Focused Energy pursues commercial fusion power using laser-driven inertial confinement fusion (ICF). Laser pulses compress tiny fuel pellets to the extreme conditions needed for fusion, with the aim of producing carbon-free electricity in a controllable, earthbound setting. The company combines expertise in high-energy lasers, plasma physics, materials science, and power-plant engineering to design lasers, optimize fuel, and build integrated prototypes with scientific and industrial partners to scale toward power generation. Their goal is to achieve commercial readiness in the coming decades and provide safe, abundant carbon-free electricity as part of the global energy mix.

German nuclear plant repurposed for laser fusion electricity production after Focused Energy raises $260M

A German company developing laser fusion technology has secured significant funding and acquired a decommissioned nuclear power plant to advance its work. Focused Energy, which specialises in a variant called inertial confinement fusion, has completed a Series A funding round worth DKK 1.7 billion. The company plans to use the shuttered German nuclear power plant as a facility for producing electricity from laser fusion. Fusion power holds enormous potential as an energy source but remains an unsolved challenge for humanity. Focused Energy is among several companies working to make fusion power commercially viable. The acquisition of the former nuclear facility provides the company with infrastructure to develop and test its fusion technology.
