Researchers from Tokomak Energy in the U.K. are claiming a new milestone in thermonuclear fusion. They were able to achieve plasma temperatures in a fusion reactor, known as the ST40 device, hotter than the sun’s core for the first time — reaching 15 million degrees Celsius (59 million degrees Fahrenheit).

It’s a big achievement and is a key step toward the generation of limitless clean energy

Tokamak Energy researchers at a facility in Oxfordshire are attempting to build an affordable fusion reactor to supply the U.K. grid with fusion power by 2030. Tokamak Energy is a privately funded company.

Nuclear fusion is a process that involves the collision of atomic nuclei, which fuse together to form helium atoms. The whole process results in the release of fantastic amounts of energy. This is the same process that powers stars. If we can recreate this process on Earth, we would be able to generate huge amounts of clean energy with no harmful byproducts, such as carbon dioxide emissions or the radioactive waste generated by nuclear fission reactions.

Just one tablespoon of liquid hydrogen fuel can generate as much energy as 28 tons of coal

Scientists consider this achievement to be a big step. Their ultimate goal, however, is to heat the high-energy gas to 100 million degrees Celsius (212 million degrees Fahrenheit).

“We are taking significant steps towards achieving fusion energy, doing so with the agility of a private venture, driven by the goal of achieving something that will have huge benefits worldwide,” said CEO Jonathan Carling.

“Reaching 15 million degrees is yet another indicator of the progress at Tokamak Energy and a further validation of our approach. Our aim is to make fusion energy a commercial reality by 2030. We view the journey as a series of engineering challenges, raising additional investment on reaching each new milestone.”
