While increased investment and improved focus of the current research efforts can certainly help to speed up progress, even under optimal conditions the time needed to achieve the first delivery of fusion-produced energy to the electricity grid is considerable, and it is unlikely that fusion can contribute to solving the short-term energy crisis (in the coming decades). Fusion must therefore be considered an energy option for the medium to long term. | While increased investment and improved focus of the current research efforts can certainly help to speed up progress, even under optimal conditions the time needed to achieve the first delivery of fusion-produced energy to the electricity grid is considerable, and it is unlikely that fusion can contribute to solving the short-term energy crisis (in the coming decades).

A [[:Wikipedia:Fusion power|fusion power reactor]] delivering | A [[:Wikipedia:Fusion power|fusion power reactor]] delivering 1 GW of electric power to the network would approximately consume 200 kg of Tritium a year. The current world reserves are about 29 kg of tritium. Thus, a nuclear fusion reactor must provide its own fuel. This is achieved using so-called [[Breeding blanket|breeders]]. Tritium breeders capture the neutrons originating from nuclear fusion reactions, generating tritium that can be used as fuel for the reactor. For more information: [[TECNO_FUS]]. | ||
