Developing safe and clean energy to address climate change and global poverty

Natrium™ Reactor and Integrated Energy Storage

The Natrium™ technology is one of the fastest and lowest-cost paths to advanced clean energy that can change the world. With a sodium fast reactor, integrated energy storage and flexible power production, the Natrium technology offers carbon-free energy at a competitive cost and is ready to integrate seamlessly into electric grids with high levels of renewables. TerraPower and its partners are working to demonstrate this technology at a retiring coal plant in Wyoming.
