A nominal five (5) kilowatt high temperature solid oxide electrolysis stack that was designed and fabricated by OxEon was successfully started at a customer location in Idaho. The stack performance exceeded the expected performance by >10%. Assuming the continued success of this stack, the customer has expressed interest in purchase of an additional twenty (20) kW of high temperature electrolysis stacks from OxEon. This testing will provide an important third party validation of OxEon high temperature electrolysis technology.
