Pacific Fusion已在美国新墨西哥州启动新设施建设,目标是验证聚变装置能否在设施层面实现净增益,即发出的能量至少覆盖整座设施的耗能。这被视为商业聚变发电走向落地前的一道关键门槛。

目标指向2030年

这座示范设施位于阿尔伯克基。公司计划在 2030 年前实现设施净增益,并把商业电站的运行时间指向 2030 年代中期。相比实验系统,商业级反应堆还需要输出更高能量,以支撑更多发电配套设备。

目前,聚变行业虽持续推进,但尚无装置真正跨过这一门槛。美国国家点火装置此前已证明,可控聚变反应本身能够释放出超过反应所消耗的能量,但距离覆盖整座设施总能耗仍有差距。

156个脉冲模块供能

Pacific Fusion采用脉冲电力驱动方案。其路径是用高强度、精密同步的电脉冲,在燃料靶周围形成磁场,再将约铅笔橡皮大小的燃料靶压缩至发生聚变。

公司称,示范设施每天可完成少量实验发射,而商业电站需要把频率提升到每秒一次。

  • 系统将配置 156 个脉冲模块
  • 每个模块含 32 个圆形级段
  • 每个级段由 10 个储能单元组成

公司今年早些时候测试了三分之一规模的模块样机。该样机在 80 纳秒内释放出 440 吉瓦峰值功率。Pacific Fusion表示,这一结果已足以支持示范设施进入建设阶段。

兼顾国家安全实验

除验证设施净增益外,新园区还将承接与国家安全相关的高产额聚变实验。公司技术负责人称,新示范系统单次脉冲的能量规模约为 100 兆焦耳,约为美国国家点火装置输出的 10 倍。

Pacific Fusion成立于 2023 年,是聚变赛道中较新的公司之一,但融资速度很快。该公司此前已完成超过 10 亿美元的里程碑式 A 轮融资。管理层称,这种资金安排让团队能更早规划建设节奏,减少频繁融资带来的干扰。

随着 Commonwealth Fusion Systems、Helion Energy、Proxima Fusion 和 Inertia Enterprises 等公司持续推进,聚变发电的商业化竞争正在升温。多家企业都把并网时间瞄准 2030 年代中期,部分公司希望更早实现。
