Scientists in the US announced that they managed to produce net energy from a nuclear fusion reaction for the second time. The first successful attempt was in December.
According to a statement from the Lawrence Livermore National Laboratory in California, more energy was obtained in the experiment on July 30 than in December.
The lab spokesperson added that the test results are still being reviewed.
In the experiment conducted on December 5, scientists managed to fuse two lighter atoms into a denser atom by aiming a laser on a fuel.
The US Department of Energy said that despite the laser’s consumption of 2.05 megajoules, 3.15 megajoules of energy was obtained as a result of fusion.
The fusion reaction, which is formed by the merging of atoms, is a process that enables the Sun to produce energy as well.
Scientists have been aiming to produce clean nuclear energy by repeating this process on earth for 70 years.
In existing nuclear power plants, it produces energy through the fission reaction of atomic fission, but this leads to nuclear waste that must be stored for millennia.
The energy that can be obtained from 1 kilogram of fusion fuel consisting of heavy forms of hydrogen, deterium and tritium, is equivalent to that obtained from 10 million kilograms of fossil fuels.
Although the fusion experiment was successful, there are still some hurdles to overcome before it can be produced worldwide. Expensive installation costs and the need for power generation on larger scales are two of them.
The spread of this technology in the future may also contribute to the fight against global warming by reducing the need for fossil fuels.
However, scientists emphasize that this will not happen in the near future and state that reducing carbon emissions with current opportunities should not be abandoned.
