Why high pressure alkaline Electrolysis?
Alkaline high-pressure electrolysers split water (H₂O) into hydrogen (H₂) and oxygen (O₂) using an electric current. In alkaline high-pressure electrolysers, this process takes place in an alkaline environment, usually using a potassium hydroxide solution (KOH) as the electrolyte.
The electrolyzers operate at elevated pressure to reduce or eliminate the need for additional mechanical compression. This process increases the efficiency of the hydrogen production.
Alkaline electrolysis is one of the most mature and widely used methods for producing hydrogen. It has several advantages:
Cost-Effectiveness
Alkaline pressurized electrolysis systems tend to have lower capital and operating costs compared to other electrolysis technologies, such as proton exchange membrane (PEM) electrolysis. This makes them economically attractive, especially for large-scale hydrogen production.
No use of rare materials
Proton exchange membrane (PEM) electrolysis cells use iridium, one of the scarcest elements on earth, as catalyst for the oxygen evolution reaction. With our technology there is no need for these metals.
Durability and Longevity
Alkaline pressurized electrolyzers are known for their durability and long operational life. The materials used in these systems are generally robust and withstand the alkaline environment, leading to fewer maintenance requirements high reliability and longer system lifespans.
Scalability
Alkaline pressurized electrolysis systems are well-suited for large-scale hydrogen production. They can be easily scaled up to meet industrial demands, making them a good choice for applications requiring substantial hydrogen volumes.
Efficiency
Alkaline electrolyzers have high efficiency, converting a significant portion of the electrical energy input into chemical energy stored in hydrogen.
Established Technology
The technology behind alkaline pressurized electrolysis is well-established and has been used for decades. This means that there is a wealth of experience and knowledge in the industry, leading to reliable and predictable performance.
Wide Range of Operating Conditions
Alkaline pressurized electrolyzers can operate effectively providing flexibility in various industrial and environmental conditions.
Compatibility with Renewable Energy
Alkaline pressurized electrolysis can be integrated with renewable energy sources, such as fluctuating wind and solar power, to produce green hydrogen. This compatibility enhances the sustainability of hydrogen production processes.
