GenF is developing the world’s first commercial inertial confinement fusion (ICF) reactor that produces clean, carbon‑free electricity by using ultra‑high‑energy lasers to compress deuterium‑tritium fuel pellets at high repetition rates. The system captures fusion neutrons to generate thermal energy for a conventional turbine‑generator and includes a self‑sustaining tritium breeding cycle, aiming to deliver gigawatt‑scale baseload power for utilities and large‑scale energy providers.

Problem
Current energy systems rely heavily on fossil fuels, leading to carbon emissions, climate change, and geopolitical supply risks. Existing nuclear power options face challenges related to safety, waste management, and public acceptance, while renewable sources lack the ability to provide continuous, high‑density baseload power.
Solution
GenF is developing the world’s first commercial inertial confinement fusion (ICF) reactor that generates clean, carbon‑free electricity by replicating the processes powering the sun. The reactor uses ultra‑high‑energy lasers to compress cryogenic deuterium‑tritium (DT) fuel pellets at a rate of up to ten shots per second, achieving temperatures above 100 million °C and initiating thermonuclear combustion. Neutrons released from the fusion reaction are captured and converted into thermal energy, which drives a conventional turbine‑generator to produce electricity. The design also incorporates a self‑sustaining tritium breeding cycle, converting neutron‑irradiated lithium into new tritium fuel, ensuring long‑term fuel availability. GenF’s approach leverages deep expertise from Thales, CEA, and CNRS laboratories to integrate advanced laser technology, target manufacturing, and large‑scale project management, aiming to deliver a 1 GW power plant by the 2050s.
