X-energy押注亚马逊的AI电力需求，让TRISO燃料小型模块化反应堆成为现实
亚马逊气候承诺基金向X-energy投资5亿美元，押注Xe-100小型模块化反应堆加上TRISO燃料能为AI数据中心供电；该公司于2026年4月以超过10亿美元估值IPO。
X-energy
做的是什么生意
X-energy designs the 80 MWe Xe-100 high-temperature gas-cooled small modular reactor and manufactures its own TRISO pebble fuel, selling carbon-free power to industrial and data-center customers.
启动资金：$500M Series C-1 anchored by Amazon Climate Pledge Fund (Oct 2024, with Ken Griffin, NGP, University of Michigan), upsized to a $700M close (Feb 2025); $700M Series D (Nov 2025); over $1B IPO proceeds (Apr 2026).
起因
Founded in 2009 in Rockville, Maryland, X-energy spent more than a decade developing the Xe-100, an 80 MWe high-temperature gas-cooled reactor that runs on TRISO pebbles: 18,000 coated uranium particles sealed in a billiard-ball-sized graphite pebble, 200,000 pebbles per reactor, with helium carrying heat at 750°C. The founding bet was that melt-proof fuel could revive gas-cooled reactors commercially in the US.
经过
In October 2024 Amazon's Climate Pledge Fund led a $500M Series C-1 and agreed to bring over 5 GW online by 2039, starting with Energy Northwest's four-reactor Cascade project in Washington (~320 MW, expandable to 960 MW); the round closed upsized at $700M in February 2025. In May 2025 the NRC accepted the construction permit application for Dow's four-unit Seadrift, Texas plant for an 18-month review. In August 2025 X-energy signed a manufacturing partnership with KHNP and Doosan Enerbility targeting up to $50B in mobilization, and in November 2025 it began vertical construction of TX-1, the first US commercial advanced nuclear fuel facility (5 metric tons of uranium, or 700,000 pebbles a year, enough for 11 Xe-100s), while qualification testing of TRISO-X fuel started at Idaho National Laboratory.
结果
X-energy went public in April 2026, raising over $1B by selling 44.3 million shares at $23, well above the $16–19 range, after Amazon had led the 2024 round and Dow, Energy Northwest and Centrica (6 GW commitment) anchored demand. TX-1 construction was due to complete mid-2026 with NRC fuel license approval expected by May 2026; no Xe-100 reactor has generated power yet, with first electricity expected in the early 2030s.
背景
X-energy的赌注是，AI时代的电力需求将让小型模块化反应堆变得可行，而胜利者将拥有燃料。其Xe-100是80兆瓦高温气冷反应堆，使用TRISO球形燃料——每个台球大小的石墨球内含18000个包覆铀颗粒，每堆芯20万个球——其不熔毁的设计取消了传统核电站主要成本来源的安全壳。
亚马逊成了验证点。2024年10月，气候承诺基金领投5亿美元C-1轮，并承诺到2039年新增超过5吉瓦核电，首先是Energy Northwest在华盛顿州的四反应堆Cascade项目。该轮在2025年2月扩大至7亿美元；2025年5月，NRC接受了陶氏在德克萨斯州锡德里夫特的四机组工厂的建设许可申请。
2025年，X-energy构建了产业链：与韩国水电核电公司和斗山能效公司的合作旨在调动高达500亿美元资金；2025年11月，在橡树岭开始建设TX-1——美国50多年来首个商业化先进核燃料制造设施，年产70万个TRISO球形燃料，同时燃料鉴定测试在爱达荷国家实验室启动。
回报在2026年4月到来，X-energy以每股23美元IPO募资超过10亿美元，高于16至19美元的区间，亚马逊、陶氏、Energy Northwest和森特理克锚定了需求。截至2026年9月，燃料厂仍在建设中，Xe-100尚未发电；首次并网预计在2030年代初，因此最初的赌注在电网规模上仍未证实。
这件事要成立，得有什么
- TRISO燃料的不熔毁安全性直击核能最大的成本驱动因素——安全壳，而不是在反应堆物理上竞争。
- 垂直整合使X-energy成为自身反应堆的唯一燃料供应商，把技术主张变成了供应链护城河。
- 亚马逊的5吉瓦承诺在反应堆建造之前，就把资本密集型供应商变成了客户锚定的平台。
- 燃料厂里程碑（美国50多年来首个商业化先进燃料设施）在反应堆收入之前给了投资者一个硬性的、可核查的事件。
可借鉴之处
掌握燃料。X-energy把TRISO燃料制造变成了护城河，让亚马逊成为投资者，并在任何反应堆运行之前就完成了10亿美元IPO——供应链就是故事。
后续进展
截至2026年9月2日，X-energy已上市，在2026年4月的IPO中以每股23美元（4430万股）募资超过10亿美元。它报告有超过11吉瓦的新核电项目在开发：陶氏在锡德里夫特的四机组工厂正在NRC审查中，Energy Northwest的Cascade项目与亚马逊合作，以及森特理克6吉瓦的承诺。橡树岭的TX-1燃料厂预计在2026年年中完工，等待NRC许可批准，燃料鉴定测试在爱达荷国家实验室进行中。Xe-100尚未发电；首次并网预计在2030年代初。
