Cloud data center technology giants, including Google, Microsoft, Oracle, IBM, Tencent, Meta, and Amazon Web Services (AWS), are taking proactive steps towards renewable energy adoption, especially in the Asia-Pacific (APAC) region. A notable example is AWS constructing a secure sustainable data center for the Australian government, showcasing a commitment to green sustainability. The global sustainable data center market is on a significant growth trajectory, with investments projected to reach $85.44 billion by 2029, driven by a CAGR of 13.71% from 2023 to 2029. Companies like Vantage Data Centers, Kao Data, and Equinix are incorporating innovative fuel technologies like HVO and hydrogen to boost sustainability. For instance, in 2024, GDS China and STT GDC shifted to hydrotreated vegetable oil (HVO) and hydrogen fuel cells for backup power, marking a shift towards greener operations. Honda and Mitsubishi are pioneering a hydrogen-powered data center project in collaboration with Tokuyama Corporation, utilizing hydrogen from industrial by-products for fuel-cell power stations. Despite the higher costs and limited availability of sustainable fuels like HVO, industry players are teaming up to drive adoption, exemplified by Vantage's partnership with the Data Center Coalition for HVO support. Geographically, Nordic countries and key Western European markets like Frankfurt, London, and Amsterdam are prioritizing sustainability in data centers by leveraging renewable energy sources and advanced cooling systems. This collective effort towards green practices underscores a positive sentiment towards sustainable data center growth and environmental responsibility.
