“Commonwealth Fusion Systems, a start-up founded by scientists at the Massachusetts Institute of Technology, said on Tuesday that it planned to build its first fusion power plant in Virginia, with the aim of generating zero-emissions electricity there in the early 2030s.

The proposed facility is among the first to be announced that would harness nuclear fusion, the process that powers the sun, to produce power commercially, a long-elusive goal that scientists have pursued for the better part of a century.

In theory, a fusion reactor could generate abundant electricity without releasing planet-warming carbon dioxide, and with no risk of large-scale nuclear accidents. But moving the concept out of the lab and onto the power grid has proved immensely difficult.

Commonwealth is the best funded of a crop of start-ups that are hoping to realize fusion’s potential soon. The company is first building a pilot machine in Massachusetts, one it says will demonstrate the feasibility of its technology in 2027.”
