AI Data Centers' Waste Heat Harnessed for Energy in Denmark, Offering Global Solution to Energy Crisis
Engineers in Denmark have developed a system to capture and reuse the vast amounts of waste heat generated by Artificial Intelligence (AI) data centers. This innovation comes as the rapid growth of AI data centers is exacerbating the global energy crisis. The International Energy Agency (IEA) reported that in 2024, data centers consumed 485 terawatt-hours of electricity, equivalent to 1.5% of the world's total energy supply, a figure projected to double to 3% by 2030, largely driven by AI development. The United Nations Economic Commission for Europe has warned that the expansion of AI hyperscalers like Google, Amazon, and Microsoft poses a significant threat to electricity systems worldwide. The new system, implemented at the Bitten supercomputer in the University of Southern Denmark, uses advanced liquid cooling technology from Danish engineering company Danfoss to pump coolant directly over high-temperature processing chips, absorbing waste heat. This heat is then channeled into Sonderborg’s municipal d...
