Researchers at MIT have developed a sustainable method to produce green hydrogen using aluminum extracted from old soda cans and seawater. By treating the aluminum with a rare alloy, they were able to enhance the reaction and recover the metal for reuse. The team discovered that adding coffee grounds to seawater significantly accelerates the hydrogen production process, potentially revolutionizing the industry. This innovation aims to eliminate the need to transport highly volatile green hydrogen, making it safer for use in various modes of transportation. By utilizing this technology, MIT envisions powering marine and underwater vehicles with green hydrogen, with future plans to expand into trucks, trains, and airplanes. The research findings have been published in Cell Reports Physical Science, marking a significant step forward in sustainable energy production.
