooling buildings.


This effort will contribute to ensuring that the U.S maintains a technological lead in developing and deploying advanced energy and information and communications technology.


Deploying AI in networks for building heating, cooling, and/or thermal energy storage without using additional energy would play a positive role in tackling climate change.


The new technology will enable significant cost and space savings associated with minimizing air conditioning and distribution requirements.
