New paint material can harvest hydrogen fuel from the air

Researchers have developed a paint-like product that can turn air into hydrogen fuel. Hydrogen is an extremely clean fuel source, emitting only water when it’s burned. However, the fossil fuels needed to create it negate its environmental benefits, and alternative production methods using liquid water aren’t cost-effective. The newly developed material addresses both problems, drawing water molecules from humid air and using solar energy captured by the paint to split them into their hydrogen and oxygen components....
