Terrestrial Energy Inc. is an advanced nuclear technology company focused on the development and commercialization of its proprietary Integral Molten Salt Reactor (IMSR). As a Generation IV small modular reactor (SMR), the IMSR uses liquid molten salt as both a coolant and a fuel carrier, allowing for high-efficiency, zero-emission power generation. The company's business model centers on selling its reactor technology, engineering services, and intellectual property licensing to electric utilities, heavy industrial operators, and data centers. Rather than operating the plants as an independent power producer, Terrestrial Energy partners with industrial consumers and utilities to deploy its technology. The IMSR is designed to produce both electricity and high-temperature industrial heat, making it suitable for dual-use applications such as chemical synthesis, desalination, and powering hyperscale AI data centers. Headquartered in Charlotte, North Carolina, the company went public in October 2025 via a merger with the special purpose acquisition company HCM II Acquisition Corp. Terrestrial Energy is currently in the pre-commercial phase, actively engaging with regulators like the Canadian Nuclear Safety Commission and the U.S. Department of Energy to license and commission its first commercial plants by the early 2030s.
