China is growing as a hub for active fusion research, as its scientists and entrepreneurs are making significant investments in fusion energy. China has two main fusion enterprises driving scientific advances and investment: the government-funded research based at the Institute of Plasma Physics at the Hefei Institute of Physical Science and the privately-funded fusion research…
The drive to net zero has changed the calculus of the Promethean dream.
Fusion Industry Association CEO Andrew Holland published the opinion piece, “US Must Make an Infrastructure Investment in Fusion Energy” in the Washington Examiner on July 13, 2021, pushing for the American government to increase its funding for fusion energy in order to combat the global climate crisis and assert the United States as a leader…
Magnetic confinement: Plasma is heated to 100 million °C or more, then squeezed and held in place by strong magnetic fields, allowing many fusion reactions to occur. (Example: tokamaks, stellarators)
Inertial confinement: Tiny fuel pellets are struck by powerful lasers. The outer layer explodes outward, compressing the core to fusion conditions for a few nanoseconds, producing a brief but intense pulse of energy from each pellet. (Example: National Ignition Facility)
Hybrid systems: Combine compression (e.g., from lasers, plasma pistons, or mechanical impact) with moderate magnetic fields to reduce energy losses and improve confinement.
Electrostatic fusion: Uses high electric potentials to accelerate ions toward a central reaction zone, causing them to collide at high energies and fuse. The ions are guided and confined by electric fields rather than magnets, creating a compact environment for fusion reactions.
