A tokamak uses strong toroidal and poloidal magnetic fields to confine a donut-shaped plasma at 100-200 million°C. ITER is the flagship project. CFS's compact tokamak using HTS magnets could accelerate the timeline. The main challenges are plasma disruptions, divertor heat loads, and tritium breeding. - **Stellarator**: Stellarators use complex 3D coil shapes to create inherently stable plasma confinement without requiring a plasma current. This eliminates disruption risk (the biggest tokamak challenge) and enables steady-state operation. Wendelstein 7-X proved that optimized stellarator designs can achieve tokamak-like confinement. The tradeoff: more complex and expensive to build, but potentially more reliable for power plants. - **Inertial Confinement Fusion (ICF)**: ICF uses powerful lasers or projectiles to compress and heat a small fuel capsule to fusion conditions. NIF achieved ignition in 2022, proving the physics works. The challenge is achieving high gain (Q>>10) at high repetition rate (several shots per second) for a power plant. New approaches like Pacific Fusion's pulser-driven ICF aim to make this cheaper and more practical. - **Field-Reversed Configuration (FRC)**: FRC creates a self-contained plasma ring where the plasma generates its own confining magnetic field. This eliminates the need for external magnetic coils, potentially enabling much simpler and cheaper devices. TAE targets aneutronic p-B11 fusion; Helion uses D-He3 with direct energy conversion. Both are backed by major tech investors. - **Z-Pinch / Magneto-Inertial Fusion**: Z-pinch and magneto-inertial approaches aim to simplify fusion by reducing or eliminating external magnetic coils. Zap Energy's sheared-flow Z-pinch stabilizes the plasma using flow shear. General Fusion compresses magnetized plasma with liquid metal pistons. Sandia's MagLIF uses the Z machine to compress magnetized fuel. All aim for simpler, cheaper fusion than tokamaks. - **Aneutronic Fusion (p-B11)**: Aneutronic fusion using hydrogen and boron-11 produces only charged alpha particles, eliminating neutron damage and activation. This enables direct energy conversion (electricity from charged particles, no steam cycle) with potential >80% efficiency. The catch: it requires temperatures of ~1 billion°C, 10x higher than D-T fusion. TAE and HB11 are pursuing different approaches to reach these conditions. - **Magnetized Target Fusion (MTF)**: MTF sits between magnetic and inertial confinement: a magnetized plasma is pre-heated and then compressed to fusion conditions. General Fusion uses liquid metal pistons; Sandia uses electromagnetic compression. MTF aims to achieve fusion at lower cost than tokamaks or laser ICF by using simpler hardware. The key challenge is achieving sufficient compression and confinement simultaneously. - **Direct-Drive ICF**: Direct-drive ICF illuminates the fuel capsule directly with laser beams, avoiding the energy loss of the hohlraum used in NIF's indirect-drive approach. This could achieve higher coupling efficiency (more laser energy reaches the fuel) but requires more uniform laser illumination. The University of Rochester's OMEGA laser and future kJ-class lasers are testing this approach. - **Spherical Tokamak**: Spherical tokamaks have a much smaller hole in the center than conventional tokamaks, making more efficient use of the magnetic field. This enables smaller, potentially cheaper devices. Tokamak Energy's ST40 achieved 100 million°C in 2022 using HTS magnets. They are now building ST80-HTS, a full-scale HTS prototype, targeting commercial deployment by mid-2030s. - **Fusion-Fission Hybrid**: Fusion-fission hybrids use fusion as a neutron source to drive a subcritical fission blanket that generates energy and can burn nuclear waste or breed fuel. The fusion component doesn't need to achieve net energy gain (Q<1 is acceptable) since the fission blanket provides most of the energy. While conceptually interesting, no major program is actively pursuing this approach commercially. - **Pulser-Driven Inertial Fusion (Pacific Fusion)**: Pacific Fusion's approach uses electrical pulsers instead of lasers to drive inertial confinement fusion. In February 2026, they announced a breakthrough finding a cheaper way to make their fusion reactor work. Pulsers are significantly less expensive than the 192-beam laser system used at NIF, potentially offering a more economically viable path to inertial fusion energy. - **Muon-Catalyzed Fusion**: Muon-catalyzed fusion uses muons (heavy electron relatives) to catalyze fusion reactions at room temperature. The muon replaces an electron in a hydrogen molecule, bringing the nuclei 200x closer together and enabling fusion. The problem: producing muons requires enormous energy (particle accelerators), far exceeding the fusion energy released. This remains a laboratory curiosity rather than a practical energy source. - **Dense Plasma Focus (DPF)**: Dense Plasma Focus devices use a high-current electrical discharge between coaxial electrodes to create a dense, hot plasma pinch. LPP Fusion is pursuing p-B11 fusion using this approach, claiming it could reach the required billion-degree temperatures. While the physics is interesting, DPF has not yet demonstrated the confinement times needed for net energy gain. - **Helion's Pulsed FRC with Direct Conversion**: Helion's unique approach combines pulsed FRC technology with direct energy conversion. As the FRC plasma is compressed, the changing magnetic field induces currents that are directly captured as electricity - no steam turbine needed. This could achieve >50% thermal-to-electric efficiency. The D-He3 fuel cycle produces minimal neutrons. Microsoft's PPA for 2028 delivery is the first commercial fusion power agreement. - **Laser-Driven Shock Ignition**: Shock ignition is a variant of ICF that launches a strong shock wave into the fuel at the end of the compression phase. This reduces the laser energy needed for ignition compared to conventional hot-spot ignition. Simulations show it could achieve high gain (Q>50) with significantly less laser energy than NIF, making it a promising path for more economical laser fusion power plants. - **TAE Technologies Norm**: fusion_FRC - **CFS SPARC 75% Complete**: fusion_tokamak - **Helion Polaris D-T Fusion**: fusion_FRC - **IEA State of Energy Innovation 2026 - Fusion Featured**: The IEA's State of Energy Innovation 2026 report formally features fusion energy for the first time, marking a major policy milestone.
