Cooper and colleagues demonstrated in previous studies that dry water is also useful for storing methane, a component of natural gas, and may help expand its use as a future energy source. In particular, they hope that engineers can use the powder to collect and transport stranded deposits of natural gas. This also exists on the ocean floor in the form of gas hydrates, a form of frozen methane also known as the “ice that burns.” The powder could also provide a safer, more convenient way to store methane fuel for use in vehicles powered by natural gas “A great deal of work remains to be done before we could reach that stage,” Carter added.
