Hydrogen roadmap shows why one little atom holds big peomise

摘要

IT'S the most abundant element in the universe and fuels the powerful fusion reaction that transforms matter into energy in the sun.Yet, hydrogen - the smallest chemical element, with one proton and electron - has, until now, been sidelined in the world's global energy debate. In a sense, hydrogen is hidden from plain sight. It doesn't occur naturally on its own, but is bound to other elements, such as oxygen in water (H20) - the largest pool of hydrogen on Earth - and in carbon-based compounds such as methane (CH.).
