Green Hydrogen Production Using Electrolyzers

Green hydrogen production through electrolysis harnesses renewable energy, like solar and wind power, to split water into hydrogen and oxygen. This environmentally friendly method reduces emissions and offers versatile storage options for industrial applications. There are different electrolyzers that can be used.

Proton Exchange Membrane (PEM) Electrolyzers

PEM electrolyzers use a solid polymer electrolyte that only allows hydrogen ions (protons) to pass through to form hydrogen gas on the cathode side.

Alkaline Electrolyzers

Alkaline electrolyzers use an electrolyte solution (usually potassium hydroxide) which allows hydroxide ions through leaving hydrogen gas bubbles.

Solid Oxide Electrolyzers (SOE)

A solid ceramic material is used as the electrolyte at high temperature. Water is used in the form of steam which results in higher energy but produces ultra-pure hydrogen with great efficiency.

Good water quality in hydrogen electrolyzers, ensures optimal performance and longevity in clean energy production. Pristine water quality enhances electrolyser efficiency, safeguarding against mineral deposits and corrosion. Read more from our blog "How to maintain water quality within an electrolyzer".

Achieving optimal hydrogen purity is essential for peak electrolyser performance. High-quality hydrogen not only enhances efficiency but also ensures the reliability of advanced clean energy technologies.

In hydrogen electrolyzers, high-pressure conditions combined with small molecule size increases the risk of leaks. Prioritize robustly designed and tested products, reduce connections, and choose leak-free types. Parker’s precision technology ensures a secure hydrogen environment, preventing leaks and minimizing fugitive emissions.

Hydrogen molecules’ small size can be damaging to metallic materials, affecting their properties and mechanical behavior. Parker's manufacturing processes prioritize quality to minimize operating risks in hydrogen environments.
