Fusion milestone as UK firm builds ‘crucial’ part to harness ‘low cost, limitless’ energy

“The learnings from Demo4 will be a key catalyst for delivering the global deployment of compact, low-cost spherical tokamak power plants. We are proud to be delivering this world-first, complete system of HTS magnetic coils, which will now be assembled into a full tokamak configuration for testing.”

Mr Kelsall previously explained that in order to harness fusion energy, his firm uses magnetic confinement fusion, which involves using what is known as a neutral beam injector to heat two variants of hydrogen, the lightest element of the periodic table.

By heating up deuterium and tritium to around 100 million degrees, these hydrogen isotopes accelerate at higher speeds, collide, and fuse to form helium, with one spare neutron, which he said carries 80 percent of the excess energy that arising from this collision that’s released from this reaction.

He added: “That’s what we harvest ultimately as heat energy to convert into industrial applications in sectors like iron and steel, cement, synthetic fuels, petrochemicals, desalination.
