Technology

Alkaline Water Electrolyzers are reliable and safe, and exhibit lifetimes that can reach up to 15 years; as a result, they constitute the most extended Technology at a commercial level worldwide.

The investment costs have been estimated to be in the range of 1000– 5000 $/kW depending on the Production Capacity. Most of the main manufacturers of Alkaline Water Electrolyzers fabricate Bipolar Modules except for the companies Avalence and Sagim, which use Monopolar Cells. Alkaline Electrolyzers allow significantly efficient Operation with usual values in the range of around 47%–82%.^[1]
