China is experiencing a different kind of nuclear race as everyone from government labs to private sector giants and startups seek to develop next-generation fusion energy.
It comes as the nation’s broader nuclear sector grows, with an installed capacity of 57 gigawatts (GW) by the end of 2023, according to the China Nuclear Energy Association. The country’s 55 operating nuclear reactors — which use conventional fission technology — contributed 4.86% of total power generation last year, the association’s data show, and that figure is expected to rise to 10% by 2035.
Fusion is a different beast. Unlike mature fission approaches, which echo an atom bomb, the process of fusing atomic particles to provide energy promises to be safer and less polluting. But its development is still in its infancy.
Chinese engineers and businesspeople working in the fusion space are now tapping private capital in China and the U.S. as they buckle down for the years — or decades — of research it could take to turn it into a viable electricity source.
A cream-colored plant in the north of Xi’an houses one such hopeful developed by Chinese startup Shaanxi Startorus Fusion Technology Co. Ltd. The “tokamak,” a sort of artificial sun inside a donut-shaped magnetic bottle, is one type of fusion reactor.
This year the company hopes to use magnetic superconductors to elevate the interior temperature of the device to a staggering 17 million degrees Celsius — hot enough to fuse atomic nuclei and unleash a massive burst of energy.
The startup, founded more than two years ago, hopes rather optimistically to bring the device to market by around 2032. But it will need to solve many elusive problems of nuclear physics before it does.
The startup world rarely sees decade-long development pipelines outside of the pharmaceutical industry. But the stakes are high. Nuclear fusion, the physical process which powers stars like our sun, holds promise as a future source of relatively clean and affordable energy.
It can potentially produce four times more energy per kilogram of fuel than fission and almost 4 million times more than burning oil or coal, according to the International Atomic Energy Agency, an intergovernmental body under the U.N. which promotes the peaceful use of nuclear energy.
An infant technology
Scientists have been experimenting with nuclear fusion for around a century. But they only achieved a fusion reaction that produced more energy than was fired into it for the first time in December 2022 at the Lawrence Livermore National Laboratory in California.
Experts cautiously hailed the feat — known in the field as “ignition” — but said the experiment had resulted in a net loss of energy when factoring in the power used to charge the laser. One professor pointed out the energy produced was only enough to boil a kettle.
Commercialization of such technology could be decades away given the complex issues left to solve. “To go from [that experiment] to a commercial nuclear fusion reactor could take at least 25 years,” said Mark Diesendorf, a physicist who researches sustainable and nuclear energy at the University of New South Wales in Australia, at the time. “By then, the whole world could be powered by safe and clean renewable energy, primarily solar and wind.”
But in China, many appear undaunted. “Realizing controlled nuclear fusion will change the global energy landscape. The dominance in the energy market will shift from countries that control resources to those that control the technology,” said Jin Zhijian, director of the High-Temperature Superconducting Materials and Systems Research Center in Shanghai.
China’s ambitious dual climate goals announced by President Xi Jinping in September 2020 have buoyed the field. The nation is the world’s largest energy importer and biggest burner of coal — the most polluting fuel source in terms of the carbon emissions that cause climate change. Fusion was even namechecked in the National Development and Reform Commission’s annual work report to the National People’s Congress, delivered last month as part of the “Two Sessions” in Beijing.
The money is starting to follow.
Funding mushrooms
Global investment in fusion technology hit $6.2 billion in mid-2023, up 31% from mid-2022, according to a report by the Fusion Industry Association, an international lobby group pushing the commercialization of fusion. More than 95% of that came from the private sector, it said.
The number of startups in the field increased to 43 in the first half of 2023 from 33 in 2022, the report said. Twenty-five of those startups told the association they think the world’s first fusion plant will be hooked up to a grid between 2025 and 2035.
Chinese companies of all shades — from startups and listed firms to government-backed enterprises — are exploring the field.
Startorus Fusion closed a 2 billion yuan ($281.6 million) angel round in June 2022. Twelve institutional investors, including venture capital (VC) giant HongShan, committed funding. Seven months later the company installed its Xi’an reactor, which fired for the first time in July. The firm announced on March 27 it had closed a multi-million yuan Pre-A round of funding.
Founded in October 2021 by CEO Chen Rui, Startorus Fusion comprises a team of nuclear physicists from Tsinghua University, one of China’s most competitive science institutions. Yet, Chen told Caixin that national research funding alone was not sufficient to develop nuclear fusion technology.
“Europe and the United States have begun to commercialize [this technology], and if we don't do it, we may not have a chance to compete,” Chen said.
Energy Singularity, another nuclear fusion startup, concluded a nearly 400-million-yuan angel round in February 2022. The investment was led by MiHoYo and Nio Capital, with participation from HongShan and Lanchi Ventures. The company closed another nearly 400-million-yuan Pre-A funding round in April 2023, again with MiHoYo joining.
MiHoYo is the developer of the hit action mobile game Genshin Impact, and Nio Capital is an investment firm founded by William Li, CEO of Chinese electric-vehicle maker Nio Inc.
Ye Yuming, the chief operating officer of Energy Singularity, said he noticed a growing number of fusion startups in the U.S. drawing backing from mainstream institutional investors since 2021, which he said signaled potential.
Large private firms are also exploring the field. Chinese gas giant ENN Group fired its nuclear fusion device Xuanlong-50U for the first time on Jan. 24 this year. The group has been exploring nuclear fusion devices since 2018.
Public-private links
State-supported research institutions and enterprises are often behind the tech. In May 2023, Neo Fusion was established in Hefei, Anhui province, with a registered capital of 5 billion yuan. Shareholders include Nio Capital and state-backed Anhui Province Energy Co. Ltd. It plans to build a nuclear fusion device called BEST.
The chairman and general manager of Neo Fusion is Yang Xiaofeng, a former manager at China General Nuclear Power Corp.’s technology department with about 40 years of experience in nuclear fission.
One of the company’s technology backer, the Institute of Plasma Physics under the Chinese Academy of Sciences (CAS) in Hefei, has been researching in the field of fusion for around the same time. In April 2023, its Experimental Advanced Superconducting Tokamak (EAST) set a world record for generating and holding plasma — a hot, ionized gas consisting of nuclear fuel — when it ran for 403 seconds, a key step for the team to develop a fusion demonstration reactor.
This approach, known as magnetic confinement fusion, is also used by Startorus. It represents an alternative fusion path from the laser fusion approach used at Livermore.
China National Nuclear Corp. (CNNC) has also begun to make plans. In November, CNNC signed a strategic cooperation agreement with the Jiangxi government, planning to start a nuclear fusion project in the province with expected investment of more than 20 billion yuan.
On Dec. 29, led by CNNC, 25 state-owned enterprises, scientific research institutes and universities announced they were establishing a nuclear fusion innovation consortium in Sichuan province.
Upstream surge
Magnetic confinement fusion, in which hydrogen plasma is heated and squeezed in a magnetic bottle, requires the use of magnetic superconductors with little resistance that can withstand high pressures and temperatures.
Superconducting magnets could account for 40-50% of the cost of these devices, said Jin of the High-Temperature Superconducting Materials and Systems Research Center. Superconducting magnets are to fusion reactors as batteries are to electric vehicles, he said.
In June 2022, Jin founded superconductor startup Shanghai Yixi Technology Development Co. Ltd., which took in 50 million yuan in seed funding led by CAS Star.
“Controlled nuclear fusion will raise the consumption of superconducting strips by two times,” Jin predicted. He believes scale will bring down the costs.
In June 2023, Shenci Technology, another startup focusing on superconducting materials, secured angel round financing from CAS Star, which also staked Startorus.
The founding partner of CAS Star, Mi Lei, said superconducting materials are a significant upstream investment opportunity.
In October 2023, Shenci Technology received funding from Lenovo Capital & Incubator Group and China Aerospace Investment Holdings Ltd., the investment arm of China Aerospace Science and Technology Corp.
Shanghai Superconductor Technology Co. Ltd., a Chinese manufacturer of the materials, is preparing for an uptick in demand, with the company’s chief engineer Zhu Jiamin telling a conference in November that the firm plans to accelerate production of the superconductive strips.
Miles to go
A number of investors who spoke to Caixin compared the development of nuclear fusion to the private satellite industry, which emerged on the back of the commercialization of nationally-funded research.
The difference, says Yang Runxin, vice president of VC firm K2VC, is that firms like Elon Musk’s Space X entered a mature rocket industry with an established commercial model and large-scale operations, whereas nuclear fusion technology is in its infancy. Nobody knows whether pathways like laser-fusion, magnetic confinement fusion and others, with all their various approaches, will ultimately prove a winning formula.
Wang Guangxi, a partner at Lenovo Capital, emphasizes the high costs associated with nuclear fusion due to the extremes of physics involved. The continuous need for exploration and improvement further escalates funding requirements in later stages. Addressing the various challenges across the industry supply chain is crucial, and uncertainties extend to how governments will regulate the field, potentially influencing whether national dominance will be a requirement.
In its report, the Fusion Industry Association warns that, amid a worsening global financing environment, venture capital has tended to limit funding to seed and Series A rounds for fusion startups, which could see them perish in the “valley of death” — where companies struggle to find the continued funding that allows them to scale up projects.
That means, with paths to market that could last decades, the only thing many fusion hopefuls may end up burning is cash.
