Culture + Values
50% Growth
Global Energy Growth
Global energy demand is expected to rise by 50% over the next 30 years, driven by population growth and economic development.
We’re empowering Solar, wind and hydro are parts of the solution. Nuclear is the only pure base‑load, load‑following, highly scalable, locatable anywhere, stand‑alone or complementary solution. It's an integral piece of the puzzle.
Zero Emissions: 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.
Clean Water: X‑energy’s core competencies in HTGR design and high‑temperature fuel design/manufacture makes a unique and compelling combination to apply our skills to Nuclear Thermal Propulsion.
Space & Nuclear: The world is facing a pair of challenges … global energy demand is expected to rise by 50 % over the next 30 years. At the same time, we must significantly lower carbon emissions.
Our technology relies on physics, not mechanical systems.
