Researchers develop cheaper, more efficient method to extract hydrogen from seawater

Researchers from RMIT University have developed a more cost-effective and energy-efficient way to extract hydrogen from seawater, a development which could advance the establishment of a thriving green hydrogen industry. Splitting seawater directly into hydrogen and oxygen skips the need for desalination and its associated cost, energy consumption and carbon emissions. Green hydrogen made by splitting water is expensive and commercially unviable. The new method takes very little energy to run and could be used at room temperature, making it highly efficient and stable, and therefore promising to significantly bring down the cost of electrolysers. The researchers are now working with industry partners to develop this technology.
