Electrolyzing Seawater for Hydrogen Generation

Recently, researchers from IIT-Madras have developed critical components for a highly efficient, cost-effective way to electrolyze seawater to generate hydrogen using solar energy.

• Traditional alkaline water electrolysis is energy-intensive, requires expensive materials, and uses fresh water. The researchers have addressed these challenges.

Key Points

• Utilizing Alkaline Seawater: The researchers have designed an electrolyzer that utilizes alkaline seawater instead of pure or fresh water.
• Carbon-Based Electrode Support Material: The team used a carbon-based support material for the electrodes to minimize the possibility of corrosion.
• Transition Metal-Based Catalysts: Transition metal-based catalysts were developed to catalyze both oxygen and hydrogen evolution reactions, enhancing the production of ....
