Strengthening customer relationships in a strategic market: New York State

Following the announcement on January 14, 2026, regarding an initial order for clean UHP hydrogen from a US customer located in New York State, CHARBONE indicates that this customer is continuing its collaboration with CHARBONE. The new order for CHARBONE’s UHP hydrogen, combined with an initial order for UHP oxygen, represents a further step in CHARBONE's commercial deployment in the United States, a strategic market for future growth.

Diversification of UHP offerings: hydrogen and oxygen

“These new orders, now including distribution and delivery of UHP oxygen, confirm not only that the relationship with our existing customer in New York State is strengthening, but also the relevance of our strategy to diversify into UHP industrial gases,” said Dave Gagnon, CHARBONE’s Chief Executive Officer and Chairman of the Board. “Our objective is clear: to offer reliable supply and first-class purity standards in order to meet the highest demands of the technology and industrial markets in North America.”
