DOE Approves Xcimer's Laser Fusion Power Plant Design

The Department of Energy has approved the preconceptual technical design for Xcimer Energy's Athena fusion power plant. This marks a significant step for the Denver-based company in developing economical laser inertial confinement fusion technology. Xcimer aims to simplify and reduce costs associated with laser systems, targeting costs under $100 per joule. The company has completed earlier program milestones under the DOE's Milestone-Based Fusion Development Program. Xcimer's prototype, Phoenix, is the largest privately owned laser system globally and serves as a proof of concept for their fusion architecture. The project is backed by venture capital and technical expertise from the U.S. Naval Research Laboratory. The Athena design includes a molten salt fusion chamber and two beamlines, enhancing scalability and efficiency. The approval allows Xcimer to proceed with subsystem testing and engineering validation for an integrated plant demonstration.

Key Points: • The DOE approved Xcimer Energy's Athena fusion power plant design. • Xcimer aims for laser costs under $100 per joule with simplified technology. • Phoenix, Xcimer's prototype, is the largest privately owned laser system worldwide.
