The evolution of traditional Alkaline Water Electrolysis
Water electrolysis has been known for over 200 years, with the first experiment using a voltaic pile to split water dating back to 1800.
By 1902, more than 400 industrial water electrolysis units were in operation. Additionally, different commercial alkaline water electrolyzers were developed in the 20th century to generate the hydrogen needed to produce ammonia using hydroelectricity.
Nowadays, alkaline water electrolysis (AWE) is a mature technology and the most prominent solution for green hydrogen production, as it is a well-established, relatively simple technology, efficient, competitive, and can be coupled with renewable energy sources such as solar or wind power.
