The world's largest nuclear fusion project that will replicate reactions in the sun to create the ultimate clean energy source has begun assembly in France.
Located in Provence, the International Thermonuclear Experimental Reactor — or ITER, for short — is expected to start delivering energy in the year 2035.
Fusion power works by colliding heavy hydrogen atoms to form helium — releasing vast amounts of energy in the process, as occurs naturally in the centre of stars.
Seven main international partners are collaborating to bring ITER's practical fusion power to reality — including China, Europe, India, Japan, Russia, South Korea and the US.
The ITER project was launched in 2006 and had originally planned to conduct its first test run this year, to reach full fusion by 2023.
However, the project has faced assorted delays as a result of financing issues, budgetary overrun and, most recently, set-backs due to COVID-19.
