新奥聚变科学家石跃江:10年内验证氢硼聚变商业化可行性|对话能源大咖

Core Viewpoint - Controlled nuclear fusion is transitioning from concept to reality, with significant advancements in technology and increased investment in the capital market, particularly in China [1][2]. Technological Breakthroughs - The EAST device in China achieved a stable long-pulse plasma operation at 1 million degrees Celsius for 1066 seconds, marking a significant milestone in controlled nuclear fusion [1]. - The Xuanlong-50U device has successfully generated high-temperature, high-density plasma currents of 1 million amperes, a first globally [3]. - The highest electron temperature reached during experiments was 3.5 keV, equivalent to 40 million degrees Celsius, validating the potential of hydrogen-boron fusion [3]. Commercialization Prospects - The feasibility of commercializing hydrogen-boron fusion is targeted for validation by 2035, with a series of devices planned sequentially: Xuanlong-50, Xuanlong-50U, Helion-2, and Helion-3 [6]. - The Helion-2 device aims to achieve temperatures between 300 million to 500 million degrees Celsius, significantly enhancing the performance compared to previous models [6]. Challenges and Future Directions - Key challenges include achieving the necessary high temperatures of 1 billion to 2 billion degrees Celsius and maintaining stable current control [7]. - The development of the Helion-3 device will address the commercial viability of hydrogen-boron fusion, focusing on overcoming existing technical hurdles [7]. Collaborative Efforts - The company emphasizes a collaborative research environment, fostering communication across departments and seeking international partnerships to enhance experimental capabilities [8].
