Why Realta Fusion is building a fusion reactor at an old hot dog factory

Realta Fusion has made a significant decision in its quest to develop cutting-edge fusion technology by choosing the former Oscar Meyer factory in Madison, Wisconsin, as the site for its new research and development center. Kieran Furlong, co-founder and CEO of Realta Fusion, humorously noted the transition from 'sausages to fusion' during a conversation with TechCrunch. The facility, aptly named Forge, is set to produce its first plasma by 2029. Realta Fusion has recently demonstrated its ability to convert energy from fusion reactions directly into electricity, paving the way for future commercial power plants. The location was selected not only for the site’s ample power resources but also due to its proximity to Realta’s headquarters. A key factor in Realta's decision was the bipartisan backing from Wisconsin's state government, including support from both the governor and the legislature. Furlong remarked, "Wisconsin really decided they want to throw their weight behind fusion." This support comes at a time when the demand for electricity is rising sharply, driven by the increasing electrification of the economy and the expansion of AI data centers. This year alone, fusion startups have attracted over $1.5 billion in funding, highlighting the growing interest in this field. Realta Fusion is set to benefit from approximately $55 million in incentives from the state and city, further solidifying its commitment to Wisconsin. The startup has strong connections to the area, having originated from a project at the University of Wisconsin-Madison, which annually produces a talented pool of plasma physicists. In a surprising move, Realta's choice to remain in Wisconsin contrasts with the trend of fusion startups gravitating toward national laboratories or coastal regions. For example, another Wisconsin-based fusion company, Type One Energy, relocated to Tennessee in 2024. Since then, Wisconsin has actively embraced fusion power, with bipartisan legislation providing a sales tax exemption for the fusion industry, which is projected to save Realta around $37.5 million. In addition, Wisconsin is contributing $15 million in enterprise zone tax credits, and Madison has offered $2.8 million in tax increment financing. While other states may have proposed similar financial packages, Furlong emphasized the unique, intangible advantages of being a leader in the state’s fusion initiative. "It’s also advantageous to be the state champion," he stated. "We gain the attention of key stakeholders who can assist us, fostering a path for Realta’s success and positioning Wisconsin as a significant hub for fusion development."
