The US will announce “a major scientific advance” in nuclear fusion

“If this breakthrough (…) is real, it could be a game-changer for the planet,” California Congressman Ted Lieu said after the publication of the Financial Times report.

The US Energy Department said Sunday it is preparing to announce a “major scientific breakthrough this week” in nuclear fusion. The British daily newspaper Financial Times reported hours earlier that researchers at Lawrence Livermore National Laboratory (LLNL), located in California, recently achieved a “net energy gain” from an experimental fusion reactor.

It would be the first time scientists have succeeded in producing more energy in a fusion reaction (like the one that powers the Sun) than they have consumed in the process, which would be a significant breakthrough in the search for carbon-free energy.

“We are excited”

Asked to comment on the FT article, spokespeople for the Department of Energy and LLNL said US Energy Secretary Jennifer Granholm will host an event on Tuesday where she will “announce a groundbreaking major scientist.

The LLNL spokesman added that “the analysis (was) still ongoing”. “We look forward to sharing more information on Tuesday once this process is complete,” she added.

The fusion reaction, which produced a net energy gain of 120%, took place within the last two weeks, the FT reported, citing three people with knowledge of the preliminary results.

Nuclear fusion is considered by its defenders as the energy of tomorrow, especially because it produces little waste and no greenhouse gases.
