Fusion energy startup Realta Fusion, a University of Wisconsin-Madison partner, announced they are moving into the next phase of their plan to build nuclear fusion devices for real-world deployment.
University of Wisconsin-Madison nuclear fusion startup Realta Fusion raised $36 million dollars with the hope of building the world’s first commercially viable and operating nuclear fusion device prototype by 2028.
The company hopes to advance research into “compact, scalable modular fusion energy” with the venture capital raised, they announced Tuesday.
A fusion device generates electrical power from a nuclear fusion reaction. Currently, no fusion device reliably creates more energy out than energy in, which would be necessary to make fusion energy commercially viable. Realta Fusion aims to change that.
Realta Fusion was the first company to use high-temperature superconducting (HTS) magnets in a magnetic mirror configuration to contain plasma — a step necessary, but not sufficient, for fusion to occur. The HTS magnets are a “game changer” for device compactness and plasma control and confinement, Kieran Furlong, chief executive officer and co-founder of Realta Fusion, told the Cardinal.
