Summary of Key Points
Recently, CATL, the global leader in power batteries, made its first cross-industry investment into the field of nuclear fusion, leading a seed round of several hundred million yuan in Beta Fusion, which was established just six months ago. This move attracted more than fifty institutions to compete for investment opportunities. The sudden interest in nuclear fusion is driven by several factors: the urgent need for stable and clean electricity in scenarios such as AI data centers, policy support, and a technological breakthrough. Nuclear fusion, once mocked as having "another fifty years to go," has now become a highly sought-after target for investors.
In this race, state-owned entities are pursuing the more conservative Tokamak approach, while private companies are betting on the more aggressive FRC (Fast Reactor Configuration) route. Energy giants, internet companies, and automakers are all entering the market, despite the high risks, as no one wants to miss out on the potential of future energy technologies.
Why Is CATL Entering the Nuclear Fusion Field? — From Storing Electricity to Generating It
CATL's traditional business focused on how to store electricity—producing batteries, energy storage systems, and battery swapping services. Now, it aims to address the question of where electricity comes from. This shift was not made on a whim; CATL's founder, Zeng Yuqun, has long stated that the company intends to become a "green energy provider" by 2024 and predicted that the market for zero-carbon grids could be ten times larger than that for electric vehicle batteries.
Why take this risk? Firstly, CATL has the financial means; its revenue in the first quarter of 2026 reached 129.1 billion yuan, a year-on-year increase of 52%. Secondly, it has experience: from being an underdog company in 2011 to becoming the global leader through strategic investments (such as in power batteries). By investing in Beta Fusion, CATL aims to integrate nuclear fusion into its zero-carbon energy ecosystem, transforming itself from a battery manufacturer to an energy service provider.
The FRC Route Chosen by Beta Fusion: A Short Cut or a Risky Path?
There are two main approaches to nuclear fusion:
- Tokamak: This is the route followed by well-known projects like EAST (China's "Artificial Sun") and the international ITER. Its advantage is stable, long-duration operation, but it requires large facilities, high costs, and slow progress in development.
- FRC (Fast Reactor Configuration): Beta Fusion has chosen this approach, which uses millisecond pulses to increase plasma density instantly, focusing on short-term efficiency rather than long-term stability. The benefits include smaller facilities, lower costs, and faster innovation, making it suitable for distributed applications like data centers and remote islands that do not require large power plants.
However, FRC is considered the most aggressive and risky route. No third-party has yet confirmed its Q value (the ratio of output energy to input energy, which must be greater than 1 for profitability), and the entire power generation process has not been fully validated. Nevertheless, American company Helion Energy has given confidence by tripling its valuation in just one year and signing a power supply agreement with Microsoft. This similarity in approach is one reason CATL decided to invest.
How Competitive Is the Nuclear Fusion Field? — State-Owned and Private Entities Going Their Own Ways
The nuclear fusion field is divided into two camps:
- State-Owned Entities (Conservative): Focusing on the Tokamak route, such as the China Fusion Energy Company established in 2025 with a registered capital of 15 billion yuan, involving state-owned enterprises like CNNC and CNPC.
- Private Entities (Aggressive): Betting on FRC, including companies like Hefei Aggregation Fusion (which received several hundred million yuan in angel funding), Shanghai Nova Fusion (raising 1.2 billion yuan in a year with investments from Alibaba and Meituan), and Chengdu Hanhai Jueneng (the first domestic company using the FRC technology).
Investors come from a wide range of sectors:
- Energy Giants: CATL, CNNC, CNPC
- Internet Companies: Alibaba (invested in Nova Fusion), Baidu (in Aggregation Fusion), Ant Group (in Xingneng Xuanguang)
- Automakers: NIO (in Energy Singularity), Ford (in Helion Energy)
- Generalists: Sequoia Capital, Hillhouse Capital, Zhongke Chuangxing (investing in both routes, betting on the entire field rather than just one)
The Surprising Popularity of Nuclear Fusion
There are three main reasons for the sudden interest in nuclear fusion:
1. The Demand from AI: Large AI models and data centers consume massive amounts of electricity that require stable, clean power 24/7. Microsoft's power supply agreement with Helion is a prime example of this trend.
2. Policy Support: The 2025 Atomic Energy Law includes nuclear fusion for the first time, and the "14th Five-Year Plan" lists it as a future industry. The 2026 plan links computing power with electricity supply, providing confidence to investors.
3. Technological Breakthroughs: China's Huanliu-3 reactor achieved a significant performance milestone, marking a shift from research to practical applications. Global investment in nuclear fusion has surged, with total funding increasing from 1.9 billion yuan to 9.7 billion yuan over the past five years and the number of companies doubling.
The Cold Reality Behind the Hype: Significant Risks
Despite the excitement, many challenges remain:
- Unverified Technology: The Q value for FRC has not been confirmed by third parties, and the stability of the technology is uncertain.
- High Costs: Early-stage nuclear fusion power will likely be expensive; will there be enough demand to justify the costs?
- Long Development Time: It may take more than a decade to move from prototype development to commercial power generation.
Even investors are cautious. Chinese companies like CNNC and Zhejiang Energy Power have stated in their announcements that controlled nuclear fusion is still in its developmental stage and may not be profitable in the short term.
However, the focus on electricity as a core technology for the future—whether for AI, smart cities, or electric vehicles—is driving this investment. If nuclear fusion becomes viable, it could become the ultimate energy source. Getting involved now, even if the chosen route turns out to be wrong, is better than waiting until the endgame.
The old saying "another fifty years" is being challenged by the immediate need for electricity driven by AI. The goal may still be far off, but investors are eager to take action.
