After hitting a pair of important technological milestones, TAE Technologies now believes it will be able to build a commercial-grade fusion reactor by 2030. The company said it can now sustain a plasma for an indefinite amount of time. TAE’s reactor needs to be able to heat plasma to 100 million degrees Celsius, but it recently demonstrated it can get to 50 million degrees C, which gives it confidence it can reach its goal before the end of the decade.

TAE Technologies, a privately-held spinoff of the University of California Irvine founded in 1998, has a proprietary approach to fusion, using a mechanism that produces and confines plasma, and operates at higher temperatures to achieve fusion with better stability and therefore greater safety than other technologies that try to exploit the process that powers the sun.
