Realta Fusion develops fusion energy technology for the production of industrial heat and power. Its magnetic mirror confines a plasma between two high field superconducting magnets. The strong magnetic fields cause charged, energetic particles to bounce back and forth, also known as the mirror effect. The technology uses ion and electron RF heating with high energy neutral particle injection to optimize plasma performance. The startup was the first to successfully power a light bulb using the WHAM demonstration fusion reactor. The power converter is installed at the end of the reactor and generates up to several amperes of electricity at 100 volts.

Xcimer develops laser system Phoenix – the largest privately owned laser system in the world and the company’s prototype for commercializing laser fusion. Housed in Xcimer’s 74,000-square-foot Denver laser facility, Phoenix is a proof of concept for an unconventional fusion architecture: a krypton fluoride (KrF) excimer laser using Stimulated Brillouin Scattering (SBS) to compress a microsecond-long pulse into the nanosecond timescales fusion requires. Phoenix is designed to demonstrate end-to-end integrated operation of excimer amplification and SBS pulse compression.

Kyoto Fusioneering is developing fusion-neutron / breeding-blanket Unity-3 that allows to harvest energy from the reactor while also generating fresh fusion fuel. The breeding blanket design will use liquid lithium, which will absorb both heat and neutrons. As the lithium atoms in the blanket are bombarded with neutrons, they split into helium and tritium, an isotope of hydrogen that’s an important fuel for many reactor designs. The tritium is then separated from the blanket and sent to the reactor, while heat is extracted to generate power. Kyoto Fusioneering is also developing systems to heat fusion fuel into a plasma, recycle unburned fuel from the exhaust, and harvest heat to generate electricity.

Focused Energy is developing fusion reactor that uses lasers to compress fuel (inertial confinement). Lasers strike a fuel target, which is compressed by the laser radiation, creating conditions favorable for fusion. When the atoms within the fuel finally fuse, they release a significant amount of energy. The company bases its design on an experiment conducted at the National Fusion Facility which remains the first and only one to create a controlled nuclear fusion reaction that released more energy than it took to start it. Focused Energy is working on simplifying the fuel target. One simplification involves eliminating the hohlraum - the high-precision gold cylinder that converts laser energy into X-rays.

Inertia is a fusion-energy company that is taking the most direct, scientifically-proven path to commercializing fusion, leveraging the only successful achievement of fusion ignition, using a process that was pioneered at Lawrence Livermore National Laboratory. The startup’s reactor relies on a form of fusion known as inertial confinement. In Inertia’s flavor of inertial confinement, lasers bombard a fuel target, compressing the fuel until atoms inside fuse and release energy. The technique is based on NIF’s designs, in which laser light is converted into X-rays inside the target. The X-rays are what ultimately heat and compress the fuel pellet.
