Sources: 7. Developments: 2. AirTrunk has initiated several strategic moves to address the infrastructure demands of artificial intelligence and cloud computing through advanced cooling technologies and large-scale capacity expansion. In September 2026, the company entered a memorandum of understanding with Australian startup Emergence Quantum to explore cryogenic cooling for data centres. This partnership aims to investigate if cooling chips to extremely low temperatures can improve performance, energy efficiency, and water conservation, while potentially enabling “giga-Watt power storage” and carbon capture applications. By October 2026, AirTrunk announced a major A$43 billion expansion in Japan to more than double its capacity to over 1 gigawatt. To facilitate this growth, the company secured a $1 billion green loan to implement liquid cooling technology at its TOK1 campus in Chiba Prefecture, specifically to manage the high heat loads produced by AI computing. ## Timeline ### 2026-10-08: AirTrunk announces A$43 billion data center expansion in Japan AirTrunk is investing approximately A$43 billion to double its data center capacity in Japan, utilizing liquid cooling technology to support the growing global demand for artificial intelligence infrastructure. 3 sources. https://clstr.news/cluster/airtrunk-announces-a43-billion-data-center-expansion-in-japan ### 2026-09-15: AirTrunk and Emergence Quantum partner on cryogenic data centre cooling AirTrunk and Emergence Quantum are partnering to explore cryogenic cooling for data centres to improve energy efficiency, reduce water usage, and support quantum computing and renewable energy storage. 4 sources. https://clstr.news/cluster/airtrunk-and-emergence-quantum-partner-on-cryogenic-data-centre-cooling --- Cite as: AirTrunk data centre technology and expansion.
