Antora的热电池赌注:5 GWh POET工厂上线,随后完成5.5亿美元C轮融资
Antora将廉价风能转化为碳块中的热能;其首个商用5 GWh系统在POET于2026年投运,随后完成5.5亿美元C轮融资。
Antora Energy
做的是什么生意
Antora Energy is a San Jose, California company that builds modular thermal batteries — insulated blocks of solid carbon heated with low-cost electricity — that deliver round-the-clock heat or power to industrial plants, data centers and the grid.
启动资金:$550M Series C co-led by G2 Venture Partners and Eclipse (July 2026); total corporate and project financing roughly $1B, including a $150M round in 2024
起因
Founded around 2018 by Andrew Ponec and Justin Briggs, Antora launched its first pilot in 2023: a 5 MWh system at utility Wellhead Electric's facility near Fresno, California. Months later it raised $150M and opened its San Jose factory, betting that making thermal batteries in volume — not exotic materials — would let it deploy faster than conventional storage.
经过
On May 19, 2026, POET and Antora announced commissioning of Antora's 5 GWh, multi-day thermal energy storage system at POET's Big Stone City, South Dakota biofuel plant — its first commercial-size deployment. Built in under 12 months with more than 200 factory-built modules, the system converts surplus wind power into steam for ethanol production under a long-term heat offtake agreement, and will be fully operational later in 2026; once complete it will rank among the world's largest storage projects. Grok Ventures provided project-level financing as sole external investor. Two months later Antora closed a $550M Series C co-led by G2 Venture Partners and Eclipse, with new investors including Ribbit Capital, Salesforce Ventures, Activate Capital and John Doerr, to build a second US factory and fulfill signed agreements with hyperscalers and industrial customers.
还没有结局,它还在跑。
背景
Antora Energy于2018年左右由Andrew Ponec和Justin Briggs在加利福尼亚州圣何塞创立,生产模块化热电池,将低成本电力以热能形式储存在绝热固体碳块中。其赌注是工业和数据中心将购买储存的热能,而不仅仅是电力:同一工厂制造的模块可以驱动化工厂、食品生产商、钢厂或数据中心,无需关键矿物或多年建设周期。
Antora在2023年通过弗雷斯诺5 MWh试点验证了概念,随后筹集了1.5亿美元并开设了圣何塞工厂。2026年5月19日,它达到了商业里程碑:POET和Antora宣布其位于南达科他州Big Stone City乙醇厂的5 GWh多日热能储存系统投产——这是Antora首个商业规模部署。该系统在不到12个月内建成,包含200多个模块,利用多余风能充电,并根据长期热购买协议向工厂提供蒸汽;全面运行后将成为世界上最大的储能项目之一。
该项目也是一项电价设计实验:Antora与公用事业公司Otter Tail Power共同创建了一项电价,由南达科他州公用事业委员会批准,允许系统仅在当地可再生能源过剩时充电。2026年7月,Antora完成了由G2 Venture Partners和Eclipse联合领投的5.5亿美元C轮融资(新投资者包括Ribbit Capital、Salesforce Ventures、Activate Capital和John Doerr),使公司及项目融资总额达到约10亿美元,用于建设第二家美国工厂和更多大规模项目。
这件事要成立,得有什么
- 工业过程热是一个电力尚未渗透的巨大市场,而热电池将廉价的剩余电力转化为工厂已经购买的确切形式——蒸汽——无需电网升级。
- 碳块不需要锂、钴或稀土,因此Antora的供应链和制造比电池化学初创公司扩展更快。
- 多日时长使热存储能够全天候服务于乙醇厂和数据中心,使Antora与燃气锅炉竞争,而非四小时锂离子电池。
- Otter Tail电价将间歇性的剩余风能(通常是电网的负担)转化为收入来源,为公用事业公司支持该技术提供了理由。
- POET在12个月内完成部署证明了“快速能源”的论点:模块是工厂制造的,因此项目无需等待数年建设。
可借鉴之处
销售客户已经在使用的能源形式:Antora通过提供蒸汽(而非电力)赢得了第一个客户,并将硬件与仅在电力便宜且过剩时充电的电价相结合。
后续进展
截至2026年7月30日,Antora的Big Stone City系统已向POET输送能源,预计将在2026年晚些时候全面运行,Grok Ventures提供了项目融资。5.5亿美元的C轮融资将用于第二个美国制造中心、更多大规模项目以及不断增长的超大规模数据中心和工业客户签约管道;公司表示还在开发比Big Stone大五到十倍的电力和储能项目,以加快数据中心上线。
