Deuterium and tritium are promising fuels for producing energy in future power plants based on fusion energy. Fusion energy powers the Sun and other stars through fusion. These isotopes of hydrogen are the most common in radioisotope thermophotovoltaic (RTPV) systems, which use decay heat from the fuel source to heat the. . Fusion power is a potential method of electric power generation from heat released by nuclear fusion reactions. In fusion, two light atomic nuclei combine to form a heavier nucleus and release energy. Research on fusion reactors began in. . Tritium is claimed to be the most effective component for commercial fusion power generation.
