Horne is developing modular fusion systems that combine inertial electrostatic heating, superconducting, magnetically-shielded grid, high-beta capable fusion core, and ion-ion and ion-neutral thermalization mitigation optimization. The result is a non-thermal process that doesn’t require the immense fuel and energy requirements of traditional approaches, without the risk of using radioactive or highly regulated materials. By taking a dual confinement approach, the company says, it's able to conduct faster development cycles with less expensive construction.

Commonwealth Fusion Systems is collaborating with MIT to create SPARC - the world's first fusion device that produces plasma that generates more energy than consumes. This compact, high-field tokamak will be built using high-temperature superconducting (HTS) magnets. CFS technology uses the new superconductor Rare Earth Barium Copper Oxide (REBCO) to produce the most powerful and most compact fusion magnets. Once SPARC is built, the company plans to build the world's first fusion power plant capable of generating hundreds of megawatts of power. CFS research is funded by the U.S. Department of Energy.

Petra Power sells solid oxide fuel cells — ceramic devices that convert fuel, like natural gas, into electric power without burning it. The company markets them as a more efficient and environmentally friendly way to operate data centers and large vehicles. The startup says its fuel cells are super efficient and cut fuel costs during a time when the tech industry can’t get enough electricity.

Type One Energy uses an enhanced version of a 1957 experimental Stellarator invented by US scientist Lyman Spitzer. The co-founders of Type One Energy built the world’s first optimized stellarator at the University of Wisconsin-Madison in the 1990s and conducted foundational stellarator research on it in the early 2000s. Using non-planar, high temperature superconducting magnets to optimize plasma flow, Type One Energy can surpass all fundamental technical barriers to achieving fusion energy at commercial scale. The company is building Infinity One prototype together with the 400 MWe Infinity Two fusion power plant. It plans to buildthe first power plant by 2034
