How does fusion work if it requires antimatter to transform particles into energy?

Answer 1

Nuclear fusion is a nuclear reaction where two or more atomic nuclei crash together at extremely high speed and join to form a new atomic nucleus. For instance, the Sun's intense pressure and temperature cause 620 million metric tonnes (680 imperial tons) to fuse together into helium.

Although antimatter can be used to initialize fusion, it is not a requirement. For instance, acoustic shock waves have been theorized to cause enough temperature and pressure to fuse nuclei together. High temperature is also used in a tabletop fusion device called a Farnsworth-Hirsch fusor.

As well, electrostatic confinement accelerates ions into a space causing them to fuse together in a device called a Polywell.

However, the typical ingredients to cause atomic nuclei to fuse together are temperature and pressure. See the related Wikipedia link below for more information on nuclear fusion.

Answer 2

Fusion does not require antimatter to transform particles into energy. In fusion reactions, atomic nuclei combine to form a heavier nucleus, releasing energy in the process. Antimatter is not typically involved in fusion reactions, as the primary fuel sources are isotopes of hydrogen such as deuterium and tritium.
