Private fusion energy ventures are shifting focus from physics validation to engineering execution. Recent advances in rare-earth barium copper oxide (REBCO) superconducting tape have allowed developers to construct significantly more compact tokamaks.
Supply Chain Bottlenecks and Regulatory Frameworks
Despite technical breakthroughs, commercial viability depends on resolving material degradation from high-energy neutron flux. Regulators are currently establishing separate safety standards for fusion distinct from conventional fission infrastructure.
