The US is poised to announce a breakthrough in fusion energy

The US department of energy will announce on Tuesday that scientists at a national lab have made a breakthrough on fusion energy, the process that powers the sun and stars that one day could provide a cheap source of electricity, two sources with knowledge of the matter said.
The scientists at Lawrence Livermore National Laboratory in California have achieved a net energy gain for the first time, in a fusion experiment using lasers, one of the people said. The FT first reported the experiment.
Fusion works when nuclei of two atoms are subjected to extreme heat of 100 million degrees celsius or higher leading them to fuse into a new larger atom, giving off enormous amounts of energy. But the process consumes vast amounts of energy, and the trick has been to get more energy out than goes in and to do so continuously instead of brief moments.
US energy secretary Jennifer Granholm is slated to hold a media briefing on Tuesday
If fusion is commercialised, which backers say could happen in a decade or more, it would have additional benefits including producing energy without radioactive nuclear waste that today’s fission reactors produce.
Running an electric power plant off fusion presents tough hurdles, however, such as how to contain that heat economically and to keep lasers firing consistently. Other methods of fusion use magnets instead of lasers.
US energy secretary Jennifer Granholm is slated to hold a media briefing on Tuesday at 10am EST (5pm SAST) on a “major scientific breakthrough”. The department has no information ahead of the briefing, a spokesman said.
Private industry secured more than US$2.8-billion last year for fusion, according to the Fusion Industry Association for a total of about $5-billion in recent years. — Timothy Gardner, (c) 2022 Reuters
