Jack Brouwer, a professor of mechanical and aerospace engineering at UC Irvine and director of the National Fuel Cell Research Center, said hydrogen is more effective for longer storage because it doesn’t lose energy over time and can be stored underground easily and cheaply.

UCI researchers have architecturally designed plate-nanolattices — nanometer-sized carbon structures — that are stronger than diamonds as a ratio of strength to density. The material consists of closely connected, closed-cell plates instead of the cylindrical trusses common in such structures over the past few decades. … The material is fabricated through a 3D laser printing process called two-photon lithography direct laser writing.
