Frequently Asked Questions:

What is a hydrogen electrolyzer?

A hydrogen electrolyzer is a device that uses electricity to split water (H₂O) into hydrogen (H₂) and oxygen (O₂), a process called electrolysis. When powered by renewable energy sources like solar or wind, the hydrogen produced is considered "green hydrogen," a clean energy carrier with zero greenhouse gas emissions at the point of production.

How do hydrogen electrolyzers work?

Hydrogen electrolyzers operate by passing an electric current through water, which contains an electrolyte to improve conductivity. Inside the electrolyzer, water molecules are broken down at two electrodes: the anode and the cathode. At the anode, oxygen gas is produced along with protons (in PEM) or hydroxide ions (in alkaline), while at the cathode, these ions combine to form hydrogen gas. The process is clean and produces hydrogen suitable for various industrial and energy applications.

What are the main types of hydrogen electrolyzers?

The primary types of hydrogen electrolyzers include Alkaline Electrolyzers, Proton Exchange Membrane (PEM) Electrolyzers, Solid Oxide Electrolyzer Cells (SOEC), and Anion Exchange Membrane (AEM) Electrolyzers. Alkaline electrolyzers are mature and cost-effective for large-scale production. PEM electrolyzers offer high efficiency and rapid response, suitable for intermittent renewable energy. SOEC technology operates at high temperatures, offering higher electrical efficiency and synergy with industrial waste heat. AEM electrolyzers are emerging, aiming to combine the benefits of alkaline and PEM systems.

What are the key applications of hydrogen electrolyzers?

Hydrogen electrolyzers are crucial for producing green hydrogen, which has diverse applications. Key uses include industrial feedstock (e.g., for ammonia, methanol, and steel production), fuel for transportation (fuel cell electric vehicles, heavy-duty transport, aviation, and marine shipping), energy storage and grid balancing, and direct heating or power generation. Electrolyzers enable the decarbonization of hard-to-abate sectors and support the transition to a sustainable energy system.
