The future Atlantic Hub, which will be managed by its subsidiary CHARBONE Nova Scotia Inc. and operational by June 2026, will serve as a dedicated physical facility for local storage and regional distribution, ensuring a reliable and flexible supply of hydrogen for a variety of demanding industrial users, including the defense, advanced manufacturing, mobility, and energy infrastructure sectors.

• Port infrastructure

• Canadian Navy shipyards and facilities

• Automotive component supply chain

• Advanced zero-emission transportation solutions

This "hub-and-spoke" model is a cornerstone of CHARBONE's strategy to progressively deploy a scalable network of hydrogen and strategic industrial gas supply hubs across Canada and the United States, supporting regional markets through local storage, logistics, and distribution capabilities.

"The Atlantic Canada region represents a strategic market for CHARBONE, particularly due to the presence of high-quality infrastructure, large industrial users, and energy transition initiatives," Dave Gagnon, CHARBONE's Chief Executive Officer and Chairman of the Board said. "The Company anticipates that this hub will play a structuring role in the development of its future North American hydrogen logistics platform."
