Fusion energy developer Helion Energy has broken ground on a new facility in Everett, Washington, which will house its seventh generation fusion prototype, known as Polaris. Construction of the facility, which will also produce helium-3 fuel, is expected to be completed in early-2022. Meanwhile, General Fusion and Canadian Nuclear Laboratories are to collaborate on the development of tritium extraction techniques for use in commercial fusion power plants.

The €20bn Iter (International Thermonuclear Experimental Reactor) project will replicate the reactions that power the sun and is intended to demonstrate fusion power can be generated on a commercial scale.
The steel and concrete superstructures nestled in the hills of southern France will house a 23,000-tonne machine, known as a tokamak, capable of creating what is essentially an earthbound star.
Millions of components will be used to assemble the giant reactor, which will weigh 23,000 tonnes and the project is the most complex engineering endeavour in history. Almost 3,000 tonnes of superconducting magnets, some heavier than a jumbo jet, will be connected by 200km of superconducting cables, all kept at -269C by the world’s largest cryogenic plant.

Experimental and theoretical research has shown 'spherical' tokamaks to be a "fast route to fusion" compared with more "conventional" tokamak devices such as Joint European Torus (JET), according to David Kingham, chief executive of Tokamak Energy.
