Important results from the project
The project met its planned deliverables but did not meet the goal of finding economically viable, year-round solutions. However, it provided important insights into the large impact of the cooling system, the high losses of the thermal upgrade, and the fact that MD is most compatible with the low temperatures of data centers. These results guide further POC priorities.
Expected long term effects
The project provides long‑term value by identifying which heat‑reuse technologies are unrealistic at data centers’ low temperatures and highlighting more promising options like membrane distillation. The results strengthen future POC design, guide technology choices and improve the basis for sustainable, energy‑efficient 6G edge‑node development.
Approach and implementation
Projektet drevs som en teknisk‑ekonomisk förstudie där krav och state‑of‑the‑art togs fram med partnerföretag, följt av marknadsscouting av relevanta tekniker. Konceptuella POC‑lösningar designades och systemlösningar modellerades i DWSIM för att utvärdera teknik och ekonomi. Arbetet genomfördes i nära samverkan via regelbundna möten och gemensamma analyser.
