An electrolyzer is a device that uses electricity to split water into hydrogen and oxygen through a process called electrolysis. It plays a key role in producing green hydrogen when powered by renewable energy sources like solar or wind. Electrolyzers consist of electrodes and an electrolyte that facilitate the chemical reaction. The hydrogen produced can be stored, transported, or used as a clean fuel for various applications, including industrial processes, power generation, and transportation. There are several types of electrolyzers—such as alkaline, proton exchange membrane (PEM), solid oxide, and anion exchange membrane (AEM)—each with distinct advantages and use cases. 

Governments worldwide are actively driving green hydrogen development through infrastructure investment and supportive policies. These efforts aim to expand market reach, boost electrolyzer production, and lower hydrogen costs. Measures include subsidies, tax incentives, loans, and carbon contracts for difference (CCfDs). In the U.S., the Bipartisan Infrastructure Law allocated USD 750 million in 2024 to fund 52 hydrogen-related projects and an additional USD 8 million for advanced manufacturing of electrolyzer materials. Similarly, the EU’s REPowerEU plan supports renewable hydrogen adoption, while India’s National Green Hydrogen Mission seeks to establish the country as a global leader in green hydrogen production and export. 

A lack of adequate infrastructure poses a significant challenge for the electrolyzer market, particularly in developing robust hydrogen economies. As global demand for green hydrogen increases, gaps in supporting systems hinder the smooth integration of electrolyzer technology into larger energy frameworks. Producing hydrogen through electrolysis requires a comprehensive infrastructure for storage, transport, and distribution to ensure efficient delivery to end users. Without these essential components, the widespread adoption and scalability of green hydrogen remain limited, slowing the growth and impact of electrolyzer technologies across various sectors.
