What to know about Hydrogen crosses, water stays: Palladium membrane enables ammonia synthesis using water

Researchers at the Korea Institute of Energy Research (KIER) have developed a palladium membrane that selectively transports hydrogen from water for ammonia synthesis. This process aims to reduce carbon emissions by using water and renewable energy instead of fossil fuels and hydrogen gas.
