About X Energy

X-energy is delivering the next generation of carbon-free energy by reinventing nuclear power. We believe in leaving a cleaner planet for our children and grandchildren, while continuing to provide sufficient and affordable power to sustain growing populations around the world. That is why we have reinvented nuclear power, with a unique combination of proven technologies and new innovations, to meet our current and future needs. X-energy manufactures fuel that seals uranium particles in a protective coating, which makes meltdown impossible and retains the waste inside forever. We also design plants that unlock the fuel’s potential in a process that’s as clean as wind or solar. When combined, the result is reliable carbon-free baseload power, produced more safely and affordable than ever before and available anywhere, at any time.
