Fusion is the process that powers our sun and stars.
At UKAEA, we’re recreating this process inside a machine called a tokamak, by heating hydrogen gases up to 150 million degrees centigrade. At temperatures like these the gases form a plasma, releasing helium, a neutron and a huge amount of energy, which can be used to make low-carbon electricity.
Fusion power has the potential to play a crucial role in global energy supplies in the second half of this century, sustaining net zero as the demand for energy continues to grow around the world.
