Private fusion energy developers have attracted over $6 billion in cumulative private equity by utilizing high-temperature superconducting (HTS) magnets. These advanced magnetics enable smaller tokamak designs capable of confining superheated plasma at commercially viable operational scales.
Grid Interconnection Challenges
While physics milestones advance rapidly, engineering challenges surrounding neutron-resistant structural materials and closed-loop tritium breeding persist. Utility companies estimate first power-purchase agreements (PPAs) will not materialize before the mid-2030s.
