Bob Cerium is the most common lanthanide and is actually inexpensive in quantity.
The prime application for the so-called "superhydrides" like CeH9+ seems to be superconductivity. However the extremely high "loading" could indicate LENR is facilitated.Pd only goes to 1:1 Here is an article of interest that uses Ce at "only" 9:1 loading.

Nano particles of Ce and H or D may allow fusion to occur or otter t transmutations. The NASNO particle may be an entangled system can under go a phase change with a swap of potential for kenotic energy and conservation of spin and angular momentum.

In this article, by density functional theory studies, we show how a rare earth metal, cerium, binds with hydrogen...Each cerium atom is found to bind eight hydrogen molecules which is a much higher number than has been reported for transition metal atoms.
