Company Performance Metrics
- Robert Mumgaard: Chief Executive Officer and Co-Founder
- Martin Greenwald: Co-founderPast Role: Massachusetts Institute of Technology, Former Deputy Director - Plasma Science & Fusion Center
Commonwealth Fusion Systems develops fusion energy systems using high-temperature superconducting (HTS) magnets to create compact tokamak reactors. It is building SPARC, a demonstration device designed to achieve net energy gain from fusion and laying the groundwork for ARC, a grid-connected fusion power plant targeting early 2030s operation. The
company partners with MIT and manufactures its HTS magnets and related components, applying peer-reviewed science in its firewalling of plasma and reactor engineering. It has introduced innovations like the PIT VIPER superconducting cable to support pulsed-power magnet systems and accelerate readiness for commercial fusion.
