Fossil fuels likely not going anywhere, despite fusion ‘breakthrough’ touted by Biden officials
Fossil fuels likely not going anywhere, despite fusion 'breakthrough' touted by Biden officials
Fusion technology is promising but years away from usefulness, according to experts, who added that investments in wind, solar, and electric vehicles aren't helping with the climate issue.

A future of nuclear fusion powering the country with limitless, carbon-free energy is promising but remains far out of sight, despite U.S. officials and scientists hailing what they described as a "breakthrough" in fusion technology, according to experts.
"There's a lot of hype and misreporting around this announcement," said Myron Ebell, director of the Center for Energy and Environment at the Competitive Enterprise Institute. "It's more an incremental advance than a breakthrough. Nuclear fusion research is very expensive and requires incredible amounts of energy and technology. This latest technological development is a significant step forward, but we're many decades away from having fusion power for powering our homes."
Federal researchers and Biden administration officials on Tuesday announced they created the first nuclear fusion reaction that generated more energy than was put into it to start the reaction.
"This is one of the most impressive scientific feats in the 21st century," Energy Secretary Jennifer Granholm said at a press conference in Washington. "America has achieved a tremendous scientific breakthrough."
Granholm added that this "landmark achievement" will "go down in the history books."
Scientists from Lawrence Livermore National Laboratory, a federal research facility, used lasers to combine hydrogen atoms into helium, mimicking the fusion reaction that powers the sun and stars. While this process may hold the key to a clean and potentially limitless energy source without the risk of radioactive waste, researchers had been unable to conduct fusion experiments that generated more energy than they consumed — until this month.
Specifically, the latest fusion experiment conducted last week and unveiled on Tuesday put in 2.05 megajoules of energy and resulted in an output of 3.15 megajoules, meaning there was a net gain of energy from the reaction, officials said.
However, this calculation didn't account for the significant amount of energy needed to power the lasers operating the fusion reactor. In this case, 300 megajoules needed to be drawn from the electrical grid to operate the lasers, according to Lawrence Livermore officials who spoke at the press conference.
In other words, even though the fusion reaction itself produced more energy than it consumed, the reaction couldn't have been conducted in the first place without exponentially more power from what could be called the experiment's wall-socket energy.
"So, there are many, many steps that have to be made in order to get to inertial fusion as an energy source," Mark Herrmann, program director for weapon physics and design at Lawrence Livermore, told reporters.
Still, President Biden has a decadal vision, to get to a commercial fusion reactor within 10 years," Granholm said Tuesday. "This shows that it can be done."
Fusion researchers say the earliest viable fusion reactors could come online would be 2040. Other experts argue fusion is unlikely to play a major role in power production before the 2060s or 2070s.
"There are very significant hurdles, not just in the science, but in technology," Kim Budil, director of Lawrence Livermore, said at Tuesday's event. "A few decades of research on the underlying technologies could put us in a position to build a power plant."
Another issue is price, as tritium, one of the key isotopes for fusion reactions, is among the most expensive substances on earth.
