Materials Powering the Future of Energy

The Critical Materials Monitor aims to improve understanding of supply chains essential for the energy transition, the transition to more sustainable energy. It offers insights into the critical minerals required, outlines the components of key technologies, and provides in-depth reserve, production, and trade analysis.

Electrode

Electrode

Electrodes in a hydrogen electrolyzer facilitate the electrolysis process by providing a surface for the electrical reaction that splits water into hydrogen and oxygen. The materials and design of the electrodes are crucial for the efficiency and durability of the electrolyzer. They directly impact hydrogen production rates and energy consumption.

Traded commodities related to Electrode

The United Nations Comtrade database provides detailed trade statistics by product and trading partner. Imported and exported products are classified under the Harmonized Commodity Description and Coding System (HS system), used uniformly by most customs authorities around the world. Based on the latest update of the HS system and data available in UN Comtrade, you can find below the relevant commodities related to this technology, including their HS codes and full descriptions.

We have classified these technology-related commodities into three groups: Midstream (chemical and material inputs of technology components), Downstream (fully assembled components or products), and Waste/Recycling (including recycled or waste products and components). Commodities are further arranged according to the relevant technology components.
