China’s Fusion Ambitions: A Growing Threat to U.S. Energy Dominance

In a stark warning to U.S. lawmakers, fusion energy expert Mumgaard has highlighted the escalating competition between the United States and China in the race for nuclear fusion technology. He asserts that China’s aggressive investments in fusion infrastructure pose a significant threat to both U.S. economic and national security. “This is a very high-stakes race worth trillions of dollars. China is positioned to win; the U.S. isn’t,” Mumgaard stated during a recent congressional session that drew limited attendance.

The Current State of U.S. Fusion Efforts

Mumgaard’s remarks underscore a troubling reality: the U.S. fusion program remains fragmented and underfunded, lacking the cohesive strategy necessary to compete effectively. He noted that while the U.S. has made some strides in fusion research, its efforts appear stagnant compared to China’s rapid advancements. “Our fusion program looks like it did a decade ago,” he lamented, emphasizing that the focus remains primarily on scientific exploration rather than practical application.

This sentiment was echoed during the Pujiang Innovation Forum in Shanghai, where Chinese officials celebrated their nation’s progress in fusion technology. Professor Zhang Jie from the Chinese Academy of Sciences revealed that China is developing a new form of inertial laser fusion at a facility in Sichuan, which is reportedly 30 times more efficient than its U.S. counterparts. If successful, this technology could produce baseload power at an astonishingly low cost of approximately $25 per megawatt-hour, potentially positioning China as a dominant force in the global energy landscape.

The Implications of China’s Advancements

Zhang, often referred to as “Dr. Fusion,” believes that the implications of this technology could be transformative, leading to an economic upheaval that surpasses the impacts of the previous three industrial revolutions: mechanical, electrical, and digital. The Chinese government was quick to recognize the significance of a breakthrough achieved by the Lawrence Livermore National Laboratory in California in December 2022, where researchers successfully generated more energy from fusion than was input into the reaction. This achievement has since been replicated multiple times, raising concerns in Washington about the potential for China to outpace the U.S. in this critical field.

Beijing’s response has been swift and strategic. According to experts, the Chinese government is mobilizing its resources to not only match but potentially exceed U.S. capabilities in fusion technology. “They are now close to operating a facility that could produce up to 10 times more yield: an enormous capability gap,” Mumgaard warned.

A New Era of Competition

China’s ambitions extend beyond just inertial laser fusion. The country is also making significant strides in traditional fusion technologies, such as those utilizing ultra-strong magnets. In January, China’s Experimental Advanced Superconducting Tokamak (EAST) achieved a record 17.7 minutes of burning plasma at temperatures exceeding 100 million degrees. This milestone has drawn comparisons to the “Sputnik moment” of the 1950s, when the Soviet Union’s space achievements shocked the United States into action.

China aims to produce its first fusion power for the grid by 2031, a timeline that has been accelerated from previous estimates. This ambitious goal, if realized, would allow China to deploy fusion plants at a pace that the U.S. may struggle to match without a concerted effort to ramp up its own fusion initiatives.

The Supply Chain Challenge

A recent study published by MIT Technology Review indicates that China currently dominates three of the six critical industries necessary for mass commercial fusion, with the potential to control two more. These industries include thin-film processing for superconducting magnetic coils and specialized metal alloys that can withstand radiation. China’s extensive experience in manufacturing, particularly in solar technology, has given it a head start in these areas.

Moreover, China’s vast network of high-speed railways and its rapid expansion of renewable microgrids have positioned it favorably in the power electronics sector. This growing dominance raises concerns about the long-term viability of U.S. energy companies, which have been slow to adapt to the changing landscape.

The Role of Private Sector Innovation

Despite the challenges, the U.S. still boasts a vibrant private sector in the fusion space. Currently, there are 53 private fusion companies worldwide, with 85% of total funding directed toward U.S. startups. Notably, Commonwealth Fusion Systems, backed by major players like Google and Nvidia, is making significant progress with plans to complete a commercial plant in Virginia by the early 2030s.

However, experts caution that without a supportive ecosystem, these private companies may struggle to achieve their ambitious goals. U.S. Energy Secretary Chris Wright has been vocal about the potential for fusion power to become a reality within the next eight years, but critics argue that the current administration is not doing enough to ensure that American companies can compete effectively against their Chinese counterparts.

The Need for International Collaboration

To bolster its position in the global fusion race, the U.S. will need to forge strategic alliances to address gaps in its supply chain. Recent agreements, such as the fusion chapter in the U.S.-UK nuclear deal, highlight the importance of international collaboration. The UK possesses significant facilities for tritium and blanket-breeding, which could be invaluable to U.S. efforts.

Mumgaard emphasized the necessity of these partnerships, stating, “The UK is the closest fit: they have facilities for tritium and blanket-breeding that are very significant, if we could get access.” However, the geopolitical landscape complicates these relationships, as nations like India and various European countries may have differing allegiances.

The Promise and Perils of Fusion Power

The advantages of fusion power are well-documented. Unlike traditional nuclear power, fusion plants cannot melt down, making them safer and easier to regulate. They produce minimal carbon emissions and long-lived radioactive waste, require less land and water, and can integrate seamlessly into existing power grids. The potential for fusion to provide a reliable, sustainable energy source is immense.

Yet, significant technical challenges remain. Researchers must find solutions to prevent neutrons from degrading reactor walls and manage unstable plasma at extreme temperatures. Despite these hurdles, the global push for commercial fusion has never been more intense.

Conclusion

As the race for fusion energy heats up, the stakes have never been higher. China’s rapid advancements in fusion technology pose a formidable challenge to U.S. energy dominance. While the U.S. has a strong foundation in private sector innovation, it must act decisively to address its shortcomings and foster international collaborations. The future of global energy may well depend on how effectively the U.S. responds to this emerging threat. The implications of a world where China leads in fusion technology could reshape the geopolitical landscape, making it imperative for Western democracies to act swiftly and strategically.
