Image caption, The Loop system splits the methane molecules in this metal "balloon" and captures hydrogen for fuel and carbon in the form of graphene Graphene is the thinnest and strongest ...
Red-and-silver water molecules form a cage around two blue-and-silver methane molecules. Two methane molecules are too tight a fit, so a low-energy hydrogen bond -- the red dotted lines -- between ...
However, converting methane to other compounds has proven difficult because getting it to react with other molecules usually requires high temperature and high pressures. To achieve methane ...
