猛砸120亿，搞人造太阳：这赛道，蚂蚁刚刚进场

Group 1 - Significant capital investment has been made in controllable nuclear fusion companies, with over 12 billion yuan raised in 2023 alone [1][2][10]. - The concept of controllable nuclear fusion involves creating a "mini-sun" on Earth, which could provide a sustainable energy source, addressing the limitations of fossil fuels and intermittent renewable energy sources [1][2][4]. - The technology is still in its early stages, with major projects like ITER expected to take years before commercial viability is achieved, yet there are already companies generating revenue in related sectors [5][17][20]. Group 2 - Key advancements in nuclear fusion technology include the successful ignition at the NIF in December 2022, the development of high-temperature superconducting magnets, and the application of AI for plasma stability [8][9][10]. - A variety of companies are emerging in the nuclear fusion space, with over 30 financing events reported in China since 2024, indicating a growing interest and competition in the sector [12][14]. - Companies are focusing on different aspects of nuclear fusion, including device construction, new materials, and commercial applications, with significant investments from both domestic and international players [13][20][23]. Group 3 - The nuclear fusion industry is at a critical juncture, with both government and private sectors recognizing the need to invest in future energy solutions [14][21]. - Companies are categorized into three segments: upstream (new technology development), midstream (integration and assembly of core devices), and downstream (commercial energy output) [24][26]. - The timeline for commercial nuclear fusion energy production is projected to be within the next 15 years, with expectations for operational "mini-suns" to contribute to energy supply [27].
