Icy hydrogen traps
Hydrogen storage in an environmentally friendly way is still a big issue. This article points to the possibility that hydrogen might exist in icy bodies that we thought were incapable of retaining it.
ScienceDaily Magazine — Scientists Trap Hydrogen Gas In Ice “Cages” — Implications For Fuel Cells And Space Science Until recently, scientists thought that molecular hydrogen (H2) was too small to be contained in clathrate hydrates – crystalline solids where a framework of water molecules enclose molecules of gas. Now, researchers at the Carnegie Institution of Washington’s Geophysical Laboratory, University of Chicago, and Los Alamos National Laboratory, have been able to trap the gas inside water-ice structures forming hydrogen hydrate.
