Proton Exchange Membrane (PEM) Electrolysis

Among the leading electrolysis technologies, Proton Exchange Membrane (PEM) systems are expected to dominate the market. In 2023, PEM-based machines account for a substantial market share. These systems are preferred for their ability to produce high-purity hydrogen, their operational flexibility under varying conditions, and their ability to support on-site hydrogen production.

PEM systems are known for their compact design, fast response to dynamic power input (ideal for renewable energy integration), and improved safety due to reduced gas crossover. They are especially suited for high-demand applications such as fuel cell vehicles and grid energy storage. Continuous research is also making PEM systems more durable and cost-efficient, further strengthening their market position.

Alkaline Water Electrolysis

Alkaline Water Electrolysis remains one of the most established and cost-effective hydrogen production methods. These systems have been in use for decades and are known for their low capital cost, robust operation, and long lifespan. Typically operating at moderate temperatures with a liquid electrolyte like potassium hydroxide, alkaline systems are widely used in industrial-scale applications.

Despite their slightly lower efficiency and slower dynamic response compared to PEM systems, advancements in electrode materials and system design are enhancing the performance of alkaline electrolyzers. For large-scale hydrogen generation where cost per kilogram is crucial, alkaline technology remains a competitive and trusted solution.
