As a basic chemical industry producing chlorine (Cl2) and caustic soda (NaOH), the value of hydrogen produced as a byproduct of the chlor-alkali industry is increasingly recognized. Compared to dedicated water electrolysis for hydrogen production, chlor-alkali byproduct hydrogen is lower in cost, bu...
Against the backdrop of global energy transition, hydrogen energy is experiencing unprecedented development opportunities. From policy to capital markets, "green hydrogen" has become a frequently used buzzword. In the hydrogen production technology race, besides the well-known alkaline water electro...
I. Overview of Alkaline Water Electrolysis for Hydrogen Production Systems
Alkaline water electrolysis (ALK) refers to the technology of producing hydrogen by electrolyzing water in an alkaline electrolyte environment. The electrolyte is typically a 30% (w/w) potassium hydroxide (KOH) solution. The...
