Elcogen and Convion have wrapped up 2,000 hours of testing of a solid oxide electrolyzer equipped with Elcogen’s cell technology. The test campaign included steady-state operation and 1,000 rapid power cycles. The companies reported robust system performance, achieving an electrical efficiency exceeding 85%, to produce 39 kWh of electrical energy per kilogram of green hydrogen. In the context of electrolysis, this represents a reduction of 20% to 30% in electricity compared to competing PEM and alkaline technologies. The steam electrolyzer features Elcogen’s Solid Oxide cell and stack technology implemented in Convion’s steam electrolyzer system platform.
