ARC Clean Energy (also referred to as ARC Clean Technology) is a U.S.–based clean-energy firm with additional offices in Canada that is engineering the ARC-100, an advanced sodium-cooled fast reactor designed to generate 100 MWe of reliable, zero-emission electricity. The modular reactor targets applications ranging from electric grids to heavy industrial facilities and hyperscale AI data centers. ARC participates in the U.S. Department of Energy’s Advanced Reactor Demonstration Program, which aims to accelerate small modular reactor deployment, and it has a global distribution agreement with Korea Hydro & Nuclear Power (KHNP). Strategic engineering partner Hatch has worked with ARC since 2022 to advance Canadian project development. Proceeds from the company’s latest funding will support commercialization of the ARC-100, expansion into international markets, and continued collaboration with the DOE. No revenue or user metrics were disclosed, but the firm positions its technology as a cost-effective, scalable infrastructure solution for growing clean-energy demand.
