Electrolyzer Technologies for Green Hydrogen

By Mary Page Bailey |

Hydrogen is poised to be a cornerstone of the global energy transition and its production via electrolysis has ignited demand for high-performance electrolyzer units Technological and economic advances have brought hydrogen to the forefront of sustainability strategies in many industries, with end users hoping to capitalize on the promise of significantly reducing, or altogether eliminating, CO2 emissions. Globally, many organizations are developing sustainability and energy initiatives centered around hydrogen, including projects in the U.S., Canada, Saudi Arabia, Denmark, Austria, New Zealand, Australia, Singapore, Germany, Chile, Spain, China, Portugal and Japan.  Electrolyzer basics Much of the activity surrounding hydrogen today involves electrolyzers, which are modular processing units wherein electrical current is applied to split water molecules into hydrogen and oxygen. When powered by renewable electricity sources, such as wind or solar power, electrolyzers produce emissions-free, or “green” H2. FIGURE 1. Electrolyzer manufacturers are expanding capacity to satisfy growing global demand[/caption] In recent years, production of electrolyzers has ramped up significantly to meet global demand for green H2. In June,…
