CX-033530: Project Horizon: Green Aluminum Smelter Project – Phase 1

DOE's Office of Clean Energy Demonstrations (OCED) is proposing to provide funding to Century Aluminum Company (Century) in support of their project to construct a modern, low-emission, U.S. aluminum smelter that would reduce carbon intensity by 75 percent compared to the global average for aluminum smelters of 13.1MT CO2e per ton of aluminum. Century's investment would deploy a high voltage substation and rectifier transformers, allowing smelter to provide flexibility to the grid and to be powered 100 percent renewable or nuclear energy.
