Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy. This difference in group arises due to the difference in nuclear binding energy between the atomic nuclei before and after the reaction. Nuclear fusion is the process that powers active or central sequence stars and other high-magnitude stars, where large amounts of energy are released. Nuclear fusion
- The clean energy solution has attracted about $2.8bn (£2.5bn) in global investment over the past year, compared with $1.9bn (£1.6bn) over the past decade.
- There was also a breakthrough in late 2021 when researchers at the Joint European Torus (JET) facility in Oxford released a record-breaking 59 megajoules of fusion - almost tripling the previous 21.7-megajoule record from 1997.
