2025年全球数据中心展望：塑造明日数字基础设施

Core Insights - The global data center industry is projected to grow at a compound annual growth rate (CAGR) of 15% through 2027, potentially reaching a CAGR of 20% by that year, driven by ongoing construction and planned developments [3][4] - The industry faces both opportunities and challenges, including the emergence of new technologies for sustainable growth and value creation, as well as power constraints and demand surges exceeding supply [3][4] Group 1: Artificial Intelligence (AI) - AI applications are expanding across nearly all industries, with significant investments made in recent years, indicating continued growth in demand for AI data centers by 2025 [4][10] - The rapid advancement of semiconductor technology is driving the AI revolution, with GPU density expected to increase significantly, leading to higher power consumption in data centers [11][15] - AI training facilities require substantial energy, often exceeding 1 GW, necessitating a separation from inference facilities to optimize power usage and reduce latency [18] Group 2: Power Grid - By 2025, global electricity demand is expected to grow by approximately 4%, with data centers accounting for only about 2% of this increase, highlighting the need for a comprehensive approach to address global electricity challenges [23][24] - Data center clusters are causing power transmission bottlenecks, delaying development in major markets and shifting investments to new areas [26][31] - The energy consumption of data centers is projected to double in the next five years, reaching 100 GW, driven by the increasing demand for computing power [27][28] Group 3: Liquid Cooling - The shift towards liquid cooling technology is becoming essential for managing the increasing power density in data centers, with liquid cooling now constituting 70% of new installations [54][55] - Immersion cooling is anticipated to become more common as GPU power requirements exceed 150 kW, although widespread adoption will take several years [57][58] - The industry is facing challenges related to the quality and reliability of cooling liquids, as well as structural design considerations for immersion cooling systems [57][58] Group 4: Capital Markets - Investor confidence in data centers remains strong, with 2025 expected to be another record year for development financing, driven by the exponential demand for computing power and data storage [63][64] - Approximately $170 billion in asset value will require financing in 2025, with about 10 GW of new large-scale and colocation data centers expected to begin construction [65][66] - M&A activity in the data center sector may slow down as the industry matures, with a shift towards joint ventures in emerging markets [70][71]
