谷歌为什么要收购Intersect ? 1、按照谷歌自己的说法,此次收购旨在加速谷歌数据中心容量扩张、能源开发与创新,特别是支持谷歌云和AI需求增长。同时,推动先进能源技术商 业化(如先进地热、长时储能、带碳捕获的天然气发电),利用AI优化电网连接,并提升能源效率,而不将成本转嫁给电网用户。 2、这是美国的CSP们都面临的一个问题,AI数据中心的电力需求预计到2026年将翻倍,而美国电网面临35吉瓦的电力缺口。收购Intersect允许谷歌控制 能源供应链,确保稳定供电和成本控制,而不是依赖第三方公用事业公司。这被视为AI竞争力的关键, 因为电力已成为稀缺资源,而非GPU芯片。 3、美国的政策原因:特朗普政府(包括川普、能源部长Chris Wright和商务部长Howard Lutnick等)多次公开鼓励、推动和政策支持 hyperscalers为数据 中心自建或共址发电设施(如天然气、核能或微电网),以避免过度依赖老化电网、防止电价上涨转嫁给普通居民,并加速AI基础设施建设。 4、其他CSP们在电力合作上的行动: 亚马逊通过核能主导其数据中心电力策略,与Talen Energy签署长期电力购买协议(PPA) ...
今天异常火热的液冷和昇腾链
傅里叶的猫· 2025-12-23 16:38
先说液冷。 今日液冷板块延续强势,龙头英维克在全市场超4000家下跌的悲观情绪下逆势涨停。我们认为今天 液冷板块强势除了前些日出海订单持续超预期的催化外,还与今天字节资本开支信息发酵相关,毕 竟明年起,国内液冷市场将也会呈现爆发增长。 目前国内的超节点都是液冷的形态,除了曙光是浸没式液冷,其他都是冷板式液冷。 这里再补充一点H200的事, 假如H200最终放开,那进到国内的基本都是8卡机,都是风冷的 ;包括 国内厂家的8卡机,也都是风冷为主。 大家对国内液冷市场盈利能力的担忧主要来源于与国内储能液冷市场的横向对比,认为液冷技术门 槛有限,在国内比较卷的商业环境下难有好的利润率。国内经商环境比较卷这点并否认,但储能液 冷与数据中心液冷在应用及适配门槛上差距还是比较大,从适配周期来看,数据中心液冷适配周期 显著长于储能液冷,数据中心液冷新供应商导入周期短则1年,长则2-3年,而储能液冷新供应商导 入最快速度平均在3-6个月,本质还是赛道成熟度及终端产品用途差异所致。国内数据中心液冷的毛 利,对于成本管控能力较强的液冷厂商,可以做到25%左右。 关于昇腾链,也就是国产链,我本来计划元旦前写一篇关于明年的展望时,分析 ...

Core Viewpoint - The article emphasizes that the competition in the AI data center sector is increasingly focused on electricity and energy efficiency, with North America's electricity shortage expected to be a major topic in the coming year, driving demand for gas turbines and related equipment [2]. Group 1: Industry Demand and Trends - The gas turbine industry is expected to experience sustained demand due to North America's electricity shortage, leading to upward revisions in EPS and performance growth metrics across the sector [2]. - Key potential events that could drive industry sentiment include price increases in gas turbines, performance updates from major players like Siemens Energy, GE, and Mitsubishi, and ongoing strong performance from domestic and international gas turbine supply chain companies [2][3]. - The article outlines a three-dimensional improvement in the industry characterized by increased shipment volumes, rising prices due to shortages, and improved profit margins through cost reductions and efficiency gains [3]. Group 2: HRSG Demand and Supply Dynamics - HRSG (Heat Recovery Steam Generators) are critical components in natural gas combined cycle power generation, accounting for 30-40% of the capacity of gas turbine units, and are essential for addressing the growing electricity gap in North America [4]. - The average price of HRSG units is estimated to be between $9 million and $10 million, with significant economic returns for power plants, enhancing their internal rate of return (IRR) [4]. - The supply of HRSGs to North America is constrained by various barriers, including policy restrictions that prevent the import of Chinese-made equipment, resulting in a tight supply situation [5][6][7]. Group 3: Supply Chain Challenges - The construction of HRSG production capacity overseas faces significant challenges, including the need for skilled labor, stringent regional requirements for factory approvals, and high technical standards that exceed domestic capabilities [8][9]. - The article notes that the current supply of HRSGs capable of serving North America is limited, with only a few production lines in countries like Thailand, South Korea, and Vietnam [10][11]. - A projected supply-demand gap for HRSGs in North America is expected to persist from 2026 to 2030, with an average shortfall of 20-30%, potentially reaching a peak gap of 40-50% in 2027-2028 [10][11]. Group 4: Price Expectations - Given the significant supply-demand gap, HRSG prices are expected to rise by over 20% by 2026, with prices potentially doubling by 2028 compared to 2025 levels [11]. - The article suggests that the price elasticity of HRSG products will be high due to their relatively low value contribution, indicating that prices will increase in response to supply shortages [11].
