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.

Fusion and the bounty of electricity

From the time we discovered how the sun produces energy, we have been captivated by the prospect of powering our society using the same principles of nuclear fusion. Fusion energy promises the bounty of electricity we need to live our lives without the pollution inherent in fossil fuels, such as oil, gas, and coal. In addition, fusion energy is free from the stigma that has long plagued nuclear power about the storage and handling of long-lived radioactive waste products, a stigma from which fission power is only just starting to recover in green energy circles.
