Fusion will offer clean, abundant and safe electricity for future generations.

Fusion in brief

Bringing the power source of the stars down to Earth could give us low-carbon electricity for millennia to come.
Nuclear fusion is one of the most promising options for generating the cleaner energy the world badly needs. CCFE scientists and engineers are developing the technology to bring fusion electricity to the grid.

Why we need fusion

The race is on to find new, environmentally sustainable forms of electricity to meet the aspirations of a growing world population. 
By 2050, the planet could be using twice as much electricity compared to today. More people and better living standards will lead to a big rise in energy consumption.

How fusion works

In a fusion reaction, energy is released when two light atomic nuclei are fused together to form one heavier atom.
This is the process that powers the Sun and other stars, where hydrogen nuclei are combined to form helium.
