Top 20 Green Energy startups in China
1
Hanhai Energy is developing FRC nuclear fusion reactor HHMAX-901 that costs only about 200 million RMB to build, far lower than the tokamak unit. More importantly, key components of the device can be reused into the next generation, meaning we can iterate engineering faster and adapt to technological innovation. The startup backed is by top national research teams such as the Southwest Institute of Physics and the China Academy of Engineering Physics, and leveraging China’s systematic industrial support for precision processing and high-end devices

Energy Singularity is developing the HH70 tokamak, which utilizes high-temperature superconductors and has already set a world record for commercial fusion devices by maintaining a stable plasma current in long-pulse mode for 1,337 seconds. According to the company, this achievement was made possible through the continuous optimization of an AI-based plasma control system. The company aims to reduce the levelized cost of electricity generated by fusion plants to a level comparable to, or even lower than, that of thermal power plants.

NovaFusionX is developing small modular fusion reactors using a field-reversed configuration (FRC) approach. By using magnetic compression technology to increase the density and break through the threshold of fusion conditions, the system does not need to rely on ultra-high-power lasers. At the same time, through modular design, it effectively avoids a series of key technical challenges faced by tokamak reactors. Thus (according to the startup) the construction cost and R&D cycle of the nuclear fusion power plant can achieve double significant breakthroughs, and it is expected to enter the commercialization stage earlier in a shorter time.

Startorus Fusion is a commercial nuclear fusion company, building spherical tokamak device SUNIST-2 in collaboration with Tsinghua University. The spherical tokamak, as a compact tokamak device, is more economical in terms of funding and space utilization. Due to its design, it has a higher ratio of plasma pressure to magnetic field pressure. The company already completed its first operational run, achieving a plasma current of 100 kiloamperes. It is the strongest magnetic field and highest-performance spherical tokamak in China. The startup is targeting technical verification by 2028 and pilot plant by 2032.

SunUp Fusion is constructing its first-generation experimental device, compact high-field tokamak codenamed "Morning Light". The startup is pursuing a differentiated technological path centered on a Deuterium-Helium-3 (D-He3) fuel cycle. Its compact D-He3 power plants are designed for flexible deployment near urban centers or data hubs. This strategy would allow them to work in tandem with larger, remote D-T facilities to form an integrated and versatile energy grid.
