Aternium Plans Dover, Delaware, Hydrogen Production Operations

08/14/2026
Clean hydrogen company Aternium plans to establish production operations in Dover, Delaware.

The approximately $226 million project will include the purchase of roughly 20 acres at the Garrison Oak Business and Technology Park and the construction of an administration and operations building and two process buildings.

“Dover is the right location to launch Aternium’s vision for rebuilding a critical American supply chain,” said Dr. Andrew Cottone, Founder and CEO of Aternium. “This facility will help secure domestic access to an essential strategic material, create high-quality careers, support advanced manufacturing, and reinforce America’s leadership in energy, technology, and national security.”

Aternium specializes in renewable-powered hydrogen production, deuterium production, chemical manufacturing, process engineering, and development of infrastructure to serve industrial and advanced manufacturing customers.

“This investment puts Delaware at the forefront of the next generation of energy and advanced manufacturing,” noted Governor Matt Meyer. “By producing deuterium, one of the world’s most critical materials for semiconductors, nuclear reactors, fusion energy and pharmaceuticals, Aternium will become one of, if not the only, domestic producer of this essential resource.”

“Aternium's decision to locate its first production facility in Dover is a major win for Central Delaware,” added Kent Economic Partnership Executive Director Linda Parkowski. “This project is a testament to what can be accomplished through strong collaboration between the private sector and our local and state partners. We are proud to have supported Aternium throughout this process and look forward to the creation of high-quality, well-paying jobs and the positive economic impact this investment will bring to our community.”
