In a set of slides prepared for NIWeek by John Hadjichristos of Defkalion [1], slide 15 talks about the role of hydrogen in LENR. It suggests that hydrogen is excited into a (non-ionized) Rydberg state. In Rydberg hydrogen, the electron is excited above ground, and I believe such states are metastable. Slide 15 explains that Rydberg hydrogen becomes elliptic and hence a dipole, which can then be guided (no doubt by way of an external field of some kind).
I came across an interesting paper that provides visualizations of Rydberg states in hydrogen-like wavefunctions [2]. I think the authors are just using general language, and everything they talk about applies to hydrogen, specifically, in addition to other species. Pages 9, 11, 15, 17 and 20 have some 2-D and 3-D visualizations of the electron orbital at higher energies, deformed under both electrostatic and magnetic fields. Some of the trajectories look a little like trilobites. On page 17, there is what appears to be an unshielded proton surrounded by an elliptic electron orbital.
