The article discusses how we can make hydrogen, an important clean energy source, using water splitting and membranes. By combining these technologies, we can create pure hydrogen gas efficiently and sustainably. This approach could help meet a large part of our global energy needs in a way that is good for the environment and affordable. The researchers explore different ways to convert water into hydrogen and then separate the hydrogen using membranes. This study shows that membrane separation techniques can be a valuable tool for producing and recovering hydrogen, making it easier to use this renewable energy source in the future.
