DOE approves Xcimer’s laser fusion power plant design
The Department of Energy has approved Xcimer Energy's Athena fusion power plant preconceptual technical design. With this milestone achieved, the Denver, Colo.-based company is now moving forward with its plans to develop economical laser inertial confinement fusion using two beamlines, gas laser technology, and a molten salt fusion chamber.
The National Ignition Facility at Lawrence Livermore National Laboratory demonstrated net energy gain from inertial confinement fusion in 2022 using solid-state glass lasers and 192 beamlines.
