US scientists have achieved net energy gain in a nuclear fusion reaction for the second time since a historic breakthrough in December last year in the quest to find a near-limitless, safe and clean source of energy.

Scientists at the California-based Lawrence Livermore National Laboratory repeated the breakthrough in an experiment in the National Ignition Facility (NIF) on 30 July that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.

Using a 192-beam laser at Lawrence Livermore National Laboratory’s National Ignition Facility, researchers heated and compressed hydrogen atoms, exceeding solar temperatures.

The experiment performed on July 30 had a higher yield than what was obtained in December, a spokesperson said.

Scientists have achieved a net energy gain in nuclear fusion for the second time, marking major progress towards realising the potential of the near-limitless energy source.

A team at the Lawrence Livermore National Laboratory in California, who first achieved the feat last December, claimed to have passed a new milestone with fusion ignition by producing even greater energy output than the original experiment.

The nuclear fusion process has been described as the “holy grail” of clean energy, as it requires no fossil fuels and leaves behind no hazardous waste. Instead it mimics the natural reactions that occur within the Sun, though harnessing its potential has puzzled scientists since the 1950s.

They finally reached ignition again last week, according to a statement Sunday from the lab. The news was first reported by the Financial Times.

“In an experiment conducted on July 30, we repeated ignition,” the statement read. “Analysis of those results is underway. As is our standard practice, we plan on reporting those results at upcoming scientific conferences and in peer-reviewed publications.”

Unlike fission, the process used in current nuclear power plants, fusion involves smashing atoms together instead of splitting them apart. It theoretically can supply carbon-free energy without long-lasting radioactive waste. But generations of scientists have struggled to master it in a controlled reaction, even though it has been the power source of nuclear weapons for decades.

A collaboration of nuclear theorists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Argonne National Laboratory, Temple University, Adam Mickiewicz University of Poland, and the University of Bonn, Germany, has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of “up” and “down” quarks within protons. The results, just published in Physical Review D, revealed key differences in the characteristics of the up and down quarks.

“This work is the first to leverage a new theoretical approach to obtain a high-resolution map of quarks within a proton,” said Swagato Mukherjee of Brookhaven Lab’s nuclear theory group and a co-author on the paper. “Our calculations show that the up quark is more symmetrically distributed and spread over a smaller distance than the down quark. These differences imply that up and down quarks may make different contributions to the fundamental properties and structure of the proton, including its internal energy and spin.”

Co-author Martha Constantinou of Temple University noted, “Our calculations provide input for interpreting data from nuclear physics experiments exploring how quarks and the gluons that hold them together are distributed within the proton, giving rise to the proton’s overall properties.”

With the world looking for cleaner ways to meet its energy demands, nuclear power is gaining favor once again as a low-carbon source of energy. Companies are also focused on harnessing energy from nuclear fusion instead, which does not raise concerns about nuclear waste.

For a moment, imagine a world of limitless energy – one where energy is so abundant that everyone can power their homes and businesses for mere pennies.

These days, it’s tough to imagine a world like that. Last winter, the average U.S. heating bill was $1,000.

ATLANTA (AP) — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.

Georgia Power Co. announced Monday that Unit 3 at Plant Vogtle, southeast of Augusta, has completed testing and is now sending power to the grid reliably.

At its full output of 1,100 megawatts of electricity, Unit 3 can power 500,000 homes and businesses. Utilities in Georgia, Florida and Alabama are receiving the electricity.
