Powdered hydrogen.
Sounds dangerous.
The oil industry uses hydrogen gas at thousands of psi to take the sulfur out of fuels and to hydrocrack long chains into shorter chains if hydrocarbons this is essential to creating the precise C6 to C9 chains, bent chains and ring hydrocarbons we refer to as gasoline. Without massive amounts of hydrogen measured in the millions of lbs per year oil.refineries cease to exist. They are just giant hydrocracking, hydro isomerization, and hydro desulfurization planrs. Oil refineries are the largest user of hydrogen gas in the planet. They need it by the tonne and currently all of that is high pressure gas that leaks through stainless steel and turns it brittle in short order. Refineries have fires and blow up fairly often due to hydrogen leaks. So if they came up with a way to move hydrogen from point A to point B without thousands of psi and release it at will at the point of need it is a substantial breakthrough the oil industry will be all over this like a virgin on prom night.
