Google and Chevron were part of a $250 million funding raise announced Tuesday for TAE Technologies, a nuclear fusion startup with an unconventional strategy that has now raised a total of $1.2 billion. A Japanese investment company, Sumitomo Corporation of Americas, also participated in the round, and will help TAE bring its fusion technology to the Asia-Pacific region. TAE was founded in 1998 and aims to have a commercial scale fusion reactor delivering energy to the grid in the early 2030s.
