Xcimer Energy

Xcimer Energy is an inertial fusion energy (IFE) company headquartered in Redwood City, California, founded in 2021 by Conner Galloway and Alexander Valys. The company is developing a laser-driven fusion system that integrates low-cost excimer laser technology - the world's highest-energy laser system of its kind - with the HYLIFE reaction chamber concept to achieve controlled nuclear fusion. Unlike other fusion approaches that rely on expensive solid-state lasers, Xcimer's excimer laser architecture is designed to dramatically reduce the cost of the driver system, one of the historically prohibitive barriers to commercially viable inertial confinement fusion (ICF).

Xcimer's approach builds on decades of federally funded fusion research, including breakthroughs at the National Ignition Facility (NIF), which achieved fusion ignition in 2022. By combining that scientific foundation with a more cost-effective laser driver and a proven chamber design, Xcimer aims to overcome the longstanding engineering and economic obstacles that have kept fusion power from reaching the grid. Their system is designed to fire repeatedly - igniting a fusion fuel capsule every few seconds - to generate continuous, carbon-free electricity at scale.

For the US energy supply chain, Xcimer represents a potentially transformative technology: a domestic source of near-limitless, carbon-free baseload power that requires no fossil fuels and produces no long-lived radioactive waste. As a manufacturer of the core laser and chamber equipment needed for fusion power plants, Xcimer sits at a critical equipment manufacturing layer of the future clean energy supply chain. Success could catalyze an entirely new domestic industrial ecosystem around fusion energy components and fuel production.
