Since 1920, alkaline electrolysis has been used in applications. This electrolysis technique is the best time-tested technology available today. Alkaline electrolysis technology is very well understood and various aspects of this process have been mastered. It has acquired the reputation of a robust technology during its lengthy commercial service life extending back nearly 100 years. This technology represents the industry standard for commercial-industrial electrolysis systems (large-scale electrolysis), which operates successfully in the megawatt range, and may produce up to 750 Nm3/h of hydrogen in a single installation.
