Realta Fusion

Realta Fusion develops compact, scalable, modular fusion energy systems designed to decarbonize industrial heat and power through its CoSMo fusion technology. The company applies next-generation technology to the magnetic mirror, a mature fusion concept, to accelerate the adoption of fusion energy faster than conventional approaches. Realta Fusion system designs feature prefabricated modules that can be assembled to meet a wide variety of industrial energy needs, enabling cost-effective energy production competitive with conventional fuels. The company approach offers zero-carbon emissions energy production, addressing the 37 billion metric tons of CO2 released annually from energy combustion and industrial processes. Realta Fusion targets hard-to-decarbonize industrial processes that require high-grade heat, where fusion can provide a clean and sustainable energy source to reduce emissions from sectors that are difficult to electrify. The technology combines breakthrough plasma confinement and heating techniques with compact, scalable, modular system architecture, enabling faster implementation than large-scale fusion reactor projects. By utilizing a modular design approach, Realta Fusion systems can be manufactured, transported, and assembled on-site at industrial facilities, providing localized clean energy generation for industrial applications. Founded in 2021 and headquartered in Madison, Wisconsin, Realta Fusion has raised approximately $45 million in Series A funding from investors including Khosla Ventures, WARF, DOE, TitletownTech, Future Ventures, Avila VC, GSBackers, Mayfield, and SVB. The company employs approximately 61 people and is recognized as a minicorn.
