Data4, a European data center operator, is embarking on an innovative project to repurpose server-generated heat and captured carbon dioxide to cultivate algae. This algae can be utilized within the agri-food and pharmaceutical sectors. Currently, a proof-of-concept setup is operational in Paris, boasting an absorption capability 20 times greater than that of trees.

Data4 plans to expand this initiative by installing algae modules on building facades, aiming to produce 20 kg of algae and capture 36 kg of CO2 daily. Collaborating with the University of Paris-Saclay, Blue Planet Ecosystems, and local authorities, this project seeks functional and economic sustainability. While various heat reuse strategies were explored, repurposing it for algal growth emerged as a promising solution.

Data4’s innovation head Linda Lescuyer emphasizes that the heat recovery strategy could transform currently unused energy into a new regional resource, potentially generating jobs and ushering in ecological and economic benefits.

This push towards greener operations is part of a broader industry response to increasing environmental regulations and the growing demand for sustainable practices, especially with the expanding AI sector impacting energy consumption. Data4 hopes to replicate this model across Europe if pilot phases yield success, and is in discussions with potential partners from related industries for future collaborations.
