Storing hydrogen fuel in salts — a step toward ‘cleaner’ energy production

Hydrogen gas could someday replace fossil fuels as a ‘clean’ energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers have developed a method to store and release highly pure hydrogen with salts in the presence of amino acids.
