Commercial fusion power plant using scaled planar-coil stellarator technology from Eos to generate grid power.
In concept; construction before 2030, grid power around 2035.
Checked 10 Oct0 updates this week
Helios scales Eos design to higher plasma density and temperature, producing net energy.
Heat from fusion reactions drives steam turbines to generate electricity at grid scale.
