The fusion energy landscape is teeming with innovative technologies, each tackling the challenge of harnessing the power of the stars from different angles. These startups are pushing the boundaries of science and engineering, exploring diverse approaches to achieve the holy grail of clean, safe, and abundant energy.

Magnetic Confinement Fusion

Magnetic confinement fusion (MCF) is the most established and widely researched approach to fusion energy. MCF utilizes powerful magnetic fields to confine a hot, ionized gas called plasma, preventing it from touching the reactor walls and allowing it to reach the temperatures and densities necessary for fusion reactions to occur.

• Tokamaks: The most common type of MCF reactor, tokamaks use a combination of toroidal and poloidal magnetic fields to confine the plasma in a doughnut-shaped chamber. They are characterized by their high magnetic field strength and long confinement times. Examples of startups using this technology include Commonwealth Fusion Systems (CFS), a spin-off from MIT, and TAE Technologies, which focuses on advanced tokamak designs.
• Stellarators: Stellarators are a type of MCF reactor that use complex, three-dimensional magnetic fields to confine the plasma. This design offers advantages in terms of plasma stability and potentially higher confinement times, but it is also more complex to build and operate. Examples of startups employing this approach include Helion Energy, which aims to build a compact, high-power stellarator reactor, and General Fusion, which combines stellarator principles with inertial confinement techniques.

Inertial Confinement Fusion

Inertial confinement fusion (ICF) focuses on compressing a small target of fusion fuel to extremely high densities using powerful lasers or particle beams. This rapid compression heats the fuel to fusion temperatures, triggering a burst of energy.

• Laser-driven ICF: This approach utilizes high-energy lasers to rapidly heat and compress the fusion fuel target. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory is a leading example of this technology, although it is a large-scale government project. Startups like Focused Energy are working on developing more compact and efficient laser systems for ICF.
• Magnetized Liner Inertial Fusion (MagLIF): MagLIF combines elements of both MCF and ICF. It uses a magnetic field to pre-compress the fuel target before it is imploded by a high-energy pulse. This approach aims to achieve higher fusion yields and energy gains. General Fusion, mentioned earlier, is also pursuing this approach.

Other Fusion Approaches

• Muon-catalyzed Fusion: This approach uses muons, heavier cousins of electrons, to catalyze fusion reactions. Muons can bind to both protons and deuterons, forming muonic atoms with much smaller radii than their electronic counterparts. This increases the probability of fusion reactions, potentially at lower temperatures. Companies like Tri Alpha Energy are exploring this technology.
• Dense Plasma Focus (DPF): DPF devices create a plasma pinch, focusing a large amount of energy into a small volume, achieving high temperatures and densities. This approach offers a simpler and potentially more cost-effective way to achieve fusion compared to MCF. Startups like Focus Fusion are exploring the potential of DPF technology.
