The Charbone Hydrogen Supply Hub will serve as a dedicated physical storage and local distribution facility, designed to support reliable, on-demand hydrogen supply to industrial, advanced-manufacturing, and mobility customers across Southern Ontario .

Importantly, CHARBONE will use its already existing physical infrastructure for the Hub, including its own hydrogen storage tube assets, and other components, enabling the Company to:

• Secure local inventory and buffer capacity

“ This first Charbone Hydrogen Supply Hub  in Ontario represents a strategic step forward for CHARBONE ,” said Dave Gagnon, CHARBONE’s Chief Executive Officer and Chairman of the Board. “ By investing directly in physical storage assets, we are reinforcing our commitment to local operational control, supply security, and long-term value creation in key industrial markets . ”

The Ontario hub is expected to support multiple type of customers and dedicated customer supply programs, with different delivery formats, including tube trailers and micro-bulk solutions. The Ontario will be designed to accommodate future storage and production capacity expansions as market demand grows.
