Unfortunately, one problem _31_: Hydrogen is a gas and cannot easily _32_ pumped into a tank like gasoline. Storage _33_ the form of solid hydrides, chemical compounds of hydrogen and a metal _34_ semimetal, are good storage materials in principle, but have not been well suited _35_ automotive applications. An American research team at the Ford Motor Company in Dearborn and the University of California, Los Angeles, has now _36_ a novel hydride that could be a useful starting point for the development of future _37_ hydrogen-storage materials. As Jun Yang and his team have _38_ an “autocatalytic” reaction mechanism causes the composite made _39_ three different hydrides to rapidly release hydrogen at lower temperatures and _40_ dangerous by-products.
