Recently, the ‘controlled nuclear fusion’ concept has gained significant momentum in financial markets, drawing widespread attention. This trend is driven by the accelerating global energy transition and growing expectations of technological breakthroughs. Controlled nuclear fusion is often hailed as the ‘holy grail’ of clean energy—it mimics the Sun’s internal reactions by fusing light atomic nuclei (such as deuterium and tritium) under extreme heat and pressure to release massive amounts of energy, with minimal radioactive waste, high safety, and abundant fuel sources.Key milestones have been achieved in recent years by projects like China’s ‘artificial sun’ EAST, the U.S. National Ignition Facility (NIF), and the international ITER program. Notably, in 2022, NIF reported the first-ever ‘net energy gain,’ where more energy was produced than consumed—a critical step toward technical feasibility. Moreover, numerous private companies are now entering the field, accelerating commercialization efforts.Market enthusiasm reflects anticipation of this long-term trend. Although commercial fusion power generation remains likely 10–20 years—or more—away, increasing policy support, R&D investment, and industrial collaboration are bolstering investor confidence. While short-term speculation should be approached cautiously, attention should focus on companies with genuine core technologies and engineering implementation capabilities.
近期，‘可控核聚变’概念在资本市场持续走强，引发广泛关注。这一现象背后，是全球能源转型加速与技术突破预期的双重驱动。可控核聚变被视为未来清洁能源的‘圣杯’，其原理是模仿太阳内部的核反应，在高温高压下将轻原子核（如氘和氚）融合，释放巨大能量，且几乎不产生放射性废料，安全性高、燃料来源丰富。近年来，包括中国‘人造太阳’EAST、美国国家点火装置（NIF）以及国际热核聚变实验堆（ITER）等项目相继取得关键进展。例如，2022年NIF首次实现‘净能量增益’，即输出能量大于输入能量，标志着技术可行性迈出重要一步。此外，多家私营企业也加入研发行列，推动商业化进程。资本市场的热情正是对这一长期趋势的提前反应。尽管目前可控核聚变距离商业化发电仍有10–20年甚至更长时间，但政策支持、科研投入加大及产业链协同效应正不断强化市场信心。投资者需理性看待短期炒作，关注真正具备核心技术与工程落地能力的企业。
