New heat reuse calculator supports business development of heat reuse cases

Christine Kjær Jacobsen • December 5, 2024

The Net Zero Innovation Hub has developed an online tool to estimate the value of heat provided by data centers. The tool is intended to support the business development of use cases for data center heat reuse

With nearly 100% of the electricity consumed by IT equipment dissipated as waste heat, waste heat from Europe’s data centres could make a major contribution to meeting Europe's demand for renewable heat, providing as much as 221TWh/ year or 12% of the total demand (according to EUDCA, Euroheat and Power reports).


To engage potential users, local utilities, and communities, it is useful to engage in a dialogue and be able to address a few common questions: "What is the price of heat provided by data centers? Is it competitive within the local heat market?"


To help support the business development of use cases for data center heat reuse, the Net Zero Innovation Hub has developed a basic heat reuse calculator. The tool provides an approximate cost range for the heat supplied by a data center.


The heat reuse calculator was created by the heat reuse project team at Net Zero Innovation hub.
