Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [ 1 ]
According to The Financial Times, which first reported the news Sunday, preliminary results show ignition took place, producing 2.5 megajoules of energy, or 120% of the energy that was consumed by ...
Performance was gradually improved until, as of 2024, the fusion energy routinely exceeded 2 MJ. [31] To be useful for energy production, a fusion facility must produce fusion output at least an order of magnitude more than the energy used to power the laser amplifiers – 400 MJ in the case of NIF.

Andrea Lynn "Annie" Kritcher is an American nuclear engineer and physicist who works at the Lawrence Livermore National Laboratory. She was responsible for the development of Hybrid-E, a capsule that enables inertial confinement fusion. She was elected Fellow of the American Physical Society in 2022.
Indeed, the ignition success has spurred public sector investment and excitement in the buzzy world of private fusion, though high interest rates have taken a bite out of new venture capital funding.
That experiment briefly achieved what's known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to the target, the Energy Department said.
